ZODB v3.9.4 Release Notes
Release Date: 2009-12-14 // over 14 years ago-
๐ Bugs Fixed
A ZEO threading bug could cause transactions to read inconsistent data. (This sometimes caused an AssertionError in Connection._setstate_noncurrent.)
DemoStorage.loadBefore sometimes returned invalid data which would trigger AssertionErrors in ZODB.Connection.
๐ History support was broken when using stprages that work with ZODB 3.8 and 3.9.
โ zope.testing was an unnecessary non-testing dependency.
Internal ZEO errors were logged at the INFO level, rather than at the error level.
โช The FileStorage backup and restore script, repozo, gave a deprecation warning under Python 2.6.
C Header files weren't installed correctly.
The undo implementation was incorrect in ways that could cause subtle missbehaviors.
