- update to 12.4.0:
* All commands: Display statistics in color by default when the
output is connected to a terminal.
* sar: Now pretty-print all device names by default (that is to
say, you no longer need to use option -p with option -d for that).
* cifsiostat, iostat, sar: Add new --pretty option (this option
makes the reports easier to read when long item names are used).
* iostat: No longer use sysstat.ioconf file to determine the name
of the devices. This file gave a wrong name for some devices
with big minor numbers.
* iostat, sar: Make device name consistent between both of them.
* configure: Add new option "--enable-use-crond" to use standard
cron daemon even if systemd is installed.
* configure: Use AC_COMPILE_IFELSE instead of old AC_TRY_COMPILE
macro. Remove other obsolete autoconf macros.
* configure: Add new option "delay_range=". Used by sa2 script
to wait for a random delay.
* configure: Fix --enable-debuginfo option.
* sa1: Insert a comment in daily datafile on system suspend/resume.
* sa2: Wait for a random delay before running to prevent massive
I/O burst on some systems.
* sar: Fix typo in manual page.
* sar, iostat, cifsiostat, mpstat, pidstat, tapestat and sa1 manual
pages updated.
* Update style for all manual pages.
* Compress manual pages by default when they are installed.
* Makefile: Remove all reports and date files (even those compressed
with another program than gzip) when told to do so.
* Add pcp help file to be used with iconfig script.
* Update Travis script (now calls do_test script).
