  • v0.18.2 Changes

    September 08, 2019

    🚀 Please see https://bidict.readthedocs.io/en/v0.18.2/changelog.html for the changes in this release.

  • v0.18.1 Changes

    September 03, 2019
    • 🛠 Fix a regression introduced by the memory optimizations added in 0.15.0 which caused :func:deepcopied <copy.deepcopy> and :func:unpickled <pickle.loads> bidicts to have their inverses set incorrectly. #94 <https://github.com/jab/bidict/issues/94>__

  • v0.18.0 Changes

    February 14, 2019

    • 📇 Rename bidict.BidirectionalMapping.inv to :attr:~bidict.BidirectionalMapping.inverse and make :attr:bidict.BidictBase.inv an alias for :attr:~bidict.BidictBase.inverse. #86 <https://github.com/jab/bidict/issues/86>__

    • :meth:bidict.BidirectionalMapping.__subclasshook__ now requires an inverse attribute rather than an inv attribute for a class to qualify as a virtual subclass. This breaking change is expected to affect few if any users.

    • ➕ Add Python 2/3-compatible :attr:bidict.compat.collections_abc alias.

    • ✅ Stop testing Python 3.4 on CI, and warn when Python 3 < 3.5 is detected rather than Python 3 < 3.3.

    Python 3.4 reaches end of life <https://www.python.org/dev/peps/pep-0429/>__ on 2019-03-18. As of January 2019, 3.4 represents only about 3% of bidict downloads on PyPI Stats <https://pypistats.org/packages/bidict>__.

  • v0.17.5 Changes

    November 19, 2018

    👌 Improvements to performance and delegation logic, with minor breaking changes to semi-private APIs.

    • Remove the __delegate__ instance attribute added in the previous release. It was overly general and not worth the cost.

    Instead of checking self.__delegate__ and delegating accordingly each time a possibly-delegating method is called, revert back to using "delegated-to-fwdm" mixin classes (now found in bidict._delegating_mixins), and resurrect a mutable bidict parent class that omits the mixins as :class:bidict.MutableBidict.

    • Rename __repr_delegate__ to :class:~bidict.BidictBase._repr_delegate.

  • v0.17.4 Changes

    November 14, 2018

    Minor code, interop, and (semi-)private API improvements.

    • :class:~bidict.OrderedBidict optimizations and code improvements.

    Use bidict\s for the backing _fwdm and _invm mappings, obviating the need to store key and value data in linked list nodes.

    • 🔨 Refactor proxied- (i.e. delegated-) to-_fwdm logic for better composability and interoperability.

    Drop the _Proxied* mixin classes and instead move their methods into :class:~bidict.BidictBase, which now checks for an object defined by the BidictBase.__delegate__ attribute. The BidictBase.__delegate__ object will be delegated to if the method is available on it, otherwise a default implementation (e.g. inherited from :class:~collections.abc.Mapping) will be used otherwise. Subclasses may set __delegate__ = None to opt out.

    Consolidate _MutableBidict into :class:bidict.bidict now that the dropped mixin classes make it unnecessary.

    • Change __repr_delegate__ to simply take a type like :class:dict or :class:list.

    • ⬆️ Upgrade to latest major sortedcontainers <https://github.com/grantjenks/python-sortedcontainers>__ version (from v1 to v2) for the :ref:extending:\`SortedBidict`` Recipes`.

    • bidict.compat.{view,iter}{keys,values,items} on Python 2 no longer assumes the target object implements these methods, as they're not actually part of the :class:~collections.abc.Mapping interface, and provides fallback implementations when the methods are unavailable. This allows the :ref:extending:\`SortedBidict`` Recipes` to continue to work with sortedcontainers v2 on Python 2.

  • v0.17.3 Changes

    September 18, 2018

    • 👌 Improve packaging by adding a pyproject.toml and by including more supporting files in the distribution. #81 <https://github.com/jab/bidict/pull/81>__

    • ⬇️ Drop pytest-runner and support for running tests via python setup.py test in preference to pytest or python -m pytest.

  • v0.17.2 Changes

    April 30, 2018

    Memory usage improvements +++++++++++++++++++++++++

    • 👉 Use less memory in the linked lists that back :class:~bidict.OrderedBidict\s by storing node data unpacked rather than in (key, value) tuple objects.

  • v0.17.1 Changes

    April 28, 2018

    🛠 Bugfix Release ++++++++++++++

    🛠 Fix a regression in 0.17.0 that could cause erroneous behavior ⚡️ when updating items of an :class:~bidict.Orderedbidict's inverse, e.g. some_ordered_bidict.inv[foo] = bar.

  • v0.17.0 Changes

    April 25, 2018

    Speedups and memory usage improvements ++++++++++++++++++++++++++++++++++++++

    • Pass :meth:~bidict.bidict.keys, :meth:~bidict.bidict.values, and :meth:~bidict.bidict.items calls (as well as their iter* and view* counterparts on Python 2) through to the backing _fwdm and _invm dicts so that they run as fast as possible (i.e. at C speed on CPython), rather than using the slower implementations inherited from :class:collections.abc.Mapping.

    • 👉 Use weakrefs in the linked lists that back :class:~bidict.OrderedBidict\s to avoid creating strong reference cycles.

    Memory for an ordered bidict that you create can now be reclaimed in CPython as soon as you no longer hold any references to it, rather than having to wait until the next garbage collection. #71 <https://github.com/jab/bidict/pull/71>__

    Misc ++++

    • 🔖 Add :attr:bidict.__version_info__ attribute to complement :attr:bidict.__version__.

  • v0.16.0 Changes

    April 06, 2018

    Minor code and efficiency improvements to :func:~bidict.inverted and :func:~bidict._util._iteritems_args_kw (formerly bidict.pairs()).

    Minor Breaking API Changes ++++++++++++++++++++++++++

    The following breaking changes are expected to affect few if any users.

    • Rename bidict.pairs() → :func:bidict._util._iteritems_args_kw.
