- 🌟 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`](https://cibuildwheel.pypa.io/en/stable/options/#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)
- 🐛 Fix bug with the GitHub Action on Windows, where PATH was getting unnecessarily changed, causing issues with meson builds. (#2723)
- 🐛 Fix an incompatibility with Docker v29 (#2660)
- ✨ Adds `test-runtime` option, to customise how tests on simulated/emulated environments are run (#2636)
- ✨ Adds support for new `manylinux_2_35` images on 32-bit ARM `armv7l`, offering better C++20 compatibility (#2656)
- ✨ `build[uv]` is now supported on Android (#2587)
- ✨ You can now install extras (such as `uv`) with a simple option on the GitHub Action (#2630)
- ✨ `{project}` and `{package}` placeholders are now supported in `repair-wheel-command` (#2589)
- 🛠 The versions set with `dependency-versions` no longer constrain packages specified by your `build-system.requires`. Previously, on platforms other than Linux, the constraints in this option would remain in the environment during the build. This has been tidied up make behaviour more consistent between platforms, and to prevent version conflicts. (#2583)
- 🛠 Improve the handling of `test-command` on Android, enabling more options to be passed (#2590)
- ✨ Adds GraalPy v25 (Python 3.12) support (#2597)
- 🛠 Update to CPython 3.14.0rc3 (#2602)
- 🛠 Adds CPython 3.14.0 prerelease support for Android, and a number of improvements to Android builds (#2568, #2591)
- 🛠 Improvements to testing on Android, passing environment markers when installing the venv, and providing more debug output when build-verbosity is set (#2575)
- ⚠️ PyPy 3.10 was moved to `pypy-eol` in the `enable` option, as it is now end-of-life. (#2521)
- 🌟 CPython 3.14 wheels are now built by default - without the `"cpython-prerelease"``enable` set. It's time to build and upload these wheels to PyPI! This release includes CPython 3.14.0rc1, which is guaranteed to be ABI compatible with the final release. (#2507) Free-threading is no longer experimental in 3.14, so you have to skip it explicitly with `'cp31?t-*'` if you don't support it yet. (#2503)
- 🌟 Adds the ability to [build wheels for Android](https://cibuildwheel.pypa.io/en/stable/platforms/#android)! Set the [`platform` option](https://cibuildwheel.pypa.io/en/stable/options/#platform) to `android` on Linux or macOS to try it out! (#2349)
- 🌟 Adds Pyodide 0.28, which builds 3.13 wheels (#2487)
- ✨ Support for 32-bit `manylinux_2_28` (now a consistent default) and `manylinux_2_34` added (#2500)
- 🛠 Improved summary, will also use markdown summary output on GHA (#2469)
- 🛠 The riscv64 images now have a working default (as they are now part of pypy/manylinux), but are still experimental (and behind an `enable`) since you can't push them to PyPI yet (#2506)
- 🛠 Fixed a typo in the 3.9 MUSL riscv64 identifier (`cp39-musllinux_ricv64` -> `cp39-musllinux_riscv64`) (#2490)
- 🛠 Mistyping `--only` now shows the correct possibilities, and even suggests near matches on Python 3.14+ (#2499)
- 🛠 Only support one output from the repair step on linux like other platforms; auditwheel fixed this over four years ago! (#2478)
- 🌟 Adds the ability to [build wheels for iOS](https://cibuildwheel.pypa.io/en/stable/platforms/#ios)! Set the [`platform` option](https://cibuildwheel.pypa.io/en/stable/options/#platform) to `ios` on a Mac with the iOS toolchain to try it out! (#2286, #2363, #2432)
- 🌟 Adds support for the GraalPy interpreter! Enable for your project using the [`enable` option](https://cibuildwheel.pypa.io/en/stable/options/#enable). (#1538, #2411, #2414)
- ✨ Adds CPython 3.14 support, under the [`enable` option](https://cibuildwheel.pypa.io/en/stable/options/#enable) `cpython-prerelease`. This version of cibuildwheel uses 3.14.0b2. (#2390)
_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 the [test-sources option](https://cibuildwheel.pypa.io/en/stable/options/#test-sources), which copies files and folders into the temporary working directory we run tests from. (#2062, #2284, #2420, #2437)
This is particularly important for iOS builds, which do not support placeholders in the `test-command`, but can also be useful for other platforms.
