Release notes

Sourced from multidict's releases.

6.6.2

Bug fixes

• Fixed a memory corruption issue in the C implementation of _md_shrink() that could lead to segmentation faults and data loss when items were deleted from a :class:~multidict.MultiDict. The issue was an edge case in the pointer arithmetic during the compaction phase -- by :user:bdraco.

  Related issues and pull requests on GitHub: #1221, #1222.

• Fixed format string compilation errors in debug builds on 32-bit platforms by using portable %zd format specifiers for Py_ssize_t values instead of %ld -- by :user:bdraco.

  Related issues and pull requests on GitHub: #1225, #1226.

Packaging updates and notes for downstreams

• Re-enabled 32-bit Linux wheel builds that were disabled by default in cibuildwheel 3.0.0 -- by :user:bdraco.

  Related issues and pull requests on GitHub: #1225, #1227.

6.6.1

Bug fixes

• If :meth:multidict.MultiDict.extend, :meth:multidict.MultiDict.merge, or :meth:multidict.MultiDict.update raises an exception, now the multidict internal state is correctly restored. Patch by :user:asvetlov.

  Related issues and pull requests on GitHub: #1215.
