ZODB v5.3.0 Release Notes
Release Date: 2017-08-30 // over 6 years ago-
โ Add support for Python 3.6.
โฌ๏ธ Drop support for Python 3.3.
๐ Ensure that the
HistoricalStorageAdapter
forwards therelease
method to its base instance. Seeissue 78 <https://github.com/zopefoundation/ZODB/issues/788>
_.๐ Use a higher pickle protocol (2) for serializing objects on Python 2; previously protocol 1 was used. This is much more efficient for new-style classes (all persistent objects are new-style), at the cost of being very slightly less efficient for old-style classes.
.. note:: On Python 2, this will now allow open
file
objects (but not open blobs or sockets) to be pickled (loading the object will result in a closed file); previously this would result in aTypeError
. Doing so is not recommended as they cannot be loaded in Python 3.See
issue 179 <https://github.com/zopefoundation/ZODB/pull/179>
