• 🌟 Added support for emulated builds! You can now build manylinux wheels on ARM64aarch64, as well as ppc64le and 's390x'. To build under emulation, register QEMU via binfmt_misc and set the CIBW_ARCHS_LINUX option to the architectures you want to run. See this FAQ entry for more information. (#482)
• ✨ Added CIBW_TEST_SKIP option. This allows you to choose certain builds whose tests you'd like to skip. This might be useful when running a slow test suite under emulation, for example. (#537)
• ✨ Added curly-{brace,bracket,paren} style globbing to CIBW_BUILD and CIBW_SKIP. This gives more expressivity, letting you do things like CIBW_BUILD=cp39-manylinux_{aarch64,ppc64le}. (#527)
• 🛠 cibuildwheel will now exit with an error if it's called with options that skip all builds on a platform. This feature can be disabled by adding --allow-empty on the command line. (#545)
