I have merged the 'py3' branch to 'master': - - All tests pass under all four platforms using buildout. - - All unit tests pass on all four platforms using 'setup.py test'. I added the following note to the changelog: ZODB 4.0.x is supported on Python 3.x for *new* applications only. Due to changes in the standard library's pickle support, the Python3 support does **not** provide forward- or backward-compatibility at the data level with Python2. A future version of ZODB may add such support. Applications which need migrate data from Python2 to Python3 should plan to script this migration using separte databases, e.g. via a "dump-and-reload" approach, or by providing explicit fix-ups of the pickled values as transactions are copied between storages. I pushed out a ZODB 4.0.0b1 release after the merge. If the buildbots stay green over the weekend, I think we can release a 4.0.0 final early next week.