- ✨ Improves support for Pyodide builds and adds the experimental [`pyodide-version`](https://cibuildwheel.pypa.io/en/stable/options/#pyodide-version) option, which allows you to specify the version of Pyodide to use for builds. (#2002)
- ✨ Add `pyodide-prerelease` [enable](https://cibuildwheel.pypa.io/en/stable/options/#enable) option, with an early build of 0.28 (Python 3.13). (#2431)
- ✨ Adds the [`test-environment`](https://cibuildwheel.pypa.io/en/stable/options/#test-environment) option, which allows you to set environment variables for the test command. (#2388)
- ✨ Adds the [`xbuild-tools`](https://cibuildwheel.pypa.io/en/stable/options/#xbuild-tools) option, which allows you to specify tools safe for cross-compilation. Currently only used on iOS; will be useful for Android in the future. (#2317)
- 🛠 The default [manylinux image](https://cibuildwheel.pypa.io/en/stable/options/#linux-image) has changed from `manylinux2014` to `manylinux_2_28`. (#2330)
- 🛠 EOL images `manylinux1`, `manylinux2010`, `manylinux_2_24` and `musllinux_1_1` can no longer be specified by their shortname. The full OCI name can still be used for these images, if you wish. (#2316)
- 🛠 Invokes `build` rather than `pip wheel` to build wheels by default. You can control this via the [`build-frontend`](https://cibuildwheel.pypa.io/en/stable/options/#build-frontend) option. You might notice that you can see your build log output now! (#2321)
- 🛠 Build verbosity settings have been reworked to have consistent meanings between build backends when non-zero. (#2339)
- 🛠 Removed the `CIBW_PRERELEASE_PYTHONS` and `CIBW_FREE_THREADED_SUPPORT` options - these have been folded into the [`enable`](https://cibuildwheel.pypa.io/en/stable/options/#enable) option instead. (#2095)
- ⚠️ Dropped support for building Python 3.6 and 3.7 wheels. If you need to build wheels for these versions, use cibuildwheel v2.23.3 or earlier. (#2282)
- ⚠️ The minimum Python version required to run cibuildwheel is now Python 3.11. You can still build wheels for Python 3.8 and newer. (#1912)
- ⚠️ 32-bit Linux wheels no longer built by default - the [arch](https://cibuildwheel.pypa.io/en/stable/options/#archs) was removed from `"auto"`. It now requires explicit `"auto32"`. Note that modern manylinux images (like the new default, `manylinux_2_28`) do not have 32-bit versions. (#2458)
- ⚠️ PyPy wheels no longer built by default, due to a change to our options system. To continue building PyPy wheels, you'll now need to set the [`enable` option](https://cibuildwheel.pypa.io/en/stable/options/#enable) to `pypy` or `pypy-eol`. (#2095)
- ⚠️ Dropped official support for Appveyor. If it was working for you before, it will probably continue to do so, but we can't be sure, because our CI doesn't run there anymore. (#2386)
- 🐛 Workaround an issue with pyodide builds when running cibuildwheel with a Python that was installed via UV (#2328 via #2331)
- 🛠 Dependency updates, including a manylinux update that fixes an ['undefined symbol' error](https://github.com/pypa/manylinux/issues/1760) in gcc-toolset (#2334)
- ⚠️ Added warnings when the shorthand values `manylinux1`, `manylinux2010`, `manylinux_2_24`, and `musllinux_1_1` are used to specify the images in linux builds. The shorthand to these (unmaintainted) images will be removed in v3.0. If you want to keep using these images, explicitly opt-in using the full image URL, which can be found in [this file](https://github.com/pypa/cibuildwheel/blob/v2.23.1/cibuildwheel/resources/pinned_docker_images.cfg). (#2312)
- 🛠 Dependency updates, including a manylinux update which fixes an [issue with rustup](https://github.com/pypa/cibuildwheel/issues/2303). (#2315)
