 New in this release:
 
-* Encoding of remote commands has changed. This limits the length of remote commands to less than half. It also requires $REMOTE_TMPDIR to be writable.
-
-* Time functions hh_mm_ss() hhmmss() hh_mm() hhmm() are now available for {= =}.
-
-* parallel_options_map.pdf is a map showing which options other options relate to.
-
-* {uniq} added to --plus to only run jobs with unique values.
+<<>>
 
 * Bug fixes and man page updates: Many options now have a 'See also' section.

-GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.
