+A calendar module for Roundcube
+-------------------------------
+
+This plugin currently supports a local database as well as a Kolab groupware
+server as backends for calendar and event storage. For both drivers, some
+initialization of the local database is necessary. To do so, execute the
+SQL commands in drivers/<yourchoice>/SQL/<yourdatabase>.initial.sql
+
+The client-side calendar UI relies on the "fullcalendar" project by Adam Arshaw
+with extensions made for the use in Roundcube. All changes are published in
+an official fork at https://github.com/roundcube/fullcalendar
+
+For some general calendar-based operations such as alarms handling or iCal
+parsing/exporting this plugins requires the `libcalendaring` plugin which
+is also part of the Kolab Roundcube Plugins repository. Make sure that plugin
+is installed and configured correctly.
+
+For recurring event computation, some utility classes from the Horde project
+are used. They are packaged in a slightly modified version with this plugin.
+
+IMPORTANT
+---------
+
+The calendar module makes heavy use of PHP's DateTime as well as DateInterval
+classes. The latter one requires at least PHP 5.3.0 to run.
+
+
+REQUIREMENTS
+------------
+
+Some functions are shared with other plugins and therefore being moved to
+library plugins. Thus in order to run the calendar plugin, you also need the
+following plugins installed:
+
+* libcalendaring [1]
+* libkolab [1] (when using the 'kolab' driver)
+
+
+INSTALLATION
+------------
+
+For a manual installation of the calendar plugin (and its dependencies),
+execute the following steps. This will set it up with the database backend
+driver.
+
+1. Get the source from git
+
+  $ cd /tmp
+  $ git clone git://git.kolab.org/git/roundcubemail-plugins-kolab
+  $ cd /<path-to-roundcube>/plugins
+  $ cp -r /tmp/roundcubemail-plugins-kolab/plugins/calendar .
+  $ cp -r /tmp/roundcubemail-plugins-kolab/plugins/libcalendaring .
+
+2. Create calendar plugin configuration
+
+  $ cd calendar/
+  $ cp config.inc.php.dist config.inc.php
+  $ edit config.inc.php
+
+3. Initialize the calendar database tables
+
+  $ mysql roundcubemail < drivers/database/SQL/mysql.initial.sql
+
+4. Enable the calendar plugin
+
+  $ cd ../../
+  $ edit config/config.inc.php
+
+Add 'calendar' to the list of active plugins:
+
+  $config['plugins'] = array(
+    (...)
+    'calendar',
+  );

+UPGRADING instructions
+======================
+
+To update database schema, depending on the driver you're using,
+please run in Roundcube bin/ directory:
+
+updatedb.sh --package=calendar-<driver> --version=<version> \
+  --dir=../plugins/calendar/drivers/<driver>/SQL
+
+[*] Replace <driver> with "database" or "kolab" (without quotes)
+[*] Replace <version> with Roundcube version e.g. 0.9.0
+[*] Roundcube should be upgraded before plugin upgrades
+
+Example:
+
+updatedb.sh --package=calendar-kolab --version=0.9.0 \
+  --dir=../plugins/calendar/drivers/kolab/SQL

It is a technique which can be used to isolate features of a particular shape within an image. Because it requires that the desired features be specified in some parametric form, the classical Hough transform is most commonly used for the de- tection of regular curves such as lines, circles, ellipses, etc. A generalized Hough transform can be employed in applications where a simple analytic description of a feature(s) is not possible. Due to the computational complexity of the generalized Hough algorithm, we restrict the main focus of this discussion to the classical Hough transform. Despite its domain restrictions, the classical Hough transform (hereafter referred to without the classical prefix ) retains many applications, as most manufac- tured parts (and many anatomical parts investigated in medical imagery) contain feature boundaries which can be described by regular curves. The main advantage of the Hough transform technique is that it is tolerant of gaps in feature boundary descriptions and is relatively unaffected by image noise.");

+
+Handle Event Invitations
+========================
+
+In chapter :ref:`calendar-event-participants` we have learned how to invite
+other people to an event. This will send out invitation emails to all the 
+participants with the event data attached. That allows one to directly accept
+or decline an event invitation.
+
+
+Receive Event Invitations
+-------------------------
+
+When the webmail system opens an invitation email with event data attached, it'll 
+display a yellow box in the preview pane or the email view:
+
+.. image:: _static/_skin/itip-invitation.png
+
+Accept/Decline Invitations
+--------------------------
+
+Right in the box shown above, you can accept or decline the invitation by clicking the according
+button. This will send an automated response to the event organizer informing her about your
+decision and letting her update your participant status in her calendar.
+
+In case you accept, by either clicking *Accept* or *Maybe*, this will also copy
+the event into your personal calendar. The selector right next to the buttons lets you
+choose the right one.
+
+The copy in your calendar now knows about the invitation and its original sender. If you now
+delete it from your calendar, you'll be asked whether this should send a declination
+message to the person who organizes the event.
+
+After acceping or declining, the email message containing the invitation can be deleted.
+
+
+Process Invitation Replies
+--------------------------
+
+As an organizer who has invited others to an event, you'll receive responses to the
+automatically sent invitations when the attendees either accept or decline them.
+
+Such messages are also identified by the webmail system and again a yellow box appears
+in the message view:
+
+.. image:: _static/_skin/itip-reply.png
+
+By clicking the *Update the participant's status* button, the original event in
+your calendar will be updated with the RSVP status from the person who responded here.
+
+When you now look at the event details in the calendar view, the status icons next
+to each participant now displays the new status.

+Manage Your Schedule
+====================
+
+All functions to maintain your events are accessible from the main calendar view.
+
+
+Add Events to a Calendar
+------------------------
+
+**Via toolbar** 
+    Click the *New event* button in the toolbar to get an empty dialog where you enter
+    the :ref:`event properties <calendar-edit-event>` such as summary, date/time, reminders, etc.
+    Click *Save* to finally add it to the selected calendar.
+
+**At a specific date/time**
+    Navigate the calendar view to the date you want to add an event for. Then mark the range
+    of time (or dates in month view) with the mouse by pressing the button at the time the event
+    should start and releasing it again at time it finishes. This will open the :ref:`event dialog <calendar-edit-event>`
+    with the selected date/time range already filled in.
+
+    In order to create new all-day events, double-click the desired day in the calendar view.
+
+
+.. index:: Recurring events, Participants, Participants
+.. _calendar-edit-event:
+
+Edit and Reschedule Events
+--------------------------
+
+The Event Dialog
+^^^^^^^^^^^^^^^^
+
+When clicking an event in the calendar view, a dialog showing its details is displayed.
+Clicking the *Edit* button in that dialog opens the form to edit all properties of the selected event.
+
+The edit form is divided into different section which can be switched using the tabs on top
+of the dialog:
+
+**Summary**
+
+This general section has text fields and selectors for various properties of an event.
+Here's a description of all the possible values:
+
+* ``Summary``: The title of the event. This is what you will see in the calendar view.
+* ``Location``: Where the event will be taking place.
+* ``Description``: Any text that describes the event.
+* ``URL``: A link to more information about this event.
+* ``Start``: Date and time when the event starts.
+* ``End``: Date and time when the event starts.
+* ``all-day``: Check this if the event has no start/end time.
+* ``Reminder``: Will pop up with an notification at a the specified time before the event.
+* ``Calendar``: The calendar the event is saved in. Change it to move an event from one calendar to another.
+* ``Category``: The type of event. Categories can also be used for :ref:`coloring <settings-calendar>`.
+* ``Show me as``: The representation in your free/busy scheduling calendar visible to others.
+* ``Priority``: The priority value of the event.
+* ``Privacy``: Flag an event as "private" or "confidential" when sharing your calendar with others.
+
+**Recurrence**
+
+For periodically recurring event series, this tabs has the settings how an event is repeated
+over time.
+
+* ``Repeat``: Start with selecting a repetition interval (e.g. monthly)
+* ``Every``: How often the frequency will be relevant. For example, for an event that takes place every other week choose Weekly and then 2.
+  If you choose a frequency of weekly or monthly you can select which days of the week or month the event will occur.
+* ``Until``: Determines the duration of the repetition. The recurrence can either run forever, for a number it times or until a specific date.
+
+**Participants**
+
+An important part of managing your schedule is to invite others to events and track their RSVP.
+In this part of the edit dialog you can manage the participants of an event. Read more about this
+further down in the :ref:`calendar-event-participants` section.
+
+**Attachments**
+
+Sometimes a description text isn't enough to collect information for a specific event.
+Switch to this tab to attach files to the current event or to remove them again. Adding
+files works pretty much the same as :ref:`attaching them to email messages <mail-compose-attachments>`:
+first select a file from your local disk and click *Upload* in order to attach it.
+
+.. note:: Don't forget to finally save the changes by clicking *Save* in the event edit dialog.
+    Even switching back and forth the tabs will not yet save the data.

+
+Moving and Resizing with the Mouse
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. container:: image-right
+
+    .. image:: _static/_skin/event-resize.png
+
+    If an existing event shall be rescheduled to another time or date, you'll find it handy
+    to do that directly in the calendar view without opening the edit form. Simply grab the event
+    block with the mouse and move it to the new date or time. Release the mouse button to complete.
+
+    In *Month* and *Day* view, the event blocks have a small handle at the bottom. Drag this with the
+    mouse in order to resize the event meaning to adjust its duration.

+    before the event starts. You can specify if you want to see alarms for every calendar individually.
+    Enable or disable reminders in :ref:`Calendar Settings <calendar-edit-properties>` from the :ref:`calendar-lists`.
+
+Dismiss or Snooze Reminders
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When a reminder box pops up, you can either dismiss the notification for all events or each one individually.
+When dismissed, no further reminders will be displayed. Choose a time from the *Snooze* menu to get another
+reminder after the selected time.

+Inviting Other People
+---------------------
+
+If you need to set up a meeting, and keep track of who's attending and who is not, the calendar can do this
+as well as you to automatically send invitations and read their responses.
+
+When creating a new event, switch to the *Participants* tab. You're already listed as the organizer of the event.
+
+.. image:: _static/_skin/event-participants.png
+
+1. Enter the name or email address of the person to invite. Contacts from the address book are suggested as you type.
+   In order to send invitations, make sure the entered contact has an email address. Type it in the form
+   ``Person Name <email@address.com>``.
+2. Click *Add participant* to add the person to the list.
+3. Select a *Role* (e.g. required or optional) for this person.
+4. Repeat 1-3 for further participants.
+5. Check the *Send invitations* box if the application should send out invitation emails.
+
+Invitations will be sent out when you click *Save* and the event is created.

+
+    .. index:: Availability
+    .. _calendar-availability-finder:

+    Find Availability
+    ^^^^^^^^^^^^^^^^^
+
+    Once all the participants are added to the list, you see the individual availability status for each one
+    of them, given that this information is available. In case not everybody is free, click the *Find availability...*
+    button to open the scheduling dialog. In that dialog, detailed availability information for all participants is
+    displayed. Use the *Previous/Next Slot* buttons to find the next time slot where all required participants are
+    available. Or drag the gray area representing the event duration with the mouse to manually select a free slot.
+
+    Click *Select* to copy the rescheduled date/time back into the event form and to close this dialog.