- ✨ Adds official support for the new GitHub Actions Arm runners. In fact these worked out-of-the-box, now we include them in our tests and example configs. (#2135 via #2281)
- ✨ Adds support for building PyPy 3.11 wheels (#2268 via #2281)
- 🛠 Adopts the beta pypa/manylinux image for armv7l builds (#2269 via #2281)
- 🛠 Dependency updates, including Pyodide 0.27 (#2117 and #2281)
- 🌟 Added a new `CIBW_ENABLE`/`enable` feature that replaces `CIBW_FREETHREADED_SUPPORT`/`free-threaded-support` and `CIBW_PRERELEASE_PYTHONS` with a system that supports both. In cibuildwheel 3, this will also include a PyPy setting and the deprecated options will be removed. (#2048)
- 🌟 [Dependency groups](https://peps.python.org/pep-0735/) are now supported for tests. Use `CIBW_TEST_GROUPS`/`test-groups` to specify groups in `[dependency-groups]` for testing. (#2063)
- 🌟 Support for the experimental Ubuntu-based ARMv7l manylinux image (#2052)
- ✨ Show a warning when cibuildwheel is run from Python 3.10 or older; cibuildwheel 3.0 will require Python 3.11 or newer as host (#2050)
- 🐛 Fix issue with stderr interfering with checking the docker version (#2074)
- 🛠 Python 3.9 is now used in `CIBW_BEFORE_ALL`/`before-all` on linux, replacing 3.8, which is now EoL (#2043)
- 🛠 Error messages for producing a pure-Python wheel are slightly more informative (#2044)
- 🛠 Better error when `uname -m` fails on ARM (#2049)
- 🛠 Better error when repair fails and docs for abi3audit on Windows (#2058)
- 🛠 Better error when `manylinux-interpreters ensure` fails (#2066)
- 🛠 Update Pyodide to 0.26.4, and adapt to the unbundled pyodide-build (now 0.29) (#2090)
- 🛠 Now cibuildwheel uses dependency-groups for development dependencies (#2064, #2085)
- 📚 Docs updates and tidy ups (#2061, #2067, #2072)
- ✨ Adds support for building 32-bit armv7l wheels on musllinux. On a Linux system with emulation set up, set [CIBW_ARCHS](https://cibuildwheel.pypa.io/en/stable/options/#archs) to `armv7l` on Linux to try it out if you're interested! (#2017)
- 🐛 Fix Linux Podman builds on some systems (#2016)
- ✨ Adds official support for running on Python 3.13 (#2026)
- 🛠 Update CPython 3.13 to 3.13.0rc3 (#2029)
Note: the default [manylinux image](https://cibuildwheel.pypa.io/en/stable/options/#linux-image) is **scheduled to change** from `manylinux2014` to `manylinux_2_28` in a cibuildwheel release on or after **6th May 2025** - you can set the value now to avoid getting upgraded if you want. (#1992)
- ⚠️ Update CPython 3.12 to 3.12.6, which changes the macOS minimum deployment target on CPython 3.12 from macOS 10.9 to macOS 10.13 (#1998)
- 🛠 Changes the behaviour when inheriting `config-settings` in TOML overrides - rather than extending each key, which is rarely useful, individual keys will override previously set values. (#1803)
- 🛠 Update CPython 3.13 to 3.13.0rc2 (#1998)
- ✨ Adds support for multiarch OCI images (#1961)
- 🐛 Fixes some bugs building Linux wheels on macOS. (#1961)
- ⚠️ Changes the minimum version of Docker/Podman to Docker API version 1.43, Podman API version 3. The only mainstream runner this should affect is Travis Graviton2 runners - if so you can [upgrade your version of Docker](https://github.com/pypa/cibuildwheel/pull/1961#issuecomment-2304060019). (#1961)
- 🌟 CPython 3.13 wheels are now built by default - without the `CIBW_PRERELEASE_PYTHONS` flag. It's time to build and upload these wheels to PyPI! This release includes CPython 3.13.0rc1, which is guaranteed to be ABI compatible with the final release. Free-threading is still behind a flag/config option. (#1950)
