* Some obsolete/stale library highlighting refinements
* Column width issues resolved
* Dynamic UID column sizing improved
* Discard stale information from Disk and Network I/O meters
* Refined Linux kernel thread detection
* Reworked process state handling
* New CCGROUP column showing abbreviated cgroup name
* New OFFSET column in the list of open files screen

What's new in version 3.1.1

* Update license headers to explicitly say GPLv2+
* Document minimum version for libcap (thanks to James Brown)
* Fix mouse wheel collision with autogroups nice adjustment
* Adjust Makefile.am macro definitions for older automake versions
* Ensure consistent reporting of MemoryMeter 'used' memory
* Report hugepage memory as real and used memory (as before)
* Handle procExeDeleted, usesDeletedLib without mergedCommandline mode
* Validate meter configuration before proceeding beyond htoprc parsing
* Properly release memory on partially read configuration
* Handle interrupted sampling from within libpcp PDU transfers
* On Linux, provide O_PATH value if not defined
* On Linux, always compute procExeDeleted if already set
* Workaround for Rosetta 2 on Darwin (thanks to Alexander Momchilov)
* Fix FreeBSD cmdline memory leak in Process_updateCmdline, and
* Plug a Disk I/O meter memory leak on FreeBSD (thanks to Ximalas)

What's new in version 3.1.0

* Updated COPYING file to remove the PLPA exemption (appendix 2)
  With this change the license is now GPLv2 without any additional wording.
* Improved default sort ordering
  Note for users: This may lead to an inverted sort order on startup of
  htop 3.1.0 compared to previous versions.
  This is due to what is stored in your htoprc file. Solution: Press I
  (to invert sort order).
  This changed setting will be saved by htop on exit as long as it can
  write to your htoprc file.
* The compile-time option to cater specifically for running htop as
  setuid has been removed
* Add read-only option
  This allows htop to be run in an non-intrusive fashion where it acts only
  as a process viewer disabling all functions to manipulate system state.
  Note: This is not a security feature!
* Move the code for handling the command line formatting related tasks
  to be shared across all platforms
  This means important features like stale binary/library highlighting
  can now be available on all supported platforms.
* Make the EXE and COMM columns available on all platforms
  All supported platforms have the name of the executable (EXE) and a
  self-chosen thread/command name (COMM) available one way or the other.
  Moving this column to be handled as a platform-independently available
  information simplifies the markup of the command line.
* Introduce configuration file versioning and config_reader_min_version
  Starting with this version the configuration file contains a version
  identifying the minimum version of the configuration parser needed to
  fully understand the configuration file format.
  Old configuration file formats are automatically upgraded when
  saving the config file (htoprc).
* Make the configuration parser friendlier to users (thanks to Bart Bakker)
  With this change only settings that cannot be parsed properly are
  reset to their defaults.
* Improve default display for systems with many CPUs
* Add the process ELAPSED time column
* Improve the process STATE column sorting
* Reworked handling resize and redrawing of the UI
* Fixed an issue where the LED meter mode could overflow allotted space
* Allow text mode Meters to span empty neighbors to the right
* Rescale graph meters when value of total changes
  (thanks to Michael Schönitzer)
* Update generic process field display
  Usually "uninteresting" values in columns like 1 thread, nice value
  of 0, CPU and memory of 0%, idle/sleeping state, etc. are shown with
  reduced intensity (dark grey)
* Option and key ("*") to collapse / expand all branches under PID 1
  (and PID 2 if kernel threads are shown) (thanks to Krishna Chaitanya)
* Keep following a process when inverting the sort order, displaying
  the help screen or hiding/unhiding userland threads.
  If a thread is currently selected the selection is updated to point
  to the thread's parent process. (thanks to Gonzalo, et.al.)
* Reorder process scanning to be performed before updating the display
