Sourced from pypa/cibuildwheel's releases.

Version 2.19.0

Release post: https://iscinumpy.dev/post/cibuildwheel-2-19-0/

• 🌟 Add a Pyodide platform. Set with --platform pyodide or CIBW_PLATFORM: pyodide on Linux with a host Python 3.12 to build WebAssembly wheels. Not accepted on PyPI currently, but usable directly in a website using Pyodide, for live docs, etc. (#1456, #1859)
• 🌟 Add build[uv] backend, which will take a pre-existing uv install (or install cibuildwheel[uv]) and use uv for all environment setup and installs on Python 3.8+. This is significantly faster in most cases. (#1856)
• ✨ Add free-threaded macOS builds and update CPython to 3.13.0b2. (#1854)
• 🐛 Issue copying a wheel to a non-existent output dir fixed. (#1851, #1862)
• 🐛 Better determinism for the test environment seeding. (#1835)
• 🛠 VIRTUAL_ENV variable now set. (#1842)
• 🛠 Remove a pip<21.3 workaround. (#1842)
• 🛠 Error handling was refactored to use exceptions. (#1719)
• 🛠 Hardcoded paths in tests avoided. (#1834)
• 🛠 Single Python tests made more generic. (#1835)
• 🛠 Sped up our ci by splitting up emulation tests. (#1839)

v2.18.1

• 🌟 Add free-threaded Linux and Windows builds for 3.13. New identifiers cp313t-*, new option CIBW_FREE_THREADED_SUPPORT/tool.cibuildwheel.free-threaded-support required to opt-in. See the docs for more information. (#1831)
• ✨ The container-engine is now a build (non-global) option. (#1792)
• 🛠 The build backend for cibuildwheel is now hatchling. (#1297)
• 🛠 Significant improvements and modernization to our noxfile. (#1823)
• 🛠 Use pylint's new GitHub Actions reporter instead of a custom matcher. (#1823)
• 🛠 Unpin virtualenv updates for Python 3.7+ (#1830)
• 🐛 Fix running linux tests from Windows or macOS ARM. (#1788)
• 📚 Fix our documentation build. (#1821)
