I'd like to work through the platform support related open PRs and issues, get them merged/addressed, and then tag a new release.

Platforms to be added compared to the current 1.4.2 release for which there are wheels on PyPI:

• Linux aarch64 (new)
• macOS x86-64 (this got lost but used to be there)
• free-threaded CPython (new)

In addition, it looks like it's time to drop Python 3.9, either before or after this release. NumPy has dropped 3.9 a long time ago, and has even already droppped 3.10 in main. SPEC 0 says that we're already halfway through the 3.11 support window right now. Dropping 3.9 will also be helpful to stop the wheel build matrix from growing a lot. Around September/October we'll need to support Python 3.14, and we may want to consider doing 3.11-3.14 at that point.

@rdbisme does that sound good to you? And would you prefer for that release to be 1.5.0 or 1.4.3? And drop 3.9 now, or after the next release?
