* Drop Python 3.9 support, require Python 3.10+
Python 3.9 reached end-of-life and the codebase uses PEP 604 union
type syntax (str | None) which requires Python 3.10+.
Changes:
- Remove Python 3.9 from CI build matrix
- Update requires-python to >=3.10 in all pyproject.toml files
- Update classifiers to reflect supported Python versions (3.10-3.13)
* Remove macos-13 from CI build matrix
GitHub Actions deprecated macos-13 runner (brownout started Sept 2025,
fully retired Dec 2025). See: https://github.blog/changelog/2025-09-19-github-actions-macos-13-runner-image-is-closing-down/
* Add macos-15-large for Intel Mac builds
Replace deprecated macos-13 with macos-15-large (x86_64 Intel)
to continue supporting Intel Mac users.
* Set MACOSX_DEPLOYMENT_TARGET=13.x for Intel builds
Intel Mac wheels (macos-15-large) now target macOS 13.0/13.3 for
backward compatibility, allowing macOS 13/14/15 Intel users to
install pre-built wheels.
* Remove Intel Mac builds (macos-15-large requires paid plan)
Intel Mac users can build from source. This avoids:
- Paid GitHub Actions runners (macos-15-large)
- Complex cross-compilation setup
* Add macos-15-intel for Intel Mac builds (free runner)
Use macos-15-intel (free standard runner) instead of macos-15-large
(paid). This provides Intel Mac wheel support until Aug 2027.
- MACOSX_DEPLOYMENT_TARGET=13.0 for backward compatibility
- Replaces deprecated macos-13 runner
* Add macOS 26 (beta) to build matrix
Add macos-26 (arm64) runner to the build matrix for testing future
macOS compatibility. This is currently a beta runner that helps ensure
wheels work on upcoming macOS versions.
* Fix macos-15-intel deployment target
The macos-15-intel runner runs macOS 15.7, so Homebrew libraries are
built for macOS 14+. Setting MACOSX_DEPLOYMENT_TARGET=13.0 causes
delocate to fail because system libraries require newer macOS.
Fix by setting deployment target to 15.0 for macos-15-intel, matching
the actual OS version. Intel Mac users will need macOS 15+.
* Exclude macos-15-intel + Python 3.13 (no PyTorch wheels available)
