ZODB v4.0.0.b1 Release Notes

Release Date: 2013-05-10 // almost 11 years ago

    • 🏗 Skipped non-unit tests in setup.py test. Use the buildout to run tests requiring "layer" support.

    • 👻 Included the filename in the exception message to support debugging in case loadBlob does not find the file.

    • ➕ Added support for Python 3.2 / 3.3.

    .. note::

    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.
