Release Notes: Support for mbox folders compressed with the bzip2 algorithm has been implemented. Compilation issues on recent Red Hat systems and a bug that caused problems with deleting files from mbox folders have been fixed.
Release Notes: Crashes which occured upon reading of MH folders have been fixed, as well as a potential problem with mbox and maildir folders with the same cause. MH and maildir backends no longer read files which are not RFC 2822 messages. The ability to read gzip compressed mbox folders from standard input has been added, too.
Release Notes: Mboxgrep can now read mbox folders or output of another Mboxgrep process from standard input.
Release Notes: A compilation bug has been fixed.

Release Notes: A new ability to filter out duplicate messages.
Release Notes: Fixes for a FreeBSD compile bug and a bug which caused it to coredump on messages with an empty body, and an ability to select the file locking mechanism at run time.
