Update to 4.10.0. From the changelog:

- add "message_log_verbose" option, defaulting to false. If true,

  more information than the default of just messages retrieved.
  Thanks: Matthias Andree, Gregory Morozov.

  re-retrieved), but operation will continue, with the corrupt lines
  logged. Thanks: Domen Puncer.

- Improve information sent to logfile about messages not retrieved.
  Thanks: Scott.

Log message:
Update to 4.8.2. From the changelog:

- for IMAP retrievers, keep message state around for 30 days even
  if the corresponding message isn't seen. This allows users to
  have multiple rc files with different IMAP folders to retrieve
  from without losing their "seen" mail state for the folders they're
  not currently retrieving from. You no longer need to work around
  this with different getmail state directories. Thanks: ?.

Log message:
Update PYTHON_VERSIONS_COMPATIBLE
- assume that Python 2.4 and 2.5 are compatible and allow checking for
fallout.
- remove PYTHON_VERSIONS_COMPATIBLE that are obsoleted by the 2.3+
default. Modify the others to deal with the removals.
