6.3.1
=====

*(2025-04-01)*

  *Related issues and pull requests on GitHub:*
  :issue:`1113`.

----

6.3.0
=====

*(2025-03-31)*

Bug fixes
---------

- Set operations for ``KeysView`` and ``ItemsView`` of case-insensitive \ 
multidicts and their proxies are processed in case-insensitive manner.

  *Related issues and pull requests on GitHub:*
  :issue:`965`.

- Rewrote :class:`multidict.CIMultiDict` and it proxy to always return
  :class:`multidict.istr` keys. ``istr`` is derived from :class:`str`,
  thus the change is backward compatible.

  The performance boost is about 15% for some operations for C Extension,
  pure Python implementation have got a visible (15% - 230%) speedup as well.

  *Related issues and pull requests on GitHub:*
  :issue:`1097`.

- Fixed a crash when extending a multidict from multidict proxy if C Extensions \ 
were used.

  *Related issues and pull requests on GitHub:*
  :issue:`1100`.

Features
--------

- Implemented a custom parser for ``METH_FASTCALL | METH_KEYWORDS`` protocol
  -- by :user:`asvetlov`.

  The patch re-enables fast call protocol in the :py:mod:`multidict` C Extension.

  Speedup is about 25%-30% for the library benchmarks for Python 3.12+.

  *Related issues and pull requests on GitHub:*
  :issue:`1070`.

- The C-extension no longer pre-allocates a Python exception object in
  lookup-related methods of :py:class:`~multidict.MultiDict` when the
  passed-in *key* is not found but *default* value is provided.

  Namely, this affects :py:meth:`MultiDict.getone()
  <multidict.MultiDict.getone>`, :py:meth:`MultiDict.getall()
  <multidict.MultiDict.getall>`, :py:meth:`MultiDict.get()
  <multidict.MultiDict.get>`, :py:meth:`MultiDict.pop()
  <multidict.MultiDict.pop>`, :py:meth:`MultiDict.popone()
  <multidict.MultiDict.popone>`, and :py:meth:`MultiDict.popall()
  <multidict.MultiDict.popall>`.

  Additionally, the :py:class:`~multidict.MultiDict` comparison with
  regular :py:class:`dict`\ ionaries is now about 60% faster
  on Python 3.13+ in the fallback-to-default case.

  *Related issues and pull requests on GitHub:*
  :issue:`1078`.

- Implemented ``__repr__()`` for C Extension classes in C.

  The speedup is about 2.5 times.

  *Related issues and pull requests on GitHub:*
  :issue:`1081`.

- Made C version of :class:`multidict.istr` pickleable.

  *Related issues and pull requests on GitHub:*
  :issue:`1098`.

- Optimized multidict creation and extending / updating if C Extensions are used.

  The speedup is between 25% and 70% depending on the usage scenario.

  *Related issues and pull requests on GitHub:*
  :issue:`1101`.

- :meth:`multidict.MultiDict.popitem` is changed to remove
  the latest entry instead of the first.

  It gives O(1) amortized complexity.

  The standard :meth:`dict.popitem` removes the last entry also.

  *Related issues and pull requests on GitHub:*
  :issue:`1105`.

Contributor-facing changes
--------------------------

- Started running benchmarks for the pure Python implementation in addition to \ 
the C implementation -- by :user:`bdraco`.

  *Related issues and pull requests on GitHub:*
  :issue:`1092`.

- The the project-wide Codecov_ metric is no longer reported
  via GitHub Checks API. The combined value is not very useful
  because one of the sources (MyPy) cannot reach 100% with the
  current state of the ecosystem. We may want to reconsider in
  the future. Instead, we now have two separate
  “runtime coverage” metrics for library code and tests.
  They are to be kept at 100% at all times.
  And the “type coverage” metric will remain advisory, at a
  lower threshold.

  The default patch metric check is renamed to “runtime”
  to better reflect its semantics. This one will also require
  100% coverage.
  Another “typing” patch coverage metric is now reported
  alongside it. It's considered advisory, just like its
  project counterpart.

  When looking at Codecov_, one will likely want to look at
  MyPy and pytest flags separately. It is usually best to
  avoid looking at the PR pages that sometimes display
  combined coverage incorrectly.

  The change additionally disables the deprecated GitHub
  Annotations integration in Codecov_.

  Finally, the badge coloring range now starts at 100%.

py-multidict: updated to 6.1.0

6.1.0 (2024-09-09)

Bug fixes

- Covered the unreachable code path in
  ``multidict._multidict_base._abc_itemsview_register()``
  with typing

Features

- Added support for Python 3.13 -- by :user:`bdraco`.

Removals and backward incompatible breaking changes

- Removed Python 3.7 support

Log message:
py-multidict: updated to 6.0.5

6.0.5 (2024-02-01)
==================

Bug fixes
---------

- Upgraded the C-API macros that have been deprecated in Python 3.9
  and later removed in 3.13 -- by :user:`iemelyanov`.

- Reverted to using the public argument parsing API
  :c:func:`PyArg_ParseTupleAndKeywords` under Python 3.12
  -- by :user:`charles-dyfis-net` and :user:`webknjaz`.

  The effect is that this change prevents build failures with
  clang 16.9.6 and gcc-14 reported in :issue:`926`. It also
  fixes a segmentation fault crash caused by passing keyword
  arguments to :py:meth:`MultiDict.getall()
  <multidict.MultiDict.getall>` discovered by :user:`jonaslb`
  and :user:`hroncok` while examining the problem.

- Fixed a ``SystemError: null argument to internal routine`` error on
  a ``MultiDict.items().isdisjoint()`` call when using C Extensions.

Log message:

6.0.4

Bugfixes

- Fixed a type annotations regression introduced in v6.0.2 under Python versions \ 
<3.10. It was caused by importing certain types only available in newer \ 
versions.

Log message:
py-multidict: updated to 6.0.3

6.0.3 (2022-12-03)
==================

Features
--------

- Declared the official support for Python 3.11

Log message:
py310-multidict: update to 6.0.2.

6.0.2 (2022-01-24)
==================

Bugfixes
--------

- Revert :issue:`644`, restore type annotations to as-of 5.2.0 version. \ 
(:issue:`688`)

6.0.1 (2022-01-23)
==================

Bugfixes
--------

- Restored back ``MultiDict``, ``CIMultiDict``, ``MultiDictProxy``, and
  ``CIMutiDictProxy`` generic type arguments; they are parameterized by value \ 
type, but the
  key type is fixed by container class.

  ``MultiDict[int]`` means ``MutableMultiMapping[str, int]``. The key type of
  ``MultiDict`` is always ``str``, while all str-like keys are accepted by API and
  converted to ``str`` internally.

  The same is true for ``CIMultiDict[int]`` which means ``MutableMultiMapping[istr,
  int]``. str-like keys are accepted but converted to ``istr`` internally. \ 
(:issue:`682`)

Log message:
py-multidict: update to 6.0.0.

Features
--------

- Use ``METH_FASTCALL`` where it makes sense.

  ``MultiDict.add()`` is 2.2 times faster now, ``CIMultiDict.add()`` is 1.5 \ 
times faster.
  The same boost is applied to ``get*()``, ``setdefault()``, and ``pop*()`` \ 
methods. (:issue:`681`)

Bugfixes
--------

- Fixed type annotations for keys of multidict mapping classes. (:issue:`644`)
- Support Multidict[int] for pure-python version.
  ``__class_getitem__`` is already provided by C Extension, making it work with \ 
the pure-extension too. (:issue:`678`)

Deprecations and Removals
-------------------------

- Dropped Python 3.6 support (:issue:`680`)