+Overview
+*************
+
+The screen of the calendar module presents the following parts: the :ref:`Calendar View <calendar-view>`
+itself, a small :ref:`Calendar Widget <calendar-minicalendar>` the :ref:`calendar-lists` as well as the usual
+toolbar and search box.
+
+
+.. index:: Month View, Week View, Day View, Agenda
+.. _calendar-view:
+
+Calendar View
+=============
+
+The central part of the screen displays the schedule with events from the active calendars matching the current
+date range. The active date range is displayed above the calendar in the toolbar area and can be moved forward or
+backward in time using the arrow buttons right next to the title.
+
+.. image:: _static/_skin/calendar-header.png
+
+
+Change Views
+------------
+
+You can view your calendar events in Day, Week, Month or Agenda view. Toggle the view mode using the toolbar buttons
+above the calendar view.
+
+**Day**
+    All events of a single day appear at the time the begin and spawn a box until their end time. The time
+    scale is displayed in the left side of the view. All-day events appear at the top.
+
+**Week**
+    Similar to the day view but lists all days of the week horizontally. All-day events again appear at the top.

+    Sharing Calendars
+    =================
+
+    For collaboration, sharing calendars is an important feature. In the :ref:`overview <calendar-lists>`,
+    we have already learned how calendars others share with you appear in the calendars list. The following
+    now explains how to make personal calendars accessible to fellow users.
+
+
+    Share a Calendar with others
+    ----------------------------
+
+    Sharing is controlled through the :ref:`Calendar Settings Dialog <calendar-edit-properties>`.
+    Double-click a calendar in the list on the left and then select the *Sharing* tab at the top of
+    the dialog box:
+
+    .. image:: _static/_skin/calendar-acl.png
+
+    The table displays who already has permission to see and modify the selected calendar.
+    In order to share the calendar with a new user do
+
+    1. Click the *Add entry* button (+) in the table footer
+    2. Enter the username or choose one from the autocompletion menu that appears when you start typing.
+       Instead of a specific user, permissons can be granted for all users or guests.
+    3. Select the access rights you want to grant for the user
+    4. Click *Save* to add the permission
+
+    Double-click an entry to edit the permissions for a particular user or group.
+
+    For removing existing permissions, select the according entry in the list and then choose
+    *Delete* from the menu behind the gear icon in the footer of the list.
+
+
+    Subscribe to Shared Calendars
+    -----------------------------
+
+    Calendars shared by others are not showing up right away in the list within the calendar view.
+    Switch to :ref:`Settings > Folders <settings-folders>` to see all resources you can access.
+    There's a shortcut to this: click *Manage folders* in the options menu behind the gear icon
+    located the footer of the calendars list.
+
+    In order to make a shared calendar appear in the calendars list, locate it in the folder manager
+    and check the *Subscribed* mark in the list. Only subscribed calendars are visible in the calendar view.

