What's new in version 0.8.3 * BUGFIX: Fix crash on F6 key (thanks to Rainer Suhm) * BUGFIX: Fix a minor bug which affected the build process. What's new in version 0.8.2 * Integrated lsof (press 'l') * Fix display of gigabyte-sized values (thanks to Andika Triwidada) * Option to display hostname in the meters area * Rename VEID to CTID in OpenVZ systems (thanks to Thorsten Schifferdecker) * Corrections to the desktop entry file (thanks by Samuli Suominen) * BUGFIX: Correct page size calculation for FreeBSD systems (thanks to Andrew Paulsen) * Allow compilation without PLPA on systems that don't support it (thanks to Timothy Redaelli) * BUGFIX: Fix missing tree view when userland threads are hidden (thanks to Josh Stone) * BUGFIX: Fix for VPID on OpenVZ systems (thanks to Wolfgang Frisch) What's new in version 0.8.1 * Linux-VServer support (thanks to Jonathan Sambrook and Benedikt Bohm) * Battery meter (thanks to Ian Page Hands) * BUGFIX: Fix collection of IO stats in multithreaded processes (thanks to Gerhard Heift) * Remove assertion that fails on hardened kernels (thanks to Wolfram Schlich for the report) What's new in version 0.8 * Ability to change sort column with the mouse by clicking column titles (click again to invert order) * Add support for Linux per-process IO statistics, enabled with the --enable-taskstats flag, which requires a kernel compiled with taskstats support. (thanks to Tobias Oetiker) * Add Unicode support, enabled with the --enable-unicode flag, which requires libncursesw. (thanks to Sergej Pupykin) * BUGFIX: Fix display of CPU count for threaded processes. When user threads are hidden, process now shows the sum of processor usage for all processors. When user threads are displayed, each thread shows its own processor usage, including the root thread. (thanks to Bert Wesarg for the report) * BUGFIX: avoid crashing when using many meters (thanks to David Cho for the report) What's new in version 0.7 * CPU affinity configuration ('a' key) * Improve display of tree view, properly nesting threads of the same app based on TGID. * IO-wait time now counts as idle time, which is a more accurate description. It is still available in split time, now called detailed CPU time. (thanks to Samuel Thibault for the report) * BUGFIX: Correct display of TPGID field * Add TGID field * BUGFIX: Don't crash with invalid command-line flags (thanks to Nico Golde for the report) * Fix GCC 4.3 compilation issues (thanks to Martin Michlmayr for the report) * OpenVZ support, enabled at compile-time with the --enable-openvz flag.

(thanks to Wolfram Schlich for assistance with debugging) * Separate proc and memory debugging into separate #defines. * BUGFIX: Fix message when configure fails due to missing libraries (thanks to Jon) * BUGFIX: Don't truncate value when displaying a very large process (thanks to Bo Liu) What's new in version 0.6.4 * Add an option to split the display of kernel time in the CPU meter into system, IO-wait, IRQ and soft-IRQ. (thanks to Philipp Richter) * --sort-key flag in the command-line, overriding the saved setting in .htoprc for the session. (thanks to Rodolfo Borges) * BUGFIX: Fixed string overflow on uptime display. (thanks to Marc Cahalan) What's new in version 0.6.3 * Performance improvements: uses much less CPU than the previous release with the default setup. * Use 64-bit values when storing processor times to avoid overflow. * Memory consumption improvements, compensating storage of 64-bit values. * Internal change: rename TypedVector to Vector and ListBox (and related classes) to Panel. * Have configure actually fail when needed libraries or headers are not found. * Horizontally scroll in larger increments when on the Linux console because of slow update of unaccelerated fb * No longer untag processes after sending a signal (useful for when SIGTERM fails and one wants to try again with SIGKILL). All processes can be untagged at once with 'U'. (thanks to A. Costa for the suggestion) What's new in version 0.6.2 * BUGFIX: Fixed crash when using some .htoprc files from 0.6 (thanks to Wolfram Schlich and John Thomas for the reports) * BUGFIX: Ensure changes to color scheme are saved * BUGFIX: Make configure behave correctly with --with-proc * Minor addition to .desktop file. What's new in version 0.6.1 * New meter type: "All CPUs", which dynamically adjusts to the number of CPUs present in the machine. Note that because of this, older versions of htop may crash when using an .htoprc file modified my the newer version. * Accept --with-proc=
