[dependabot]

Bumps pypa/cibuildwheel from 3.4.1 to 4.0.0.

Release notes

Sourced from pypa/cibuildwheel's releases.

v4.0.0

See @​henryiii's release post for more info on new features!

• 🌟 Adds wheel auditing with abi3audit as a default after the repair step, with new audit-requires and audit-command options (#2805)

• 🌟 Adds pyemscripten platform tag support (PEP 783), updates Pyodide to 314.0.0a2, and adds a pyodide-eol enable flag for building end-of-life Pyodide versions (#2812, #2848)

• 🌟 Sets up delvewheel as the default repair-wheel-command for Windows, so extension module DLLs are now bundled automatically. Skip by setting it to empty if not needed. (#2831)

• ✨ Adds CPython 3.15 support, under the enable option cpython-prerelease. This version of cibuildwheel uses 3.15.0b2. (#2833, #2850)

  While CPython is in beta, the ABI can change, so your wheels might not be compatible with the final release. For this reason, we don't recommend distributing wheels until RC1, at which point 3.15 will be available in cibuildwheel without the flag.

• ✨ Adds CPython 3.15 support for iOS and Android (#2857, #2858)

• ✨ Adds Android improvements for building NumPy and related packages, including auditwheel support, pkg-config and Fortran configuration, and the xbuild-files option (#2695)

• ✨ Adds CIBUILDWHEEL_BUILD_IDENTIFIER environment variable set to the current build identifier (e.g. cp311-manylinux_x86_64) during per-build steps (#2872)

• ✨ Adds {project} and {package} placeholders to config-settings (#2827)

• ⚠️ Drops support for Python 3.8 (#2686)

• ⚠️ Removes the experimental CPython 3.13 free-threading builds and the cpython-freethreading enable option. CPython 3.14+ free-threading support remains available without the enable flag. (#2684)

• ⚠️ Drops support for Cirrus CI, which is shutting down June 1, 2026 (#2817)

• ⚠️ Drops GraalPy 3.11 (gp311) support, as agreed in #2741, and removes GraalPy 24-only workarounds (#2895)

• 🔐 Adds SHA256 verification for direct downloads of Python interpreters, virtualenv, and python-build-standalone assets (#2873)

• 🔐 Adds tarfile extraction filter for safe archive extraction (#2856)

• 🐛 Fixes UV_PYTHON not being set for before-build on Linux when using uv as the build-frontend (#2830)

• 🐛 Fixes detection of musl libc when downloading python-build-standalone, which previously always selected the gnu asset on musl hosts like Alpine (#2889)

• 🐛 Fixes config-settings expansion when {project} or {package} contains spaces or backslashes (#2886)

• 🐛 Prevents deadlock when linux32 fails and forwards platform args to the sanity check (#2880, #2888)

• 🐛 Fixes container resource leaks on start failure and during teardown (#2879, #2887)

• 🐛 Removes potential partial cache-population in case of error (#2892)

• 🐛 Raises a clear error when ANDROID_API_LEVEL is not an integer (#2891)

• 🐛 Replaces assert with proper exception in python-build-standalone (#2859)

• 🐛 Uses ConfigurationError when package_dir is outside cwd instead of a generic Exception (#2898)

• 🛠 Updates dependencies and container pins (#2893, #2882, #2874, #2868, #2862, #2884, #2845, #2837, #2818, #2810, #2838, #2813)

• 🛠 Applies Pyodide-specific patches to the Emscripten toolchain installation (#2800)

• 🛠 Uses python -V -V for Windows build diagnostics (#2832)

• 🛠 Simplifies pinned container image lookup (#2897)

• 🛠 Minor fixups across error messages, OCI container, and options (#2860)

Restore Python 3.8 wheel builds

In build_wheels_qemu_cp, the matrix still includes build_cp: cp38, so this upgraded action will run with CIBW_BUILD=cp38-${{ matrix.build_sub }}*. I checked cibuildwheel v4.0.0's release notes and options docs: v4.0.0 drops Python 3.8, supported identifiers now start at cp39, and no selected builds returns error code 3 unless allow-empty is set. That means both cp38 riscv64 jobs fail, and because upload_all needs build_wheels_qemu_cp, release publishing is blocked whenever this workflow runs; keep 3.4.1 for cp38 or remove/update the cp38 matrix/support metadata.