+	* Includes changes from version 1.7.3.
+	* Fixed: Typo in 1.7 migration script caused it to fail.
+
+1.8.0-stable (2012-11-08)
+	* The zip release ships with sabre/vobject 2.0.5.
+	* BC Break: Moved the entire codebase to PHP namespaces.
+	* BC Break: Every backend package (CalDAV, CardDAV, Auth, Locks,
+	  Principals) now has consistent naming conventions. There's a
+	  BackendInterface, and an AbstractBackend class.
+	* BC Break: Changed a bunch of constructor signatures in the CalDAV
+	  package, to reduce dependencies on the ACL package.
+	* BC Break: Sabre_CalDAV_ISharedCalendar now also has a getShares method,
+	  so sharees can figure out who is also on a shared calendar.
+
+	* Added: Sabre_DAVACL_IPrincipalCollection interface, to advertise support
+	  for principal-property-search on any node.
+	* Added: Simple console script to fire up a fileserver in the current
+	  directory using PHP 5.4's built-in webserver.
+	* Added: Sharee's can now also read out the list of invites for a shared
+	  calendar.
+	* Added: The Proxy principal classes now both implement an interface, for
+	  greater flexiblity.
+
+1.7.8-stable (2013-06-17)
+	* The zip release ships with sabre/vobject 2.1.0.
+	* Changed: OldSabre\DAV\Client::verifyPeer is now a protected property
+	 (instead of private).
+	* Fixed: Text was incorrectly escaped in the Href and HrefList properties,
+	  disallowing urls with ampersands (&) in them.
+	* Added: deserializer for OldSabre\DAVACL\Property\CurrentUserPrivilegeSet.
+	* Fixed: Issue 335: Client only deserializes properties with status 200.
+	* Fixed: Issue 341: Escaping xml in 423 Locked error responses.
+	* Added: Issue 339: beforeGetPropertiesForPath event.
+
+1.7.7-stable (2013-04-11)
+	* The zip release ships with sabre/vobject 2.0.7.
+	* Fixed: Assets in the browser plugins were not being served on windows
+	  machines.
+
+1.7.6-stable (2013-04-08)
+	* The zip release ships with sabre/vobject 2.0.7.
+	* Fixed: vcardurl in database schema can now hold 255 characters instead
+	  of 80 (which is often way to small).
+	* Fixed: The browser plugin potentially allowed people to open any
+	  arbitrary file on windows servers (CVE-2013-1939).
+
+1.7.5-stable (2013-03-01)
+	* The zip release ships with sabre/vobject 2.0.6.
+	* Change: No longer advertising support for 4.0 vcards. iOS and OS X
+	  address book don't handle this well, and just advertising 3.0 support
+	  seems like the most logical course of action.
+	* Added: ->setVerifyPeers to Sabre_DAV_Client (greatly resisting against
+	  it, don't use this..).
+
+1.7.4-stable (2013-01-19)
+	* The zip release ships with sabre/vobject 2.0.5.
+	* Changed: To be compatibile with MS Office 2011 for Mac, a workaround was
+	  removed that was added to support old versions of Windows XP (pre-SP3).
+	  Indeed! We needed a crazy workaround to work with one MS product in the
+	  past, and we can't keep that workaround to be compatible with another MS
+	  product.
+	* Fixed: expand-properties REPORT had incorrect values for the href
+	  element.
+	* Fixed: Range requests now work for non-seekable streams. (Thanks Alfred
+	  Klomp).
+	* Fixed: Changed serialization of {DAV:}getlastmodified and
+	  {DAV:}supportedlock to improve compatiblity with MS Office 2011 for Mac.
+	* Changed: reverted the automatic translation of 'DAV:' xml namespaces to
+	  'urn:DAV' when parsing files. Issues were reported with libxml 2.6.32,
+	  on a relatively recent debian release, so we'll wait till 2015 to take
+	  this one out again.
+	* Added: Sabre_DAV_Exception_ServiceUnavailable, for emitting 503's.
+
+1.7.3-stable (2012-12-01)
+	* The zip release ships with sabre/vobject 2.0.5.
+	* Fixed: Removing double slashes from getPropertiesForPath.
+	* Change: Marked a few more properties in the CardDAV as protected,
+	  instead of private.
+	* Fixed: SharingPlugin now plays nicer with other plugins with similar
+	  functionality.
+	* Fixed: Issue 174. Sending back HTTP/1.0 for requests with this version.
+
+1.7.2-stable (2012-11-08)
+	* The zip release ships with sabre/vobject 2.0.5.
+	* Added: ACL plugin advertises support for 'calendarserver-principal-
+	  property-search'.
+	* Fixed: [#153] Allowing for relative http principals in iMip requests.
+	* Added: Support for cs:first-name and cs:last-name properties in sharing
+	  invites.
+	* Fixed: Made a bunch of properties protected, where they were private
+	  before.
+	* Added: Some non-standard properties for sharing to improve
+	  compatibility.
+	* Fixed: some bugfixes in postgres sql script.
+	* Fixed: When requesting some properties using PROPFIND, they could show
+	  up as both '200 Ok' and '403 Forbidden'.
+	* Fixed: calendar-proxy principals were not checked for deeper principal
+	  membership than 1 level.
+	* Fixed: setGroupMemberSet argument now correctly receives relative
+	  principal urls, instead of the absolute ones.
+	* Fixed: Server class will filter out any bonus properties if any extra
+	  were returned. This means the implementor of the IProperty class can be
+	  a bit lazier when implementing.
+
+Note: bug numbers after this line refer to Google Code tickets. We're using
+github now.
+
+1.7.1-stable (2012-10-07)
+	* Fixed: include path problem in the migration script.
+
+1.7.0-stable (2012-10-06)
+	* BC Break: The calendarobjects database table has a bunch of new
+	  fields, and a migration script is required to ensure everything will
+	  keep working. Read the wiki for more details.
+	* BC Break: The ICalendar interface now has a new method: calendarQuery.
+	* BC Break: In this version a number of classes have been deleted, that
+	  have been previously deprecated. Namely:
+		- Sabre_DAV_Directory (now: Sabre_DAV_Collection)
+		- Sabre_DAV_SimpleDirectory (now: Sabre_DAV_SimpleCollection)
+	* BC Break: Sabre_CalDAV_Schedule_IMip::sendMessage now has an extra
+	  argument. If you extended this class, you should fix this method. It's
+	  only used for informational purposes.
+	* BC Break: The DAV: namespace is no longer converted to urn:DAV. This was
+	  a workaround for a bug in older PHP versions (pre-5.3).
+	* Removed: Sabre.includes.php was deprecated, and is now removed.
+	* Removed: Sabre_CalDAV_Server was deprecated, and is now removed. Please
+	  use Sabre_DAV_Server and check the examples in the examples/ directory.
+	* Changed: The Sabre_VObject library now spawned into it's own project!
+	  The VObject library is still included in the SabreDAV zip package.
+	* Added: Experimental interfaces to allow implementation of caldav-sharing.
+	  Note that no implementation is provided yet, just the api hooks.
+	* Added: Free-busy reporting compliant with the caldav-scheduling
+	  standard. This allows iCal and other clients to fetch other users'
+	  free-busy data.
+	* Added: Experimental NotificationSupport interface to add
+	  caldav notifications.
+	* Added: VCF Export plugin. If enabled, it can generate an export of an
+	  entire addressbook.
+	* Added: Support for PATCH using a SabreDAV format, to live-patch files.
+	* Added: Support for Prefer: return-minimal and Brief: t headers for
+	  PROPFIND and PROPPATCH requests.
+	* Changed: Responsibility for dealing with the calendar-query is now
+	  moved from the CalDAV plugin to the CalDAV backends. This allows for
+	  heavy optimizations.
+	* Changed: The CalDAV PDO backend is now a lot faster for common
+	  calendar queries.
+	* Changed: We are now using the composer autoloader.
+	* Changed: The CalDAV backend now all implement an interface.
+	* Changed: Instead of Sabre_DAV_Property, Sabre_DAV_PropertyInterface is
+	  now the basis of every property class.
+	* Update: Caching results for principal lookups. This should cut down
+	  queries and performance for a number of heavy requests.
+	* Update: ObjectTree caches lookups much more aggresively, which will help
+	  especially speeding up a bunch of REPORT queries.
+	* Added: Support for the schedule-calendar-transp property.
+	* Fixed: Marking both the text/calendar and text/x-vcard as UTF-8
+	  encoded.
+	* Fixed: Workaround for the SOGO connector, as it doesn't understand
+	  receiving "text/x-vcard; charset=utf-8" for a contenttype.
+	* Added: Sabre_DAV_Client now throws more specific exceptions in cases
+	  where we already has an exception class.
+	* Added: Sabre_DAV_PartialUpdate. This plugin allows you to use the
+	  PATCH method to update parts of a file.
+	* Added: Tons of timezone name mappings for Microsoft Exchange.
+	* Added: Support for an 'exception' event in the server class.
+	* Fixed: Uploaded VCards without a UID are now rejected. (thanks Dominik!)
+	* Fixed: Rejecting calendar objects if they are not in the
+	  supported-calendar-component list. (thanks Armin!)
+	* Fixed: Issue 219: serialize() now reorders correctly.
+	* Fixed: Sabre_DAV_XMLUtil no longer returns empty $dom->childNodes
+	  if there is whitespace in $dom.
+	* Fixed: Returning 409 Conflict instead of 500 when an attempt is made to
+	  create a file as a child of something that's not a collection.
+	* Fixed: Issue 237: xml-encoding values in SabreDAV error responses.
+	* Fixed: Returning 403, instead of 501 when an unknown REPORT is
+	  requested.
+	* Fixed: Postfixing slash on {DAV:}owner properties.
+	* Fixed: Several embarrassing spelling mistakes in docblocks.
+
+1.6.10-stable (2013-06-17)
+	* Fixed: Text was incorrectly escaped in the Href and HrefList properties,
+	  disallowing urls with ampersands (&) in them.
+	* Fixed: Issue 341: Escaping xml in 423 Locked error responses.
+
+1.6.9-stable (2013-04-11)
+	* Fixed: Assets in the browser plugins were not being served on windows
+	  machines.
+
+1.6.8-stable (2013-04-08)
+	* Fixed: vcardurl in database schema can now hold 255 characters instead
+	  of 80 (which is often way to small).
+	* Fixed: The browser plugin potentially allowed people to open any
+	  arbitrary file on windows servers. (CVE-2013-1939).
+
+1.6.7-stable (2013-03-01)
+	* Change: No longer advertising support for 4.0 vcards. iOS and OS X
+	  address book don't handle this well, and just advertising 3.0 support
+	  seems like the most logical course of action.
+	* Added: ->setVerifyPeers to Sabre_DAV_Client (greatly resisting against
+	  it, don't use this..).
+
+1.6.6-stable (2013-01-19)
+	* Fixed: Backported a fix for broken XML serialization in error responses.
+	 (Thanks @DeepDiver1975!)
+
+1.6.5-stable (2012-10-04)
+	* Fixed: Workaround for line-ending bug OS X 10.8 addressbook has.
+	* Added: Ability to allow users to set SSL certificates for the Client
+	  class. (Thanks schiesbn!).
+	* Fixed: Directory indexes with lots of nodes should be a lot faster.
+	* Fixed: Issue 235: E_NOTICE thrown when doing a propfind request with
+	  Sabre_DAV_Client, and no valid properties are returned.
+	* Fixed: Issue with filtering on alarms in tasks.
+
+1.6.4-stable (2012-08-02)
+	* Fixed: Issue 220: Calendar-query filters may fail when filtering on
+	  alarms, if an overridden event has it's alarm removed.
+	* Fixed: Compatibility for OS/X 10.8 iCal in the IMipHandler.
+	* Fixed: Issue 222: beforeWriteContent shouldn't be called for lock
+	  requests.
+	* Fixed: Problem with POST requests to the outbox if mailto: was not lower
+	  cased.
+	* Fixed: Yearly recurrence rule expansion on leap-days no behaves
+	  correctly.
+	* Fixed: Correctly checking if recurring, all-day events with no dtstart
+	  fall in a timerange if the start of the time-range exceeds the start of
+	  the instance of an event, but not the end.
+	* Fixed: All-day recurring events wouldn't match if an occurence ended
+	  exactly on the start of a time-range.
+	* Fixed: HTTP basic auth did not correctly deal with passwords containing
+	  colons on some servers.
+	* Fixed: Issue 228: DTEND is now non-inclusive for all-day events in the
+	  calendar-query REPORT and free-busy calculations.
+
+1.6.3-stable (2012-06-12)
+	* Added: It's now possible to specify in Sabre_DAV_Client which type of
+	  authentication is to be used.
+	* Fixed: Issue 206: Sabre_DAV_Client PUT requests are fixed.
+	* Fixed: Issue 205: Parsing an iCalendar 0-second date interval.
+	* Fixed: Issue 112: Stronger validation of iCalendar objects. Now making
+	  sure every iCalendar object only contains 1 component, and disallowing
+	  vcards, forcing every component to have a UID.
+	* Fixed: Basic validation for vcards in the CardDAV plugin.
+	* Fixed: Issue 213: Workaround for an Evolution bug, that prevented it
+	  from updating events.
+	* Fixed: Issue 211: A time-limit query on a non-relative alarm trigger in
+	  a recurring event could result in an endless loop.
+	* Fixed: All uri fields are now a maximum of 200 characters. The Bynari
+	  outlook plugin used much longer strings so this should improve
+	  compatibility.
+	* Fixed: Added a workaround for a bug in KDE 4.8.2 contact syncing. See
+	  https://bugs.kde.org/show_bug.cgi?id=300047
+	* Fixed: Issue 217: Sabre_DAV_Tree_FileSystem was pretty broken.
+
+1.6.2-stable (2012-04-16)
+	* Fixed: Sabre_VObject_Node::$parent should have been public.
+	* Fixed: Recurrence rules of events are now taken into consideration when
+	  doing time-range queries on alarms.
+	* Fixed: Added a workaround for the fact that php's DateInterval cannot
+	  parse weeks and days at the same time.
+	* Added: Sabre_DAV_Server::$exposeVersion, allowing you to hide SabreDAV's
+	  version number from various outputs.
+	* Fixed: DTSTART values would be incorrect when expanding events.
+	* Fixed: DTSTART and DTEND would be incorrect for expansion of WEEKLY
+	  BYDAY recurrences.
+	* Fixed: Issue 203: A problem with overridden events hitting the exact
+	  date and time of a subsequent event in the recurrence set.
+	* Fixed: There was a problem with recurrence rules, for example the 5th
+	  tuesday of the month, if this day did not exist.
+	* Added: New HTTP status codes from draft-nottingham-http-new-status-04.
+
+1.6.1-stable (2012-03-05)
+	* Added: createFile and put() can now return an ETag.
+	* Added: Sending back an ETag on for operations on CardDAV backends. This
+	  should help with OS X 10.6 Addressbook compatibility.
+	* Fixed: Fixed a bug where an infinite loop could occur in the recurrence
+	  iterator if the recurrence was YEARLY, with a BYMONTH rule, and either
+	  BYDAY or BYMONTHDAY match the first day of the month.
+	* Fixed: Events that are excluded using EXDATE are still counted in the
+	  COUNT= parameter in the RRULE property.
+	* Added: Support for time-range filters on VALARM components.
+	* Fixed: Correctly filtering all-day events.
+	* Fixed: Sending back correct mimetypes from the browser plugin (thanks
+	  Jürgen).
+	* Fixed: Issue 195: Sabre_CardDAV pear package had an incorrect dependency.
+	* Fixed: Calendardata would be destroyed when performing a MOVE request.
+
+1.6.0-stable (2012-02-22)
+	* BC Break: Now requires PHP 5.3
+	* BC Break: Any node that implemented Sabre_DAVACL_IACL must now also
+	  implement the getSupportedPrivilegeSet method. See website for details.
+	* BC Break: Moved functions from Sabre_CalDAV_XMLUtil to
+	  Sabre_VObject_DateTimeParser.
+	* BC Break: The Sabre_DAVACL_IPrincipalCollection now has two new methods:
+	  'searchPrincipals' and 'updatePrincipal'.
+	* BC Break: Sabre_DAV_ILockable is removed and all related per-node
+	  locking functionality.
+	* BC Break: Sabre_DAV_Exception_FileNotFound is now deprecated in favor of
+	  Sabre_DAV_Exception_NotFound. The former will be removed in a later
+	  version.
+	* BC Break: Removed Sabre_CalDAV_ICalendarUtil, use Sabre_VObject instead.
+	* BC Break: Sabre_CalDAV_Server is now deprecated, check out the
+	  documentation on how to setup a caldav server with just
+	  Sabre_DAV_Server.
+	* BC Break: Default Principals PDO backend now needs a new field in the
+	  'principals' table. See the website for details.
+	* Added: Ability to create new calendars and addressbooks from within the
+	  browser plugin.
+	* Added: Browser plugin: icons for various nodes.
+	* Added: Support for FREEBUSY reports!
+	* Added: Support for creating principals with admin-level privileges.
+	* Added: Possibility to let server send out invitation emails on behalf of
+	  CalDAV client, using Sabre_CalDAV_Schedule_IMip.
+	* Changed: beforeCreateFile event now passes data argument by reference.
+	* Changed: The 'propertyMap' property from Sabre_VObject_Reader, must now
+	  be specified in Sabre_VObject_Property::$classMap.
+	* Added: Ability for plugins to tell the ACL plugin which principal
+	  plugins are searchable.
+	* Added: [DAVACL] Per-node overriding of supported privileges. This allows
+	  for custom privileges where needed.
+	* Added: [DAVACL] Public 'principalSearch' method on the DAVACL plugin,
+	  which allows for easy searching for principals, based on their
+	  properties.
+	* Added: Sabre_VObject_Component::getComponents() to return a list of only
+	  components and not properties.
+	* Added: An includes.php file in every sub-package (CalDAV, CardDAV, DAV,
+	  DAVACL, HTTP, VObject) as an alternative to the autoloader. This often
+	  works much faster.
+	* Added: Support for the 'Me card', which allows Addressbook.app users
+	  specify which vcard is their own.
+	* Added: Support for updating principal properties in the DAVACL principal
+	  backends.
+	* Changed: Major refactoring in the calendar-query REPORT code. Should
+	  make things more flexible and correct.
+	* Changed: The calendar-proxy-[read|write] principals will now only appear
+	  in the tree, if they actually exist in the Principal backend. This should
+	  reduce some problems people have been having with this.
+	* Changed: Sabre_VObject_Element_* classes are now renamed to
+	  Sabre_VObject_Property. Old classes are retained for backwards
+	  compatibility, but this will be removed in the future.
+	* Added: Sabre_VObject_FreeBusyGenerator to generate free-busy reports
+	  based on lists of events.
+	* Added: Sabre_VObject_RecurrenceIterator to find all the dates and times
+	  for recurring events.

