Related issues and pull requests on GitHub:
:issue:292.
Stopped reallocating memory for the internal htkeys_t structure when inserting new items if the

v6.5.0
Compare Source
=====
(2025-06-17)
.. note::
The release was yanked because of :issue:1195, multidict 6.5.1 should be used
instead.
Features
Replace internal implementation from an array of items to hash table.
algorithmic complexity for lookups is switched from O(N) to O(1).
The hash table is very similar to :class:dict from CPython but it allows keys duplication.
The benchmark shows 25-50% boost for single lookups, x2-x3 for bulk updates, and x20 for
some multidict view operations. The gain is not for free:
:class:~multidict.MultiDict.add and :class:~multidict.MultiDict.extend are 25-50%
slower now. We consider it as acceptable because the lookup is much more common
operation that addition for the library domain.

:issue:1128.
Contributor-facing changes
Builds have been added for arm64 Windows
wheels and the reusable-build-wheel.yml
template has been modified to allow for
an os value (windows-11-arm) which
does not end with the -latest postfix.

(2025-05-19)
Bug fixes
Fixed a segmentation fault when calling :py:meth:multidict.MultiDict.setdefault with a single argument -- by :user:bdraco.
Related issues and pull requests on GitHub:
:issue:1160.
Fixed a segmentation fault when attempting to directly instantiate view objects
(multidict._ItemsView, multidict._KeysView, multidict._ValuesView) -- by :user:bdraco.
View objects now raise a proper :exc:TypeError with the message "cannot create '...' instances directly"
when direct instantiation is attempted.
View objects should only be created through the proper methods: :py:meth:multidict.MultiDict.items,
:py:meth:multidict.MultiDict.keys, and :py:meth:multidict.MultiDict.values.
Related issues and pull requests on GitHub:
:issue:1164.

(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.

:issue:1097.

: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() , :py:meth:MultiDict.getall() , :py:meth:MultiDict.get() , :py:meth:MultiDict.pop() , :py:meth:MultiDict.popone() , and :py:meth: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.

: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.

: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%.
