* The quoting engine has been changed. Instead of using \-quoting GNU
Parallel now uses '-quoting in bash/ash/dash/ksh. This should
improve compatibility with different locales. This is a big change
causing this release to be alpha quality.
* The CPU calculation has changed. By default GNU Parallel uses the
number of CPU threads as the number of CPUs. This can be changed to
the number of CPU cores or number of CPU sockets with
--use-cores-instead-of-threads or --use-sockets-instead-of-threads.
* The detected number of sockets, cores, and threads can be shown with
--number-of-sockets, --number-of-cores, and --number-of-threads.
* env_parallel now support mksh using env_parallel.mksh.
* GNU Parallel is distributed as part of Snippy
