-What's new in version 3.1.0 (not released yet)
+What's new in version 3.1.0
-* Change available / used memory reporting on Linux to be based on
- MemAvailable (Kernel 3.14+) (thanks to Chris Cheney and Tomas Wido)
+
+* 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 3.0.6 compared to previous versions. This is due to what is stored
- in your htoprc file. Solution: Press I (to invert sort order).
+ 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.
+ 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 an version
+ identifying the minimum version of the configuration parser needed to
+ fully understand the configuration file format.
+ Old configuration file formats are automatically upgraded on startup.
+* 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)
+* Document historic naming of Light-Weight Processes column aka threads
+* Improve user interaction when the last process entry is selected
+* Draw the panel header on the TraceScreen (thanks to Youngjae Lee)
+* Add mouse wheel scroll and fix mouse selection on the InfoScreen
+ (thanks to Youngjae Lee)
+* Add a HugepageMeter and subtract hugepages from normal memory
+* Display wide characters in LED meters and restore non-wide ncurses support
+* Add command line option to drop Linux capabilities
+* Support scheduler affinity on platforms beyond Linux
+* Report on any failure to write the configuration file
+* Cache stderr to be able to print assert messages
+ These messages are shown in case htop terminates unexpectedly.
+* Print current settings on crash
+* Reset signal handlers on program exit
+* Add configure script option to create a static htop binary
+* Resolved longer-standing compilation issues on Solaris/Illumos
+* Check for availability of set_escdelay in configure
+ (thanks to Stefan Polluks)
+* Build system updates for autotools 2.70