+	* Added: The contentlength for calendar objects can now be supplied by a
+	  CalDAV backend, allowing for more optimizations.
+	* Fixed: Much faster implementation of Sabre_DAV_URLUtil::encodePath.
+	* Fixed: {DAV:}getcontentlength may now be not specified.
+	* Fixed: Issue 66: Using rawurldecode instead of urldecode to decode paths
+	  from clients. This means that + will now be treated as a literal rather
+	  than a space, and this should improve compatibility with the Windows
+	  built-in client.
+	* Added: Sabre_DAV_Exception_PaymentRequired exception, to emit HTTP 402
+	  status codes.
+	* Added: Some mysql unique constraints to example files.
+	* Fixed: Correctly formatting HTTP dates.
+	* Fixed: Issue 94: Sending back Last-Modified header for 304 responses.
+	* Added: Sabre_VObject_Component_VEvent, Sabre_VObject_Component_VJournal,
+	  Sabre_VObject_Component_VTodo and Sabre_VObject_Component_VCalendar.
+	* Changed: Properties are now also automatically mapped to their
+	  appropriate classes, if they are created using the add() or __set()
+	  methods.
+	* Changed: Cloning VObject objects now clones the entire tree, rather than
+      just the default shallow copy.
+	* Added: Support for recurrence expansion in the CALDAV:calendar-multiget
+	  and CALDAV:calendar-query REPORTS.
+	* Changed: CalDAV PDO backend now sorts calendars based on the internal
+	  'calendarorder' field.
+	* Added: Issue 181: Carddav backends may no optionally not supply the carddata in
+	  getCards, if etag and size are specified. This may speed up certain
+	  requests.
+	* Added: More arguments to beforeWriteContent and beforeCreateFile (see
+	  WritingPlugins wiki document).
+	* Added: Hook for iCalendar validation. This allows us to validate
+	  iCalendar objects when they're uploaded. At the moment we're just
+	  validating syntax.
+	* Added: VObject now support Windows Timezone names correctly (thanks
+	  mrpace2).
+	* Added: If a timezonename could not be detected, we fall back on the
+	  default PHP timezone.
+	* Added: Now a Composer package (thanks willdurand).
+	* Fixed: Support for \N as a newline character in the VObject reader.
+	* Added: afterWriteContent, afterCreateFile and afterUnbind events.
+	* Added: Postgresql example files. Not part of the unittests though, so
+	  use at your own risk.
+	* Fixed: Issue 182: Removed backticks from sql queries, so it will work
+	  with Postgres.
+
+1.5.9-stable (2012-04-16)
+	* Fixed: Issue with parsing timezone identifiers that were surrounded by
+	  quotes. (Fixes emClient compatibility).
+
+1.5.8-stable (2012-02-22)
+	* Fixed: Issue 95: Another timezone parsing issue, this time in
+	  calendar-query.
+
+1.5.7-stable (2012-02-19)
+	* Fixed: VObject properties are now always encoded before components.
+	* Fixed: Sabre_DAVACL had issues with multiple levels of privilege
+	  aggregration.
+	* Changed: Added 'GuessContentType' plugin to fileserver.php example.
+	* Fixed: The Browser plugin will now trigger the correct events when
+	  creating files.
+	* Fixed: The ICSExportPlugin now considers ACL's.
+	* Added: Made it optional to supply carddata from an Addressbook backend
+	  when requesting getCards. This can make some operations much faster, and
+	  could result in much lower memory use.
+	* Fixed: Issue 187: Sabre_DAV_UUIDUtil was missing from includes file.
+	* Fixed: Issue 191: beforeUnlock was triggered twice.
+
+1.5.6-stable (2012-01-07)
+	* Fixed: Issue 174: VObject could break UTF-8 characters.
+	* Fixed: pear package installation issues.
+
+1.5.5-stable (2011-12-16)
+	* Fixed: CalDAV time-range filter workaround for recurring events.
+	* Fixed: Bug in Sabre_DAV_Locks_Backend_File that didn't allow multiple
+	  files to be locked at the same time.
+
+1.5.4-stable (2011-10-28)
+	* Fixed: GuessContentType plugin now supports mixed case file extensions.
+	* Fixed: DATE-TIME encoding was wrong in VObject. (we used 'DATETIME').
+	* Changed: Sending back HTTP 204 after a PUT request on an existing resource
+	  instead of HTTP 200. This should fix Evolution CardDAV client
+	  compatibility.
+	* Fixed: Issue 95: Parsing X-LIC-LOCATION if it's available.
+	* Added: All VObject elements now have a reference to their parent node.
+
+1.5.3-stable (2011-09-28)
+	* Fixed: Sabre_DAV_Collection was missing from the includes file.
+	* Fixed: Issue 152. iOS 1.4.2 apparantly requires HTTP/1.1 200 OK to be in
+	  uppercase.
+	* Fixed: Issue 153: Support for files with mixed newline styles in
+	  Sabre_VObject.
+	* Fixed: Issue 159: Automatically converting any vcard and icalendardata
+	  to UTF-8.
+	* Added: Sabre_DAV_SimpleFile class for easy static file creation.
+	* Added: Issue 158: Support for the CARDDAV:supported-address-data
+	  property.
+
+1.5.2-stable (2011-09-21)
+	* Fixed: carddata and calendardata MySQL fields are now of type
+	  'mediumblob'. 'TEXT' was too small sometimes to hold all the data.
+	* Fixed: {DAV:}supported-report-set is now correctly reporting the reports
+	  for IAddressBook.
+	* Added: Sabre_VObject_Property::add() to add duplicate parameters to
+	  properties.
+	* Added: Issue 151: Sabre_CalDAV_ICalendar and Sabre_CalDAV_ICalendarObject
+	  interfaces.

+1.5.0-stable (2011-08-12)
+	* Added: CardDAV support.
+	* Added: An experimental WebDAV client.
+	* Added: MIME-Directory grouping support in the VObject library. This is
+	  very useful for people attempting to parse vcards.
+	* BC Break: Adding parameters with the VObject libraries now overwrites
+	  the previous parameter, rather than just add it. This makes more sense
+	  for 99% of the cases.
+	* BC Break: lib/Sabre.autoload.php is now removed in favor of
+	  lib/Sabre/autoload.php.
+	* Deprecated: Sabre_DAV_Directory is now deprecated and will be removed in
+	  a future version. Use Sabre_DAV_Collection instead.
+	* Deprecated: Sabre_DAV_SimpleDirectory is now deprecated and will be
+	  removed in a future version. Use Sabre_DAV_SimpleCollection instead.
+	* Fixed: Problem with overriding tablenames for the CalDAV backend.
+	* Added: Clark-notation parser to XML utility.
+	* Added: unset() support to VObject components.
+	* Fixed: Refactored CalDAV property fetching to be faster and simpler.
+	* Added: Central string-matcher for CalDAV and CardDAV plugins.
+	* Added: i;unicode-casemap support
+	* Fixed: VObject bug: wouldn't parse parameters if they weren't specified
+	  in uppercase.
+	* Fixed: VObject bug: Parameters now behave more like Properties.
+	* Fixed: VObject bug: Parameters with no value are now correctly parsed.
+	* Changed: If calendars don't specify which components they allow, 'all'
+	  components are assumed (e.g.: VEVENT, VTODO, VJOURNAL).
+	* Changed: Browser plugin now uses POST variable 'sabreAction' instead of
+	  'action' to reduce the chance of collisions.
+
+1.4.4-stable (2011-07-07)
+	* Fixed: Issue 131: Custom CalDAV backends could break in certain cases.
+	* Added: The option to override the default tablename all PDO backends
+	  use. (Issue 60).
+	* Fixed: Issue 124: 'File' authentication backend now takes realm into
+	  consideration.
+	* Fixed: Sabre_DAV_Property_HrefList now properly deserializes. This
+	  allows users to update the {DAV:}group-member-set property.
+	* Added: Helper functions for DateTime-values in Sabre_VObject package.
+	* Added: VObject library can now automatically map iCalendar properties to
+	  custom classes.
+
+1.4.3-stable (2011-04-25)
+	* Fixed: Issue 123: Added workaround for Windows 7 UNLOCK bug.
+	* Fixed: datatype of lastmodified field in mysql.calendars.sql. Please
+	  change the DATETIME field to an INT to ensure this field will work
+	  correctly.
+	* Change: Sabre_DAV_Property_Principal is now renamed to
+	  Sabre_DAVACL_Property_Principal.
+	* Added: API level support for ACL HTTP method.
+	* Fixed: Bug in serializing {DAV:}acl property.
+	* Added: deserializer for {DAV:}resourcetype property.
+	* Added: deserializer for {DAV:}acl property.
+	* Added: deserializer for {DAV:}principal property.
+
+1.4.2-beta (2011-04-01)
+	* Added: It's not possible to disable listing of nodes that are denied
+	  read access by ACL.
+	* Fixed: Changed a few properties in CalDAV classes from private to
+	  protected.
+	* Fixed: Issue 119: Terrible things could happen when relying on
+	  guessBaseUri, the server was running on the root of the domain and a user
+	  tried to access a file ending in .php. This is a slight BC break.
+	* Fixed: Issue 118: Lock tokens in If headers without a uri should be
+	  treated as the request uri, not 'all relevant uri's.
+	* Fixed: Issue 120: PDO backend was incorrectly fetching too much locks in
+	  cases where there were similar named locked files in a directory.
+
+1.4.1-beta (2011-02-26)
+	* Fixed: Sabre_DAV_Locks_Backend_PDO returned too many locks.
+	* Fixed: Sabre_HTTP_Request::getHeader didn't return Content-Type when
+	  running on apache, so a few workarounds were added.
+	* Change: Slightly changed CalDAV Backend API's, to allow for heavy
+	  optimizations. This is non-bc breaking.
+
+1.4.0-beta (2011-02-12)
+	* Added: Partly RFC3744 ACL support.
+	* Added: Calendar-delegation (caldav-proxy) support.
+	* BC break: In order to fix Issue 99, a new argument had to be added to
+	  Sabre_DAV_Locks_Backend_*::getLocks classes. Consult the classes for
+	  details.
+	* Deprecated: Sabre_DAV_Locks_Backend_FS is now deprecated and will be
+	  removed in a later version. Use PDO or the new File class instead.
+	* Deprecated: The Sabre_CalDAV_ICalendarUtil class is now marked
+	  deprecated, and will be removed in a future version. Please use
+	  Sabre_VObject instead.
+	* Removed: All principal-related functionality has been removed from the
+	  Sabre_DAV_Auth_Plugin, and moved to the Sabre_DAVACL_Plugin.
+	* Added: VObject library, for easy vcard/icalendar parsing using a natural
+	  interface.
+	* Added: Ability to automatically generate full .ics feeds off calendars.
+	  To use: Add the Sabre_CalDAV_ICSExportPlugin, and add ?export to your
+	  calendar url.
+	* Added: Plugins can now specify a pluginname, for easy access using
+	  Sabre_DAV_Server::getPlugin().
+	* Added: beforeGetProperties event.
+	* Added: updateProperties event.
+	* Added: Principal listings and calendar-access can now be done privately,
+	  disallowing users from accessing or modifying other users' data.
+	* Added: You can now pass arrays to the Sabre_DAV_Server constructor. If
+	  it's an array with node-objects, a Root collection will automatically be
+	  created, and the nodes are used as top-level children.
+	* Added: The principal base uri is now customizable. It used to be
+	  hardcoded to 'principals/[user]'.
+	* Added: getSupportedReportSet method in ServerPlugin class. This allows
+	  you to easily specify which reports you're implementing.
+	* Added: A '..' link to the HTML browser.
+	* Fixed: Issue 99: Locks on child elements were ignored when their parent
+	  nodes were deleted.
+	* Fixed: Issue 90: lockdiscovery property and LOCK response now include a
+	  {DAV}lockroot element.
+	* Fixed: Issue 96: support for 'default' collation in CalDAV text-match
+	  filters.
+	* Fixed: Issue 102: Ensuring that copy and move with identical source and
+	  destination uri's fails.
+	* Fixed: Issue 105: Supporting MKCALENDAR with no body.
+	* Fixed: Issue 109: Small fixes in Sabre_HTTP_Util.
+	* Fixed: Issue 111: Properly catching the ownername in a lock (if it's a
+	  string)
+	* Fixed: Sabre_DAV_ObjectTree::nodeExist always returned false for the
+	  root node.
+	* Added: Global way to easily supply new resourcetypes for certain node
+	  classes.
+	* Fixed: Issue 59: Allowing the user to override the authentication realm
+	  in Sabre_CalDAV_Server.
+	* Update: Issue 97: Looser time-range checking if there's a recurrence
+	  rule in an event. This fixes 'missing recurring events'.
+
+1.3.0 (2010-10-14)
+	* Added: childExists method to Sabre_DAV_ICollection. This is an api
+	  break, so if you implement Sabre_DAV_ICollection directly, add the method.
+	* Changed: Almost all HTTP method implementations now take a uri argument,
+	  including events. This allows for internal rerouting of certain calls.
+	  If you have custom plugins, make sure they use this argument. If they
+	  don't, they will likely still work, but it might get in the way of
+	  future changes.
+	* Changed: All getETag methods MUST now surround the etag with
+	  double-quotes. This was a mistake made in all previous SabreDAV
+	  versions. If you don't do this, any If-Match, If-None-Match and If:
+	  headers using Etags will work incorrectly. (Issue 85).
+	* Added: Sabre_DAV_Auth_Backend_AbstractBasic class, which can be used to
+	  easily implement basic authentication.
+	* Removed: Sabre_DAV_PermissionDenied class. Use Sabre_DAV_Forbidden
+	  instead.
+	* Removed: Sabre_DAV_IDirectory interface, use Sabre_DAV_ICollection
+	  instead.
+	* Added: Browser plugin now uses {DAV:}displayname if this property is
+	  available.
+	* Added: Cache layer in the ObjectTree.
+	* Added: Tree classes now have a delete and getChildren method.
+	* Fixed: If-Modified-Since and If-Unmodified-Since would be incorrect if
+	  the date is an exact match.
+	* Fixed: Support for multiple ETags in If-Match and If-None-Match headers.
+	* Fixed: Improved baseUrl handling.
+	* Fixed: Issue 67: Non-seekable stream support in ::put()/::get().
+	* Fixed: Issue 65: Invalid dates are now ignored.
+	* Updated: Refactoring in Sabre_CalDAV to make everything a bit more
+	  ledgable.
+	* Fixed: Issue 88, Issue 89: Fixed compatibility for running SabreDAV on
+	   Windows.
+	* Fixed: Issue 86: Fixed Content-Range top-boundary from 'file size' to
+	  'file size'-1.
+
+1.2.4 (2010-07-13)
+	* Fixed: Issue 62: Guessing baseUrl fails when url contains a
+	  query-string.
+	* Added: Apache configuration sample for CGI/FastCGI setups.
+	* Fixed: Issue 64: Only returning calendar-data when it was actually
+	  requested.
+

