This release adds a "errors" argument, which behaves as with the Python "open()" call, to handle UnicodeDeocdeErrors on the input.
The 0.9.0 release has been running in my production environment for the last 2 months, handling many gigabytes of mail log data, FYI.
This release is identical to 0.9.1, I forgot to update the version number in the setup.cfg
