Release notes

Sourced from immutabledict's releases.

Version 4.3.1

• Fix: fix typing issues with pytype/pyrefly. Thanks to @​mfigurnov for the PR.

Version 4.3.0

• Add typed __new__ overloads for type-safe constructor calls. Thanks to @​mfigurnov for the PR.
• Fix: correct ImmutableOrderedDict _dict_cls so that it works correctly. It actually silently used plain dict due to the issue (which actually do preserve order on Python 3.7+, so the bug was not noticed). Thanks to @​mfigurnov for the PR.