+	* Fixed: Issue 57: Supporting quotes around etags in If-Match and
+	  If-None-Match

+	* Fixed: Issue 38, Allowing custom filters to be added to
+	  TemporaryFileFilter.
+	* Fixed: Issue 53, ETags in the If: header were always failing. This
+	  behaviour is now corrected.
+	* Added: Apache Authentication backend, in case authentication through
+	  .htaccess is desired.
+	* Updated: Small improvements to example files.
+
+1.2.0 (2010-05-24)

+	  private.
+
+1.2.0beta3 (2010-05-14)

+	* Updated: CalendarObject validation.
+

+	* Added: Support for If-Range, If-Match, If-None-Match, If-Modified-Since,
+	  If-Unmodified-Since.
+	* Changed: Brand new build system. Functionality is split up between
+	  Sabre, Sabre_HTTP, Sabre_DAV and Sabre_CalDAV packages. In addition to
+	  that a new non-pear package will be created with all this functionality
+	  combined.
+	* Changed: Autoloader moved to Sabre/autoload.php.
+	* Changed: The Allow: header is now more accurate, with appropriate HTTP
+	  methods per uri.
+	* Changed: Now throwing back Sabre_DAV_Exception_MethodNotAllowed on a few
+	  places where Sabre_DAV_Exception_NotImplemented was used.

+
+1.1.1-alpha (2010-03-11)
+	* Added: RFC5689 - Extended MKCOL support.
+	* Fixed: Evolution support for CalDAV.
+	* Fixed: PDO-locks backend was pretty much completely broken. This is
+	  100% unittested now.
+	* Added: support for ctags.
+	* Fixed: Comma's between HTTP methods in 'Allow' method.
+	* Changed: default argument for Sabre_DAV_Locks_Backend_FS. This means a
+	  datadirectory must always be specified from now on.
+	* Changed: Moved Sabre_DAV_Server::parseProps to
+	  Sabre_DAV_XMLUtil::parseProperties.
+	* Changed: Sabre_DAV_IDirectory is now Sabre_DAV_ICollection.

+	* Added: Sabre_DAV_IExtendedCollection.
+	* Added: Many more unittests.
+	* Added: support for calendar-timezone property.
+
+1.1.0-alpha (2010-03-01)
+	* Note: This version is forked from version 1.0.5, so release dates may be
+	  out of order.
+	* Added: CalDAV - RFC 4791
+	* Removed: Sabre_PHP_Exception. PHP has a built-in ErrorException for
+	  this.
+	* Added: PDO authentication backend.
+	* Added: Example sql for auth, caldav, locks for sqlite.
+	* Added: Sabre_DAV_Browser_GuessContentType plugin

+	* Added: Sabre_DAV_Server::getProperties for easy property retrieval
+	* Changed: {DAV:}resourceType defaults to 0
+	* Changed: Any non-null resourceType now gets a / appended to the href
+	  value. Before this was just for {DAV:}collection's, but this is now also
+	  the case for for example {DAV:}principal.
+	* Changed: The Href property class can now optionally create non-relative
+	  uri's.
+	* Changed: Sabre_HTTP_Response now returns false if headers are already

+	* Added: Issue 31: Hiding exception information by default. Can be turned
+	  on with the Sabre_DAV_Server::$debugExceptions property.
+	* Added: Moved autoload from lib/ to lib/Sabre/autoload.php. This is also
+	  the case in the upcoming 1.2.0, so it will improve future compatibility.

+	* Fixed: double namespace declaration in multistatus responses.
+
+1.0.13-stable (2010-03-30)

+	* Updated: Now using pear.sabredav.org pear channel.
+
+1.0.11-stable (2010-03-23)
+	* Non-public release. This release is identical to 1.0.10, but it is used
+	  to test releasing packages to pear.sabredav.org.
+
+1.0.10-stable (2010-03-22)
+	* Fixed: Issue 34: Invalid Lock-Token header response.
+	* Added: Issue 35: Addign SabreDAV version to HTTP OPTIONS responses.
+
+1.0.9-stable (2010-03-19)
+	* Fixed: Issue 27: Entities not being encoded in PROPFIND responses.
+	* Fixed: Issue 29: Added missing TIMEOUT_INFINITE constant.

