Release Notes: Under some Linux variants, /proc/<pid>/stat always belongs to root, thus undermining the renice efforts. and(8) now uses /proc/<pid> instead to determine the UID/GID of a process. On the and.conf.5 man page, the examples were fixed (now defaultnice instead of default).
Release Notes: The ancestors of a process can now be used as an additional criterion for renicing, and the user can specify a minimum user id and group id, below which processes are left untouched. The signal handling configuration code is more robust now, and some rare 64bit bugs have been fixed.
Release Notes: This release adds a Zombie fix for Linux.
Release Notes: Ported to FreeBSD.
Release Notes: This release adds a port to IRIX/IRIX64 and SunOS, a fix to stop overwriting existing configurations through make install, a small docs improvement (command name and regexes), and a change to a misleading log message (a seemingly negative nice level). gtop has been added to the default config file.
