+* An empty argument would previously cause no string to be inserted. This is now changed to '' being inserted, thus prepending a space to the output of: parallel echo {} b ::: ''
+
+* $PARALLEL_ENV can now be set to an environment prepending the command. Used in env_parallel as mentioned in the manpage.
+
+* --retry-failed will retry all failed jobs in a joblog. It will ignore any command given.
+
+* --halt has been rewritten completely. You can now combine percentages with success or fail. See the man page.
+
+* Exit values 102..254 have been removed. 101 means more than 100 jobs failed.
+
+* --ssh and $PARALLEL_SSH can be used to set the command used for ssh. The command is assume to behave the same as ssh.
+
+* --fifo now works in csh, too.