+	* Fixed: Issue 23: Comma's between methods in Allow header.
+	* Added: Sabre_DAV_ICollection interface, to aid in future compatibility.
+	* Added: Sabre_DAV_Exception_Forbidden exception. This will replace
+	  Sabre_DAV_Exception_PermissionDenied in the future, and can already be
+	  used to ensure future compatibility.
+
+1.0.7-stable (2010-02-24)
+	* Fixed: Issue 19 regression for MS Office
+
+1.0.6-stable (2010-02-23)
+	* Fixed: Issue 19: HEAD requests on Collections
+
+1.0.5-stable (2010-01-22)
+	* Fixed: Fatal error when a malformed url was used for unlocking, in
+	  conjuction with Sabre.autoload.php due to a incorrect filename.
+	* Fixed: Improved unittests and build system
+
+1.0.4-stable (2010-01-11)
+	* Fixed: needed 2 different releases. One for googlecode and one for
+	  pearfarm. This is to retain the old method to install SabreDAV until
+	  pearfarm becomes the standard installation method.
+
+1.0.3-stable (2010-01-11)
+	* Added: RFC4709 support (davmount)
+	* Added: 6 unittests
+	* Added: naturalselection. A tool to keep cache directories below a
+	  specified theshold.
+	* Changed: Now using pearfarm.org channel server.
+
+1.0.1-stable (2009-12-22)
+	* Fixed: Issue 15: typos in examples
+	* Fixed: Minor pear installation issues
+
+1.0.0-stable (2009-11-02)
+	* Added: SimpleDirectory class. This class allows creating static
+	  directory structures with ease.
+	* Changed: Custom complex properties and exceptions now get an instance of
+	  Sabre_DAV_Server as their first argument in serialize()
+	* Changed: Href complex property now prepends server's baseUri
+	* Changed: delete before an overwriting copy/move is now handles by server
+	  class instead of tree classes
+	* Changed: events must now explicitly return false to stop execution.
+	  Before, execution would be stopped by anything loosely evaluating to
+	  false.
+	* Changed: the getPropertiesForPath method now takes a different set of
+	  arguments, and returns a different response. This allows plugin
+	  developers to return statuses for properties other than 200 and 404. The
+	  hrefs are now also always calculated relative to the baseUri, and not
+	  the uri of the request.
+	* Changed: generatePropFindResponse is renamed to generateMultiStatus, and
+	  now takes a list of properties similar to the response of
+	  getPropertiesForPath. This was also needed to improve flexibility for
+	  plugin development.
+	* Changed: Auth plugins are no longer included. They were not yet stable
+	  quality, so they will probably be reintroduced in a later version.
+	* Changed: PROPPATCH also used generateMultiStatus now.
+	* Removed: unknownProperties event. This is replaced by the
+	  afterGetProperties event, which should provide more flexibility.
+	* Fixed: Only calling getSize() on IFile instances in httpHead()
+	* Added: beforeBind event. This is invoked upon file or directory creation
+	* Added: beforeWriteContent event, this is invoked by PUT and LOCK on an
+	  existing resource.
+	* Added: beforeUnbind event. This is invoked right before deletion of any
+	  resource.
+	* Added: afterGetProperties event. This event can be used to make
+	  modifications to property responses.
+	* Added: beforeLock and beforeUnlock events.
+	* Added: afterBind event.
+	* Fixed: Copy and Move could fail in the root directory. This is now
+	  fixed.
+	* Added: Plugins can now be retrieved by their classname. This is useful
+	  for inter-plugin communication.
+	* Added: The Auth backend can now return usernames and user-id's.
+	* Added: The Auth backend got a getUsers method
+	* Added: Sabre_DAV_FSExt_Directory now returns quota info
+
+0.12.1-beta (2009-09-11)
+	* Fixed: UNLOCK bug. Unlock didn't work at all
+
+0.12-beta (2009-09-10)
+	* Updated: Browser plugin now shows multiple {DAV:}resourcetype values
+	  if available.
+	* Added: Experimental PDO backend for Locks Manager
+	* Fixed: Sending Content-Length: 0 for every empty response. This
+	  improves NGinx compatibility.
+	* Fixed: Last modification time is reported in UTC timezone. This improves
+	  Finder compatibility.
+
+0.11-beta (2009-08-11)
+	* Updated: Now in Beta
+	* Updated: Pear package no longer includes docs/ directory. These just
+	  contained rfc's, which are publically available. This reduces the
+	  package from ~800k to ~60k
+	* Added: generatePropfindResponse now takes a baseUri argument
+	* Added: ResourceType property can now contain multiple resourcetypes.
+	* Fixed: Issue 13.
+
+0.10-alpha (2009-08-03)
+	* Added: Plugin to automatically map GET requests to non-files to
+	  PROPFIND (Sabre_DAV_Browser_MapGetToPropFind). This should allow
+	  easier debugging of complicated WebDAV setups.
+	* Added: Sabre_DAV_Property_Href class. For future use.
+	* Added: Ability to choose to use auth-int, auth or both for HTTP Digest
+	  authentication. (Issue 11)
+	* Changed: Made more methods in Sabre_DAV_Server public.
+	* Fixed: TemporaryFileFilter plugin now intercepts HTTP LOCK requests
+	  to non-existent files. (Issue 12)
+	* Added: Central list of defined xml namespace prefixes. This can reduce
+	  Bandwidth and legibility for xml bodies with user-defined namespaces.
+	* Added: now a PEAR-compatible package again, thanks to Michael Gauthier
+	* Changed: moved default copy and move logic from ObjectTree to Tree class
+
+0.9-alpha (2009-07-21)
+	* Changed: Major refactoring, removed most of the logic from the Tree
+	  objects. The Server class now directly works with the INode, IFile
+	  and IDirectory objects. If you created your own Tree objects,
+	  this will most likely break in this release.
+	* Changed: Moved all the Locking logic from the Tree and Server classes
+	  into a separate plugin.
+	* Changed: TemporaryFileFilter is now a plugin.
+	* Added: Comes with an autoloader script. This can be used instead of
+	  the includer script, and is preferred by some people.
+	* Added: AWS Authentication class.
+	* Added: simpleserversetup.py script. This will quickly get a fileserver
+	  up and running.
+	* Added: When subscribing to events, it is now possible to supply a
+	  priority. This is for example needed to ensure that the Authentication
+	  Plugin is used before any other Plugin.
+	* Added: 22 new tests.
+	* Added: Users-manager plugin for .htdigest files. Experimental and
+	  subject to change.
+	* Added: RFC 2324 HTTP 418 status code
+	* Fixed: Exclusive locks could in some cases be picked up as shared locks
+	* Fixed: Digest auth for non-apache servers had a bug (still not actually
+	  tested this well).
+
+0.8-alpha (2009-05-30)
+	* Changed: Renamed all exceptions! This is a compatibility break. Every
+	  Exception now follows Sabre_DAV_Exception_FileNotFound convention
+	  instead of Sabre_DAV_FileNotFoundException.
+	* Added: Browser plugin now allows uploading and creating directories
+	  straight from the browser.
+	* Added: 12 more unittests
+	* Fixed: Locking bug, which became prevalent on Windows Vista.
+	* Fixed: Netdrive support
+	* Fixed: TemporaryFileFilter filtered out too many files. Fixed some
+	  of the regexes.
+	* Fixed: Added README and ChangeLog to package
+
+0.7-alpha (2009-03-29)
+	* Added: System to return complex properties from PROPFIND.
+	* Added: support for {DAV:}supportedlock.
+	* Added: support for {DAV:}lockdiscovery.
+	* Added: 6 new tests.
+	* Added: New plugin system.
+	* Added: Simple HTML directory plugin, for browser access.
+	* Added: Server class now sends back standard pre-condition error xml
+	bodies. This was new since RFC4918.
+	* Added: Sabre_DAV_Tree_Aggregrate, which can 'host' multiple Tree objects
+	into one.
+	* Added: simple basis for HTTP REPORT method. This method is not used yet,
+	but can be used by plugins to add reports.
+	* Changed: ->getSize is only called for files, no longer for collections.
+	r303
+	* Changed: Sabre_DAV_FilterTree is now Sabre_DAV_Tree_Filter
+	* Changed: Sabre_DAV_TemporaryFileFilter is now called
+	Sabre_DAV_Tree_TemporaryFileFilter.
+	* Changed: removed functions (get(/set)HTTPRequest(/Response)) from Server
+	class, and using a public property instead.
+	* Fixed: bug related to parsing proppatch and propfind requests. Didn't
+	show up in most clients, but it needed fixing regardless. (r255)
+	* Fixed: auth-int is now properly supported within HTTP Digest.
+	* Fixed: Using application/xml for a mimetype vs. text/xml as per RFC4918
+	sec 8.2.
+	* Fixed: TemporaryFileFilter now lets through GET's if they actually
+	exist on the backend. (r274)
+	* FIxed: Some methods didn't get passed through in the FilterTree (r283).
+	* Fixed: LockManager is now slightly more complex, Tree classes slightly
+	less. (r287)
+
+0.6-alpha (2009-02-16)
+	* Added: Now uses streams for files, instead of strings.
+	  This means it won't require to hold entire files in memory, which can be
+	  an issue if you're dealing with big files. Note that this breaks
+	  compatibility for put() and createFile methods.
+	* Added: HTTP Digest Authentication helper class.
+	* Added: Support for HTTP Range header
+	* Added: Support for ETags within If: headers
+	* Added: The API can now return ETags and override the default Content-Type
+	* Added: starting with basic framework for unittesting, using PHPUnit.
+	* Added: 49 unittests.
+	* Added: Abstraction for the HTTP request.
+	* Updated: Using Clark Notation for tags in properties. This means tags
+	are serialized as {namespace}tagName instead of namespace#tagName
+	* Fixed: HTTP_BasicAuth class now works as expected.
+	* Fixed: DAV_Server uses / for a default baseUrl.
+	* Fixed: Last modification date is no longer ignored in PROPFIND.
+	* Fixed: PROPFIND now sends back information about the requestUri even
+	  when "Depth: 1" is specified.
+
+0.5-alpha (2009-01-14)
+	* Added: Added a very simple example for implementing a mapping to PHP
+	  file streams. This should allow easy implementation of for example a
+	  WebDAV to FTP proxy.
+	* Added: HTTP Basic Authentication helper class.
+	* Added: Sabre_HTTP_Response class. This centralizes HTTP operations and
+	  will be a start towards the creating of a testing framework.
+	* Updated: Backwards compatibility break: all require_once() statements
+	  are removed
+	  from all the files. It is now recommended to use autoloading of
+	  classes, or just including lib/Sabre.includes.php. This fix was made
+	  to allow easier integration into applications not using this standard
+	  inclusion model.
+	* Updated: Better in-file documentation.
+	* Updated: Sabre_DAV_Tree can now work with Sabre_DAV_LockManager.
+	* Updated: Fixes a shared-lock bug.
+	* Updated: Removed ?> from the bottom of each php file.
+	* Updated: Split up some operations from Sabre_DAV_Server to
+	  Sabre_HTTP_Response.
+	* Fixed: examples are now actually included in the pear package.
+
+0.4-alpha (2008-11-05)
+	* Passes all litmus tests!
+	* Added: more examples
+	* Added: Custom property support
+	* Added: Shared lock support
+	* Added: Depth support to locks
+	* Added: Locking on unmapped urls (non-existent nodes)
+	* Fixed: Advertising as WebDAV class 3 support
+
+0.3-alpha (2008-06-29)
+	* Fully working in MS Windows clients.
+	* Added: temporary file filter: support for smultron files.
+	* Added: Phing build scripts
+	* Added: PEAR package
+	* Fixed: MOVE bug identified using finder.
+	* Fixed: Using gzuncompress instead of gzdecode in the temporary file
+	  filter. This seems more common.
+
+0.2-alpha (2008-05-27)
+	* Somewhat working in Windows clients
+	* Added: Working PROPPATCH method (doesn't support custom properties yet)
+	* Added: Temporary filename handling system
+	* Added: Sabre_DAV_IQuota to return quota information
+	* Added: PROPFIND now reads the request body and only supplies the
+	  requested properties
+
+0.1-alpha (2008-04-04)
+	* First release!
+	* Passes litmus: basic, http and copymove test.
+	* Fully working in Finder and DavFSv2

+     * iCalendar component types (VTODO, VEVENT).
+     *
+     * This method should just return a list of (relative) urls that match this

+     * Note that it is extremely likely that getCalendarObject for every path
+     * returned from this method will be called almost immediately after. You

+     *
+     * This method provides a default implementation, which parses *all* the

+     *
+     * This default may well be good enough for personal use, and calendars
+     * that aren't very large. But if you anticipate high usage, big calendars
+     * or high loads, you are strongly adviced to optimize certain paths.
+     *
+     * The best way to do so is override this method and to optimize
+     * specifically for 'common filters'.
+     *
+     * Requests that are extremely common are:
+     *   * requests for just VEVENTS
+     *   * requests for just VTODO
+     *   * requests with a time-range-filter on either VEVENT or VTODO.

+     * handle every possible situation and just rely on the (relatively
+     * easy to use) CalendarQueryValidator to handle the rest.
+     *
+     * Note that especially time-range-filters may be difficult to parse. A
+     * time-range filter specified on a VEVENT must for instance also handle
+     * recurrence rules correctly.
+     * A good example of how to interprete all these filters can also simply
+     * be found in \OldSabre\CalDAV\CalendarQueryFilter. This class is as correct

+     * returned from this method will be called almost immediately after. You
+     * may want to anticipate this to speed up these requests.

+     * This method provides a default implementation, which parses *all* the

+     *
+     * This default may well be good enough for personal use, and calendars
+     * that aren't very large. But if you anticipate high usage, big calendars
+     * or high loads, you are strongly adviced to optimize certain paths.

+     *   * requests for just VEVENTS
+     *   * requests for just VTODO
+     *   * requests with a time-range-filter on a VEVENT.

