I've finally released ZODB 3.8.1 (final):
This release has *many* bug fixes and is highly recommended.
(There isn't a Windows release for Python 2.6 and I believe there are
currently issues with running ZODB 3.8.1 with Python 2.6 on Windows.
There aren't any known issues, other than deprecation warnings, with
running ZODB 3.8.1 under Python 2.6 on Unix-based platforms.)
