``BTrees`` Changelog
====================
4.3.1 (2016-05-16)
------------------
- Packaging: fix password used to automate wheel creation on Travis.
4.3.0 (2016-05-10)
------------------
- Fix unexpected ``OverflowError`` when passing 64bit values to long
keys / values on Win64. See:
https://github.com/zopefoundation/BTrees/issues/32
- When testing ``PURE_PYTHON`` environments under ``tox``, avoid poisoning
the user's global wheel cache.
- Ensure that he pure-Python implementation, used on PyPy and when a C
compiler isn't available for CPython, pickles identically to the C
version. Unpickling will choose the best available implementation.
This change prevents interoperability problems and database corruption if
both implementations are in use. While it is no longer possible to
pickle a Python implementation and have it unpickle to the Python
implementation if the C implementation is available, existing Python
pickles will still unpickle to the Python implementation (until
pickled again). See:
https://github.com/zopefoundation/BTrees/issues/19
- Avoid creating invalid objects when unpickling empty BTrees in a pure-Python
environment.
- Drop support for Python 2.6 and 3.2.
4.2.0 (2015-11-13)
------------------
- Add support for Python 3.5.
4.1.4 (2015-06-02)
------------------
- Ensure that pure-Python Bucket and Set objects have a human readable
``__repr__`` like the C versions.
4.1.3 (2015-05-19)
------------------
- Fix ``_p_changed`` when removing items from small pure-Python
BTrees/TreeSets and when adding items to small pure-Python Sets. See:
https://github.com/zopefoundation/BTrees/issues/13
4.1.2 (2015-04-07)
------------------
- Suppress testing 64-bit values in OLBTrees on 32 bit machines.
See: https://github.com/zopefoundation/BTrees/issues/9
- Fix ``_p_changed`` when adding items to small pure-Python
BTrees/TreeSets. See:
https://github.com/zopefoundation/BTrees/issues/11
4.1.1 (2014-12-27)
------------------
- Accomodate long values in pure-Python OLBTrees.
4.1.0 (2014-12-26)
------------------
- Add support for PyPy and PyPy3.
- Add support for Python 3.4.
- BTree subclasses can define ``max_leaf_size`` or ``max_internal_size``
to control maximum sizes for Bucket/Set and BTree/TreeSet nodes.
- Detect integer overflow on 32-bit machines correctly under Python 3.
- Update pure-Python and C trees / sets to accept explicit None to indicate
max / min value for ``minKey``, ``maxKey``. (PR #3)
- Update pure-Python trees / sets to accept explicit None to indicate
open ranges for ``keys``, ``values``, ``items``. (PR #3)
4.0.8 (2013-05-25)
------------------
- Fix value-based comparison for objects under Py3k: addresses invalid
merges of ``[OLI]OBTrees/OBuckets``.
- Ensure that pure-Python implementation of ``OOBTree.byValue`` matches
semantics (reversed-sort) of C implementation.
4.0.7 (2013-05-22)
------------------
- Issue #2: compilation error on 32-bit mode of OS/X.
- Test ``PURE_PYTHON`` environment variable support: if set, the C
extensions will not be built, imported, or tested.
4.0.6 (2013-05-14)
------------------
- Changed the ``ZODB`` extra to require only the real ``ZODB`` package,
rather than the ``ZODB3`` metapackage: depending on the version used,
the metapackage could pull in stale versions of **this** package and
``persistent``.
- Fixed Python version check in ``setup.py``.
4.0.5 (2013-01-15)
------------------
- Fit the ``repr`` of bucket objects, which could contain garbage
characters.
4.0.4 (2013-01-12)
------------------
- Emulate the (private) iterators used by the C extension modules from
pure Python. This change is "cosmetic" only: it prevents the ZCML
``zope.app.security:permission.zcml`` from failing. The emulated
classes are **not** functional, and should be considered implementation
details.
- Accomodate buildout to the fact that we no longer bundle a copy
of 'persistent.h'.
- Fix test failures on Windows: no longer rely on overflows from
``sys.maxint``.
4.0.3 (2013-01-04)
------------------
- Added ``setup_requires==['persistent']``.
4.0.2 (2013-01-03)
------------------
- Updated Trove classifiers.
- Added explicit support for Python 3.2, Python 3.3, and PyPy.
Note that the C extensions are not (yet) available on PyPy.
- Python reference implementations now tested separately from the C
verions on all platforms.
- 100% unit test coverage.
4.0.1 (2012-10-21)
------------------
- Provide local fallback for persistent C header inclusion if the
persistent distribution isn't installed. This makes the winbot happy.
4.0.0 (2012-10-20)
------------------
Platform Changes
################
- Dropped support for Python < 2.6.
- Factored ``BTrees`` as a separate distribution.
Testing Changes
###############
- All covered platforms tested under ``tox``.
- Added support for continuous integration using ``tox`` and ``jenkins``.
- Added ``setup.py dev`` alias (installs ``nose`` and ``coverage``).
- Dropped dependency on ``zope.testing`` / ``zope.testrunner``: tests now
run with ``setup.py test``.
Documentation Changes
#####################
- Added API reference, generated via Spinx' autodoc.
- Added Sphinx documentation based on ZODB Guide (snippets are exercised
via 'tox').
- Added ``setup.py docs`` alias (installs ``Sphinx`` and
``repoze.sphinx.autointerface``).