+     * ..and combinations of these requests. It may not be worth it to try to
+     * handle every possible situation and just rely on the (relatively
+     * easy to use) CalendarQueryValidator to handle the rest.
+     *
+     * Note that especially time-range-filters may be difficult to parse. A
+     * time-range filter specified on a VEVENT must for instance also handle
+     * recurrence rules correctly.
+     * A good example of how to interprete all these filters can also simply
+     * be found in \OldSabre\CalDAV\CalendarQueryFilter. This class is as correct

+/**
+ * Adds support for sharing features to a CalDAV server.
+ *
+ * Note: This feature is experimental, and may change in between different
+ * SabreDAV versions.
+ *
+ * Early warning: Currently SabreDAV provides no implementation for this. This
+ * is, because in it's current state there is no elegant way to do this.
+ * The problem lies in the fact that a real CalDAV server with sharing support
+ * would first need email support (with invite notifications), and really also
+ * a browser-frontend that allows people to accept or reject these shares.
+ *
+ * In addition, the CalDAV backends are currently kept as independent as
+ * possible, and should not be aware of principals, email addresses or
+ * accounts.
+ *
+ * Adding an implementation for Sharing to standard-sabredav would contradict
+ * these goals, so for this reason this is currently not implemented, although
+ * it may very well in the future; but probably not before SabreDAV 2.0.
+ *
+ * The interface works however, so if you implement all this, and do it
+ * correctly sharing _will_ work. It's not particularly easy, and I _urge you_
+ * to make yourself acquainted with the following document first:
+ *
+ * https://trac.calendarserver.org/browser/CalendarServer/trunk/doc/Extensions/caldav-sharing.txt
+ *
+ * An overview
+ * ===========
+ *
+ * Implementing this interface will allow a user to share his or her calendars
+ * to other users. Effectively, when a calendar is shared the calendar will
+ * show up in both the Sharer's and Sharee's calendar-home root.
+ * This interface adds a few methods that ensure that this happens, and there
+ * are also a number of new requirements in the base-class you must now follow.
+ *
+ *
+ * How it works
+ * ============
+ *
+ * When a user shares a calendar, the updateShares() method will be called with
+ * a list of sharees that are now added, and a list of sharees that have been
+ * removed.
+ * Removal is instant, but when a sharee is added the sharee first gets a
+ * chance to accept or reject the invitation for a share.
+ *
+ * After a share is accepted, the calendar will be returned from
+ * getUserCalendars for both the sharer, and the sharee.
+ *
+ * If the sharee deletes the calendar, only their share gets deleted. When the
+ * owner deletes a calendar, it will be removed for everybody.
+ *
+ *
+ * Notifications
+ * =============
+ *
+ * During all these sharing operations, a lot of notifications are sent back
+ * and forward.
+ *
+ * Whenever the list of sharees for a calendar has been changed (they have been
+ * added, removed or modified) all sharees should get a notification for this
+ * change.
+ * This notification is always represented by:
+ *
+ * OldSabre\CalDAV\Notifications\Notification\Invite
+ *
+ * In the case of an invite, the sharee may reply with an 'accept' or
+ * 'decline'. These are always represented by:
+ *
+ * OldSabre\CalDAV\Notifications\Notification\Invite
+ *
+ *
+ * Calendar access by sharees
+ * ==========================
+ *
+ * As mentioned earlier, shared calendars must now also be returned for
+ * getCalendarsForUser for sharees. A few things change though.
+ *
+ * The following properties must be specified:
+ *
+ * 1. {http://calendarserver.org/ns/}shared-url
+ *
+ * This property MUST contain the url to the original calendar, that is.. the
+ * path to the calendar from the owner.
+ *
+ * 2. {http://sabredav.org/ns}owner-principal
+ *
+ * This is a url to to the principal who is sharing the calendar.
+ *
+ * 3. {http://sabredav.org/ns}read-only
+ *
+ * This should be either 0 or 1, depending on if the user has read-only or
+ * read-write access to the calendar.
+ *
+ * Only when this is done, the calendar will correctly be marked as a calendar
+ * that's shared to him, thus allowing clients to display the correct interface
+ * and ACL enforcement.
+ *
+ * If a sharee deletes their calendar, only their instance of the calendar
+ * should be deleted, the original should still exists.
+ * Pretty much any 'dead' WebDAV properties on these shared calendars should be
+ * specific to a user. This means that if the displayname is changed by a
+ * sharee, the original is not affected. This is also true for:
+ *   * The description
+ *   * The color
+ *   * The order
+ *   * And any other dead properties.
+ *
+ * Properties like a ctag should not be different for multiple instances of the
+ * calendar.
+ *
+ * Lastly, objects *within* calendars should also have user-specific data. The
+ * two things that are user-specific are:
+ *   * VALARM objects
+ *   * The TRANSP property
+ *
+ * This _also_ implies that if a VALARM is deleted by a sharee for some event,
+ * this has no effect on the original VALARM.
+ *
+ * Understandably, the this last requirement is one of the hardest.
+ * Realisticly, I can see people ignoring this part of the spec, but that could
+ * cause a different set of issues.
+ *
+ *
+ * Publishing
+ * ==========
+ *
+ * When a user publishes a url, the server should generate a 'publish url'.
+ * This is a read-only url, anybody can use to consume the calendar feed.
+ *
+ * Calendars are in one of two states:
+ *   * published
+ *   * unpublished
+ *
+ * If a calendar is published, the following property should be returned
+ * for each calendar in getCalendarsForPrincipal.
+ *
+ * {http://calendarserver.org/ns/}publish-url
+ *
+ * This element should contain a {DAV:}href element, which points to the
+ * public url that does not require authentication. Unlike every other href,
+ * this url must be absolute.
+ *
+ * Ideally, the following property is always returned
+ *
+ * {http://calendarserver.org/ns/}pre-publish-url
+ *
+ * This property should contain the url that the calendar _would_ have, if it
+ * were to be published. iCal uses this to display the url, before the user
+ * will actually publish it.
+ *
+ *
+ * Selectively disabling publish or share feature
+ * ==============================================
+ *
+ * If OldSabre\CalDAV\Property\AllowedSharingModes is returned from
+ * getCalendarsByUser, this allows the server to specify whether either sharing,
+ * or publishing is supported.
+ *
+ * This allows a client to determine in advance which features are available,
+ * and update the interface appropriately. If this property is not returned by
+ * the backend, the SharingPlugin automatically injects it and assumes both
+ * features are available.

+
+            The symptom of this problem is that Finder sends files to the

+
+            If we don't do anything, the user might think they are uploading

+
+            The reason Finder uses Chunked, is because it thinks the files
+            might change as it's being uploaded, and therefore the
+            Content-Length can vary.
+
+            Instead it sends the X-Expected-Entity-Length header with the size

+2.1.0-stable (2013-06-17)
+	* This version is fully backwards compatible with 2.0.*. However, it
+	  contains a few new API's that mimic the VObject 3 API. This allows it to
+	  be used a 'bridge' version.
+	  Specifically, this new version exists so SabreDAV 1.7 and 1.8 can run with
+	  both the 2 and 3 versions of this library.
+	* Added: Property\DateTime::hasTime().
+	* Added: Property\MultiDateTime::hasTime().
+	* Added: Property::getValue().
+	* Added: Document class.
+	* Added: Document::createComponent and Document::createProperty.
+	* Added: Parameter::getValue().
+
+
+2.0.7-stable (2013-03-05)
+	* Fixed: Microsoft re-uses their magic numbers for different timezones,
+	  specifically id 2 for both Sarajevo and Lisbon). A workaround was added
+	  to deal with this.
+
+2.0.6-stable (2013-02-17)
+	* Fixed: The reader now properly parses parameters without a value.
+
+2.0.5-stable (2012-11-05)
+	* Fixed: The FreeBusyGenerator is now properly using the factory methods
+	  for creation of components and properties.
+
+2.0.4-stable (2012-11-02)
+	* Added: Known Lotus Notes / Domino timezone id's.
+
+2.0.3-stable (2012-10-29)
+	* Added: Support for 'GMT+????' format in TZID's.
+	* Added: Support for formats like SystemV/EST5EDT in TZID's.
+	* Fixed: RecurrenceIterator now repairs recurrence rules where UNTIL < DTSTART.
+	* Added: Support for BYHOUR in FREQ=DAILY (@hollodk).
+	* Added: Support for BYHOUR and BYDAY in FREQ=WEEKLY.
+
+2.0.2-stable (2012-10-06)
+	* Added: includes.php file, to load the entire library in one go.
+	* Fixed: A problem with determining alarm triggers for TODO's.
+
+2.0.1-stable (2012-09-22)
+	* Removed: Element class. It wasn't used.
+	* Added: Basic validation and repair methods for broken input data.
+	* Fixed: RecurrenceIterator could infinitely loop when an INTERVAL of 0
+	  was specified.
+	* Added: A cli script that can validate and automatically repair vcards
+	  and iCalendar objects.
+	* Added: A new 'Compound' property, that can automatically split up parts
+	  for properties such as N, ADR, ORG and CATEGORIES.
+	* Added: Splitter classes, that can split up large objects (such as exports)
+	  into individual objects (thanks @DominikTO and @armin-hackmann).
+	* Added: VFREEBUSY component, which allows easily checking wether
+	  timeslots are available.
+	* Added: The Reader class now has a 'FORGIVING' option, which allows it to
+	  parse properties with incorrect characters in the name (at this time, it
+	  just allows underscores).
+	* Added: Also added the 'IGNORE_INVALID_LINES' option, to completely
+	  disregard any invalid lines.
+	* Fixed: A bug in Windows timezone-id mappings for times created in

