Bump pypa/cibuildwheel from 3.3.1 to 3.4.1

[dependabot]

Bumps pypa/cibuildwheel from 3.3.1 to 3.4.1.

Release notes

Sourced from pypa/cibuildwheel's releases.

v3.4.1

• ⚠️ Building for the experimental CPython 3.13 free-threading variant is now deprecated. That functionality will be removed in the next minor release. The enable option cpython-freethreading is therefore also deprecated. Builds specifying enable = "all" no longer select cpython-freethreading. CPython 3.14 free-threading support remains available without the enable flag. (#2787)
• 🐛 iOS builds will no longer skip repair-wheel-command if it's defined in config (#2761)
• 🐛 Fix bug causing uv to fail when environments define PYTHON_VERSION or UV_PYTHON, conflicting with our venvs (#2795)
• ✨ cibuildwheel prints the selected build identifiers at the start of the build. (#2785)
• 🔐 The GitHub Action now references other actions with a full SHA (#2744)

v3.4.0

• 🌟 You can now build wheels using uv as a build frontend. This should improve performance, especially if your project has lots of build dependencies. To use, set build-frontend to uv. (#2322)
• ⚠️ We no longer support running on Travis CI. It may continue working but we don't run tests there anymore so we can't be sure. (#2682)
• ✨ Improvements to building Rust wheels on Android (#2650)
• 🛠 Update Pyodide to 0.29.3 (#2719, #2733)
• 🐛 Fix bug with the GitHub Action on Windows, where PATH was getting unnecessarily changed, causing issues with meson builds. (#2723)
• ✨ Add support for quiet setting on build and uv from the cibuildwheel build-verbosity setting. (#2737)
• 📚 Docs updates, including guidance on using Meson on Windows (#2718)

Changelog

v4.0.0rc1

14 May 2026

• 🌟 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 314.0.0a1, 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 3.15.0b1. (#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 3.14 will be available in cibuildwheel without the flag. (#2390)

• ✨ 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)

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

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

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

• 🛠 Updates dependencies and container pins (#2845, #2837, #2821, #2818, #2810, #2838, #2813)

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

• 📚 Documents platform-specific before-build configuration (#2834)

• 📚 Updates the "How it works" diagram with details of Android, iOS, and Pyodide builds (#2816)

• 📚 Adds Pyodide icon and regenerates working examples data for Android, iOS, and Pyodide (#2815, #2811)

• 📚 Links back to source in docs (#2806)

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

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

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

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