Bump pypa/cibuildwheel from 3.4.1 to 4.1.0

[dependabot]

Bumps pypa/cibuildwheel from 3.4.1 to 4.1.0.

Release notes

Sourced from pypa/cibuildwheel's releases.

v4.1.0

• ✨ Updates Pyodide to the final 314.0.0 release, so Pyodide 3.14 wheels now build by default without the pyodide-prerelease enable flag. (#2906)
• 🐛 Raises clear errors when a build produces no wheel, instead of failing later with a confusing message (#2909)
• 🛠 Speeds up CLI startup through lazy imports on Python 3.15 (#2797)
• 📚 Adds an FAQ section on caching cibuildwheel's downloaded tools with CIBW_CACHE_PATH (#2842)
• 📚 Documentation improvements: clarifies which shell is used for command options, clarifies environment variable precedence, and fixes a dead Pyodide env info link (#2904, #2905, #2911)

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)

• 🛠 Updates Android to Python 3.13.13 and 3.14.4 (#2821)

• 🛠 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)

• 💼 Adds PEP 723 metadata for bin/ scripts and drops the bin dependency group (#2819)

• 💼 Improves Azure test reliability with retries and caching (#2890)

• 💼 Fixes Windows GitLab CI test running (#2870)

• 💼 Updates CI action pins and dev dependencies (#2902, #2867, #2851, #2843, #2826, #2823, #2820, #2807)

• 💼 Adds agent and copilot setup files (#2861)

• 💼 Uses if TYPE_CHECKING: blocks (#2866, #2864)

• 🧪 Fixes Android tests using the uv frontend (#2809)

• 🧪 Fixes the update-dependencies workflow to use uv to run nox (#2808)

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

git checkout 3.0.x
git pull

2. Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 2c3fb51b476a7cfa6c50613436c909c542b27736

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #65934: Bump pypa/cibuildwheel from 3.4.1 to 4.1.0'

4. Push to a named branch:

git push YOURFORK 3.0.x:auto-backport-of-pr-65934-on-3.0.x

5. Create a PR against branch 3.0.x, I would have named this PR:

"Backport PR #65934 on branch 3.0.x (Bump pypa/cibuildwheel from 3.4.1 to 4.1.0)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the Still Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free to suggest an improvement.