  of the meters in the header
* Always check the user for a process for any changes.
  This affects multiple platforms that previously didn't correctly handle
  the user field for a process to change at runtime (e.g. due to seteuid
  or similar syscalls).
* Disable mouse option when support is unavailable
* Support curses libraries without ncurses mouse support
  (thanks to Santhosh Raju)
* Support offline and hot-swapping of CPUs on all platforms
* Fix the CPU Meter for machines with more than 256 CPUs
* Supplemented the "show updated/deleted executables" feature (red basename)
  to indicate when linked libraries were updated (yellow basename)
* Apply the stale binary highlighting for the EXE column in addition to
  the command line field
* Add new combined Memory and Swap meter
* Implement bar and graph mode for NetworkIO Meter
  (thanks to Michael F. Schönitzer)
* Rework TTY column to be more consistent across platforms
* Make the CWD column generally available on all platforms
  (thanks to Santhosh Raju et. al.)
* Add Performance Co-Pilot (PCP) platform support
  This is added via a separate pcp-htop(1) binary which provides remote host
  analysis, new Meters for any PCP metric and new Columns for any PCP process
  metric - see the pcp-htop(5) man page for further details.
  (thanks to Sohaib Mohamed)
* Add Linux columns and key bindings for process autogroup identifier
  and nice value
* Change available and used memory reporting on Linux to be based on
  MemAvailable (Kernel 3.14+) (thanks to Chris Cheney and Tomas Wido)
* Add a new SysArchMeter showing kernel and platform information
  (thanks to ahgamut)
* Linux memory usage explicitly treats tmpfs memory usage as shared memory
  This is to make memory used by tmpfs visible as this cannot be freed
  unlike normal filesystem cache data.
* Exclude zram devices when calculating DiskIO on Linux
* Use PATH lookup for systemctl in systemd meter (thanks to Scott Olson)
* Add native platform support for NetBSD
  This allows htop to run on NetBSD without the need for active Linux
  emulation of the procfs filesystem.
  (thanks to Santhosh Raju and Nia Alarie)
* Add NetworkIO, DiskIO, CPU frequency, and battery meter support on NetBSD
  (thanks to Nia Alarie)
* Fix NetBSD display of in-use and cached memory (thanks to Nia Alarie)
* Rework NetBSD CPU and memory accounting (thanks to Santhosh Raju)
* Fix NetBSD accounting of user and kernel threads (thanks to Santhosh Raju)
* Initial work to allow building with default libcurses on NetBSD
  (thanks to Santhosh Raju)
* FreeBSD updates - implement process majflt and processor column values
* Add FreeBSD support for CPU frequency and temperature
* Fixes and cleanups for ZFS Meters and metrics
* Correctly color the ZFS ARC ratio (thanks to Ross Williams)
* Bugfixes related to CPU time display/calculations for darwin on M1 systems
  (thanks to Alexander Momchilov)
* Harmonize the handling of multiple batteries across different platforms.
  The system is now considered to run on AC if at least one power supply
  marked as AC is found in the system.
  Battery capacity is summed up over all batteries found.
  This also changes the old behavior that batteries reported by the
  system after the first AC adapter where sometimes ignored.
* Correctly handle multiple batteries on Darwin.
  Resolves a possible memory leak on systems with multiple batteries.
* Handle Linux Shmem being part of Cached in the MemoryMeter
* Add SwapCached to the Linux swap meter (thanks to David Zarzycki)
* Convert process time to days if applicable (thanks to David Zarzycki)
* Always show the number of threads in the TaskMeter, even when threads
  are not shown in the process list
* Fix Linux --drop-capabilities option handling
* Correctly detect failure to initialize Linux boottime
* Overhaul the Linux memory fields to partition them like free(1) now does
* Improve the Linux process I/O column values
* Rework the libsensors parsing on Linux
* Update the MemoryMeter to display shared memory
* Update OpenBSD platform - implement additional columns, scan LWP,
  proper markup for STATE, show CPU frequency
* Fix the tree view on OpenBSD when hiding kernel threads
* Remove old InfoScreen lines before re-scanning (thanks to Øystein Hiåsen)
