* --memsuspend suspends jobs when there is little memory free. This
  way you can run jobs in parallel that added up potentially will take
  up more RAM than is available.

* $PARALLEL_ARGHOSTGROUPS and the replacement string {agrp} will give
  the hostgroup given on the argument when using --hostgroup.

* Handy time functions for {= =}: yyyy_mm_dd_hh_mm_ss()
  yyyy_mm_dd_hh_mm() yyyy_mm_dd() yyyymmddhhmmss() yyyymmddhhmm()
  yyyymmdd() hash($str)

* Bug fixes and man page updates.

* --pipe engine changed making --pipe alpha quality.

* --results -.json outputs results as JSON objects on stdout (standard
  output).

* --delay 123auto will auto-adjust --delay. If jobs fail due to being
  spawned too quickly, --delay will exponentially increase.

* --plus sets {hgrp} that gives the intersection of the hostgroups of
  the job and the sshlogin that the job is run on.
