Sourced from joerick/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)
