The "-L" flag was added to follow symbolic links. Compatibility with Mail::Mbox::MessageParser version 1.5000 and later is now ensured. testspeed.pl was fixed for newer versions of Benchmark::Timer. Tzip support was dropped. Some documentation was improved.
Test cases have been improved to be more robust. -F now works again. This release ccorrectly handles DOS-style line endings in mailboxes. Single dates have been changed so that they are treated as inferred spans instead of a single day.
