6.6.0

(2025-06-27)

Features

    Related issues and pull requests on GitHub: #1192.

  • The reusable-cibuildwheel.yml workflow has been refactored to be more generic and ci-cd.yml now holds all the configuration toggles – by @webknjaz.

    Related issues and pull requests on GitHub: #1193.

6.5.0

(2025-06-17)

Note

The release was yanked because of #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 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: add and 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.

    Related issues and pull requests on GitHub: #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.

    Related issues and pull requests on GitHub: #1167.

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: #965.

  • Rewrote multidict.CIMultiDict and it proxy to always return multidict.istr keys. istr is derived from 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: #1097.

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

    Related issues and pull requests on GitHub: #1100.

Features

  • Implemented a custom parser for METH_FASTCALL | METH_KEYWORDS protocol – by @asvetlov.

    The patch re-enables fast call protocol in the multidict C Extension.

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

    Related issues and pull requests on GitHub: #1070.

  • The C-extension no longer pre-allocates a Python exception object in lookup-related methods of MultiDict when the passed-in key is not found but default value is provided.

    Namely, this affects MultiDict.getone(), MultiDict.getall(), MultiDict.get(), MultiDict.pop(), MultiDict.popone(), and MultiDict.popall().

    Additionally, the MultiDict comparison with regular dictionaries is now about 60% faster on Python 3.13+ in the fallback-to-default case.

    Related issues and pull requests on GitHub: #1078.

  • Implemented __repr__() for C Extension classes in C.

    The speedup is about 2.5 times.

    Related issues and pull requests on GitHub: #1081.

  • Made C version of multidict.istr pickleable.

    Related issues and pull requests on GitHub: #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: #1101.

  • multidict.MultiDict.popitem() is changed to remove the latest entry instead of the first.

    It gives O(1) amortized complexity.

    The standard dict.popitem() removes the last entry also.

    Related issues and pull requests on GitHub: #1105.

Contributor-facing changes

  • Started running benchmarks for the pure Python implementation in addition to the C implementation – by @bdraco.

    Related issues and pull requests on GitHub: #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%.

    Now, there is a set of the pytest fixtures that is set up in a parametrized manner allowing to have a consistent way of accessing mirrored multidict implementations across all the tests.

    This change also implemented a pair of CLI flags (--c-extensions / --no-c-extensions) that allow to explicitly request deselecting the tests running against the C-extension.

    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. (#682)

6.0.0 (2022-01-22)

Features