+SabreTooth VObject library
+==========================
+
+[![Build Status](https://secure.travis-ci.org/fruux/sabre-vobject.png?branch=master)](http://travis-ci.org/fruux/sabre-vobject)
+
+The VObject library allows you to easily parse and manipulate [iCalendar](https://tools.ietf.org/html/rfc5545)
+and [vCard](https://tools.ietf.org/html/rfc6350) objects using PHP.
+The goal of the VObject library is to create a very complete library, with an easy to use API.
+
+This project is a spin-off from [SabreDAV](http://code.google.com/p/sabredav/), where it has
+been used for several years. The VObject library has 100% unittest coverage.
+
+Installation
+------------
+
+VObject requires PHP 5.3, and should be installed using composer.
+The general composer instructions can be found on the [composer website](http://getcomposer.org/doc/00-intro.md composer website).
+
+After that, just declare the vobject dependency as follows:
+
+```
+"require" : {
+    "sabre/vobject" : "2.0.*"
+}
+```
+
+Then, run `composer.phar update` and you should be good.
+
+Usage
+-----
+
+### Parsing
+
+For our example, we will be using the following vcard:
+
+```
+BEGIN:VCARD
+VERSION:3.0
+PRODID:-//Sabre//Sabre VObject 2.0//EN
+N:Planck;Max;;;
+FN:Max Planck
+EMAIL;TYPE=WORK:mplanck@example.org
+item1.TEL;TYPE=CELL:(+49)3144435678
+item1.X-ABLabel:Private cell
+item2.TEL;TYPE=WORK:(+49)5554564744
+item2.X-ABLabel:Work
+END:VCARD
+```
+
+
+If we want to just print out Max' full name, you can just use property access:
+
+
+```php
+use OldSabre\VObject;
+
+$card = VObject\Reader::read($data);
+echo $card->FN;
+```
+
+### Changing properties
+
+Creating properties is pretty similar. If we like to add his birthday, we just
+set the property:
+
+```php
+$card->BDAY = '1858-04-23';
+```
+
+Note that in the previous example, we're actually updating any existing BDAY that
+may already exist. If we want to add a new property, without overwriting the previous
+we can do this with the `add` method.
+
+```php
+$card->add('EMAIL','max@example.org');
+```
+
+### Parameters
+
+If we want to also specify that this is max' home email addresses, we can do this with
+a third parameter:
+
+```
+$card->add('EMAIL', 'max@example'org', array('type' => 'HOME'));
+```
+
+If we want to read out all the email addresses and their type, this would look something
+like this:
+
+```
+foreach($card->EMAIL as $email) {
+
+    echo $email['TYPE'], ' - ', $email;
+
+}
+```
+
+### Groups
+
+In our example, you can see that the TEL properties are prefixed. These are 'groups' and
+allow you to group multiple related properties together. The group can be any user-defined
+name.
+
+This particular example as generated by the OS X addressbook, which uses the `X-ABLabel`
+to allow the user to specify custom labels for properties. OS X addressbook uses groups
+to tie the label to the property.
+
+The VObject library simply ignores the group if you don't specify it, so this will work:
+
+```php
+foreach($card->TEL as $tel) {
+    echo $tel, "\n";
+}
+```
+
+But if you would like to target a specific group + property, this is possible too:
+
+```php
+echo $card->{'ITEM1.TEL'};
+```
+
+So if you would like to show all the phone numbers, along with their custom label, the
+following syntax is used:
+
+```php
+foreach($card->TEL as $tel) {
+
+    echo $card->{$tel->group . '.X-ABLABEL'}, ": ";
+    echo $tel, "\n";
+
+}
+```
+
+### Serializing / Saving
+
+If you want to generate your updated VObject, you can simply call the serialize() method.
+
+```php
+echo $card->serialize();
+```
+
+### Components
+
+iCalendar, unlike vCards always have sub-components. Where vCards are often just a flat
+list, iCalendar objects tend to have a tree-like structure. For the following paragraphs,
+we will use the following object as the example:
+
+```
+BEGIN:VCALENDAR
+VERSION:2.0
+PRODID:-//Sabre//Sabre VObject 2.0//EN
+BEGIN:VEVENT
+SUMMARY:Curiosity landing
+DTSTART:20120806T051439Z
+LOCATION:Mars
+END:VEVENT
+END:VCALENDAR
+```
+
+Since events, tasks and journals are always in a sub component, this is also how we
+access them.
+
+```php
+use OldSabre\VObject;
+
+$calendar = VObject\Reader::read($data);
+echo $calendar->VEVENT->SUMMARY;
+```
+
+Adding components to a calendar is done with a factory method:
+
+```php
+$event = VObject\Component::create('VEVENT');
+$calendar->add($event);
+
+$event->SUMMARY = 'Curiosity launch';
+$event->DTSTART = '20111126T150202Z';
+$event->LOCATION = 'Cape Carnival';
+```
+
+By the way.. cloning also works as expected, as the entire structure is cloned along with it:
+
+```php
+$clonedEvent = clone $calendar->VEVENT[0];
+$calendar->add($clonedEvent);
+```
+
+### Date and time handling
+
+If you ever had to deal with iCalendar timezones, you know it can be complicated.
+The way timezones are specified is flawed, which is something I may write an essay about some
+day. VObject does its best to determine the correct timezone. Many standard formats
+have been tested and verified, and special code has been implemented for special-casing
+microsoft generated timezone information, and others.
+
+To get a real php `DateTime` object, you can request this as follows:
+
+```php
+$event = $calendar->VEVENT;
+$start = $event->DTSTART->getDateTime();
+echo $start->format(\DateTime::W3C);
+```
+
+To set the property with a DateTime object, you can use the following syntax:
+
+```php
+$dateTime = new \DateTime('2012-08-07 23:53:00', new DateTimeZone('Europe/Amsterdam'));
+$event->DTSTART->setDateTime($dateTime, VObject\Property\DateTime::DATE);
+```
+
+The second argument specifies the type of date you're setting. The following three
+options exist:
+
+1. `LOCAL` This is a floating time, with no timezone information. This basically specifies that the event happens in whatever the timezone's currently in. This would be encoded as `DTSTART;VALUE=DATE-TIME:20120807235300`
+2. `UTC` This specifies that the time should be encoded as a UTC time. This is encoded as `DTSTART;VALUE=DATE-TIME:20120807205300Z`. Note the extra Z and the fact that it's two hours 'earlier'.
+3. `LOCALTZ` specifies that it's supposed to be encoded in its local timezone. For example `DTSTART;VALUE=DATE-TIME;TZID=Europe/Amsterdam:20120807235300`.
+4. `DATE` This is a date-only, and does not contain the time. In this case this would be encoded as `DTSTART;VALUE=DATE:20120807`.
+
+A few important notes:
+
+* When a `TZID` is specified, there should also be a matching `VTIMEZONE` object with all the timezone information. VObject cannot currently automatically embed this. However, in reality other clients seem to do fine without this information. Yet, for completeness, this will be added in the future.
+* As mentioned, the timezone-determination process may sometimes fail. Report any issues you find, and I'll be quick to add workarounds!
+
+### Recurrence rules
+
+Recurrence rules allow events to recur, for example for a weekly meeting, or an anniversary.
+This is done with the `RRULE` property. The `RRULE` property allows for a LOT of different
+rules. VObject only implements the ones that actually appear in calendar software.
+
+To read more about `RRULE` and all the options, check out [RFC5545](https://tools.ietf.org/html/rfc5545#section-3.8.5).
+VObject supports the following options:
+
+1. `UNTIL` for an end date.
+2. `INTERVAL` for for example "every 2 days".
+3. `COUNT` to stop recurring after x items.
+4. `FREQ=DAILY` to recur every day, and `BYDAY` to limit it to certain days.
+5. `FREQ=WEEKLY` to recur every week, `BYDAY` to expand this to multiple weekdays in every week and `WKST` to specify on which day the week starts.
+6. `FREQ=MONTHLY` to recur every month, `BYMONTHDAY` to expand this to certain days in a month, `BYDAY` to expand it to certain weekdays occuring in a month, and `BYSETPOS` to limit the last two expansions.
+7. `FREQ=YEARLY` to recur every year, `BYMONTH` to expand that to certain months in a year, and `BYDAY` and `BYWEEKDAY` to expand the `BYMONTH` rule even further.
+
+VObject supports the `EXDATE` property for exclusions, but not yet the `RDATE` and `EXRULE` 
+properties. If you're interested in this, please file a github issue, as this will put it
+on my radar.
+
+This is a bit of a complex subject to go in excruciating detail. The
+[RFC](https://tools.ietf.org/html/rfc5545#section-3.8.5) has a lot of examples though.
+
+The hard part is not to write the RRULE, it is to expand them. The most complex and
+hard-to-read code is hidden in this component. Dragons be here.
+
+So, if we have a meeting every 2nd monday of the month, this would be specified as such:
+
+```
+BEGIN:VCALENDAR
+VERSION:2.0
+PRODID:-//Sabre//Sabre VObject 2.0//EN
+BEGIN:VEVENT
+UID:1102c450-e0d7-11e1-9b23-0800200c9a66
+DTSTART:20120109T140000Z
+RRULE:FREQ=MONTHLY;BYDAY=MO;BYSETPOS=2
+END:VEVENT
+END:VCALENDAR
+```
+
+Note that normally it's not allowed to indent the object like this, but it does make
+it easier to read. This is also the first time I added in a UID, which is required
+for all VEVENT, VTODO and VJOURNAL objects!
+
+To figure out all the meetings for this year, we can use the following syntax:
+
+```php
+use OldSabre\VObject;
+
+$calendar = VObject\Reader::read($data);
+$calendar->expand(new DateTime('2012-01-01'), new DateTime('2012-12-31'));
+```
+
+What the expand method does, is look at its inner events, and expand the recurring
+rule. Our calendar now contains 12 events. The first will have its RRULE stripped,
+and every subsequent VEVENT has the correct meeting date and a `RECURRENCE-ID` set.
+
+This results in something like this:
+
+```
+BEGIN:VCALENDAR
+  VERSION:2.0
+  PRODID:-//Sabre//Sabre VObject 2.0//EN
+  BEGIN:VEVENT
+    UID:1102c450-e0d7-11e1-9b23-0800200c9a66
+    DTSTART:20120109T140000Z
+  END:VEVENT
+  BEGIN:VEVENT
+    UID:1102c450-e0d7-11e1-9b23-0800200c9a66
+    RECURRENCE-ID:20120213T140000Z
+    DTSTART:20120213T140000Z
+  END:VEVENT
+  BEGIN:VEVENT
+    UID:1102c450-e0d7-11e1-9b23-0800200c9a66
+    RECURRENCE-ID:20120312T140000Z
+    DTSTART:20120312T140000Z
+  END:VEVENT
+  ..etc..
+END:VCALENDAR
+```
+
+To show the list of dates, we would do this as such:
+
+```php
+foreach($calendar->VEVENT as $event) {
+    echo $event->DTSTART->getDateTime()->format(\DateTime::ATOM);
+}
+```
+
+In a recurring event, single instances can also be overriden. VObject also takes these
+into consideration. The reason we needed to specify a start and end-date, is because
+some recurrence rules can be 'never ending'.
+
+You should make sure you pick a sane date-range. Because if you pick a 50 year
+time-range, for a daily recurring event; this would result in over 18K objects.
+
+Free-busy report generation
+---------------------------
+
+Some calendaring software can make use of FREEBUSY reports to show when people are
+available.
+
+You can automatically generate these reports from calendars using the `FreeBusyGenerator`.
+
+Example based on our last event:
+
+```php
+// We're giving it the calendar object. It's also possible to specify multiple objects,
+// by setting them as an array.
+//
+// We must also specify a start and end date, because recurring events are expanded.
+$fbGenerator = new VObject\FreeBusyGenerator(
+    new DateTime('2012-01-01'),
+    new DateTime('2012-12-31'),
+    $calendar
+);
+
+// Grabbing the report
+$freebusy = $fbGenerator->result();
+
+// The freebusy report is another VCALENDAR object, so we can serialize it as usual:
+echo $freebusy->serialize();
+```
+
+The output of this script will look like this:
+
+```
+BEGIN:VCALENDAR
+VERSION:2.0
+PRODID:-//Sabre//Sabre VObject 2.0//EN
+CALSCALE:GREGORIAN
+BEGIN:VFREEBUSY
+DTSTART;VALUE=DATE-TIME:20111231T230000Z

+ * This class is used to determine new for a recurring event, when the next
+ * events occur.
+ *
+ * This iterator may loop infinitely in the future, therefore it is important
+ * that if you use this class, you set hard limits for the amount of iterations
+ * you want to handle.
+ *
+ * Note that currently there is not full support for the entire iCalendar
+ * specification, as it's very complex and contains a lot of permutations
+ * that's not yet used very often in software.
+ *
+ * For the focus has been on features as they actually appear in Calendaring
+ * software, but this may well get expanded as needed / on demand
+ *
+ * The following RRULE properties are supported
+ *   * UNTIL
+ *   * INTERVAL
+ *   * COUNT
+ *   * FREQ=DAILY
+ *     * BYDAY
+ *     * BYHOUR
+ *   * FREQ=WEEKLY
+ *     * BYDAY
+ *     * BYHOUR
+ *     * WKST
+ *   * FREQ=MONTHLY
+ *     * BYMONTHDAY
+ *     * BYDAY
+ *     * BYSETPOS
+ *   * FREQ=YEARLY
+ *     * BYMONTH
+ *     * BYMONTHDAY (only if BYMONTH is also set)
+ *     * BYDAY (only if BYMONTH is also set)
+ *
+ * Anything beyond this is 'undefined', which means that it may get ignored, or
+ * you may get unexpected results. The effect is that in some applications the
+ * specified recurrence may look incorrect, or is missing.
