ZODB v5.4.0 Release Notes

Release Date: 2018-03-26 // about 6 years ago
    • ZODB now uses pickle protocol 3 for both Python 2 and Python 3.

    (Previously, protocol 2 was used for Python 2.)

    The zodbpickle package provides a zodbpickle.binary string type that should be used in Python 2 to cause binary strings to be saved in a pickle binary format, so they can be loaded correctly in Python 3. Pickle protocol 3 is needed for this to work correctly.

    • Object identifiers in persistent references are saved as zodbpickle.binary strings in Python 2, so that they are loaded correctly in Python 3.

    • If an object is missing from the index while packing a FileStorage, report its full oid.

    • Storage imports are a bit faster.

    • 👀 Storages can be important from non-seekable sources, like file-wrapped pipes.
