================ Change History ================ 4.0.0 (2013-08-18) ================== Finally released. 4.0.0b3 (2013-06-11) ==================== - Switch to using non-backward-compatible pickles (protocol 3, without storing bytes as strings) under Python 3. Updated the magic number for file-storage files under Python3 to indicate the incompatibility. - Fixed: A ``UnicodeDecodeError`` could happen for non-ASCII OIDs when using bushy blob layout. 4.0.0b2 (2013-05-14) ==================== - Extended the filename renormalizer used for blob doctests to support the filenames used by ZEO in non-shared mode. - Added ``url`` parameter to ``setup()`` (PyPI says it is required). 4.0.0b1 (2013-05-10) ===================== - 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. 4.0.0a4 (2012-12-17) ===================== - Enforced usage of bytes for ``_p_serial`` of persistent objects (fixes compatibility with recent persistent releases). 4.0.0a3 (2012-12-01) ===================== - Fixed: An elaborate test for trvial logic corrupted module state in a way that made other tests fail spuriously. 4.0.0a2 (2012-11-13) ===================== Bugs Fixed ---------- - An unneeded left-over setting in setup.py caused installation with pip to fail. 4.0.0a1 (2012-11-07) ===================== New Features ------------ - The ``persistent`` and ``BTrees`` packages are now released as separate distributions, on which ZODB now depends. - ZODB no longer depends on zope.event. It now uses ZODB.event, which uses zope.event if it is installed. You can override ZODB.event.notify to provide your own event handling, although zope.event is recommended. - BTrees allowed object keys with insane comparison. (Comparison inherited from object, which compares based on in-process address.) Now BTrees raise TypeError if an attempt is made to save a key with comparison inherited from object. (This doesn't apply to old-style class instances.) Bugs Fixed ---------- - Ensured that the export file and index file created by ``repozo`` share the same timestamp. https://bugs.launchpad.net/zodb/+bug/993350 - Pinned the ``transaction`` and ``manuel`` dependencies to Python 2.5- compatible versions when installing under Python 2.5. .. note:: Please see ``doc/HISTORY.txt`` for changelog entries for older versions of ZODB.
