• 🌟 Adds support for cross-compiling Windows ARM64 wheels. To use this feature, add ARM64 to the CIBW_ARCHS option on a Windows Intel runner. (#1144)
• ✨ Adds support for building Linux aarch64 wheels on Circle CI. (#1307)
• ✨ Adds support for building Windows wheels on Gitlab CI. (#1295)
• ✨ Adds support for building Linux aarch64 wheels under emulation on Gitlab CI. (#1295)
• ✨ Adds the ability to test cp38-macosx_arm64 wheels on a native arm64 runner. To do this, you'll need to preinstall the (experimental) universal2 version of CPython 3.8 on your arm64 runner before invoking cibuildwheel. Note: it is not recommended to build x86_64 wheels with this setup, your wheels will have limited compatibility wrt macOS versions. (#1283)
• 🛠 Improved error messages when using custom Docker images and Python cannot be found at the correct path. (#1298)