- ✨ Provide a `CIBW_ALLOW_EMPTY` environment variable as an alternative to the command line flag. (#1937)
- 🐛 Don't use uv on PyPy3.8 on Windows, it stopped working starting in 0.2.25. Note that PyPy 3.8 is EoL. (#1868)
- 🛠 Set the `VSCMD_ARG_TGT_ARCH` variable based on target arch. (#1876)
- 🛠 Undo cleaner output on pytest 8-8.2 now that 8.3 is out. (#1943)
- 📚 Update examples to use Python 3.12 on host (cibuildwheel will require Python 3.11+ on the host machine starting in October 2024) (#1919)
- 🌟 Add 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)
- 🌟 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](https://cibuildwheel.pypa.io/en/stable/options/#free-threaded-support) 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)
- ✨ Adds CPython 3.13 support, under the prerelease flag [CIBW_PRERELEASE_PYTHONS](https://cibuildwheel.pypa.io/en/stable/options/#prerelease-pythons). This version of cibuildwheel uses 3.13.0b1. Free-threading mode is not available yet (#1657), waiting on official binaries (planned for beta 2) and pip support.
_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 3.13 will be available in cibuildwheel without the flag._ (#1815)
- 🌟 Adds the ability to inherit configuration in TOML overrides. This makes certain configurations much simpler. If you're overriding an option like `before-build` or `environment`, and you just want to add an extra command or environment variable, you can just append (or prepend) to the previous config. See [the docs](https://cibuildwheel.pypa.io/en/stable/options/#inherit) for more information. (#1730)
- 🌟 Adds official support for native `arm64` macOS GitHub runners. To use them, just specify `macos-14` as an `os` of your job in your workflow file. You can also keep `macos-13` in your build matrix to build `x86_64`. Check out the new [GitHub Actions example config](https://cibuildwheel.pypa.io/en/stable/setup/#github-actions).
- ✨ You no longer need to specify `--platform` to run cibuildwheel locally! Instead it will detect your platform automatically. This was a safety feature, no longer necessary. (#1727)
- 🛠 Removed setuptools and wheel pinned versions. This only affects old-style projects without a `pyproject.toml`, projects with `pyproject.toml` are already getting fresh versions of their `build-system.requires` installed into an isolated environment. (#1725)
- 🛠 Improve how the GitHub Action passes arguments (#1757)
- 🛠 Remove a system-wide install of pipx in the GitHub Action (#1745)
- 🐛 No longer will cibuildwheel override the `PIP_CONSTRAINT` environment variable when using the `build` frontend. Instead it will be extended. (#1675)
- 🐛 Fix a bug where building and testing both `x86_86` and `arm64` wheels on the same runner caused the wrong architectures in the test environment (#1750)
- 🐛 Fix a bug that prevented testing a CPython 3.8 wheel targeting macOS 11+ on `x86_64` (#1768)
- 🛠 Adds the ability to disable mounting the host filesystem in containers to `/host`, through the `disable_host_mount` suboption on [`CIBW_CONTAINER_ENGINE`](https://cibuildwheel.pypa.io/en/stable/options/#container-engine).
- ✨ Adds a debug option [`CIBW_DEBUG_KEEP_CONTAINER`](https://cibuildwheel.pypa.io/en/stable/options/#cibw_debug_keep_container) to stop cibuildwheel deleting build containers after the build finishes. (#1620)
- 📚 Adds support for `[tool.cibuildwheel]` checking by adding a schema compatible with the [validate-pyproject](https://github.com/abravalheri/validate-pyproject/) tool (#1622, #1628, #1629)
- 🐛 Fix parsing of `CIBW_CONTAINER_ENGINE` and `CIBW_BUILD_FRONTEND` options to not break arguments on `:` characters (#1621)
- 🐛 Fix the evaluation order of `CIBW_ENVIRONMENT` and `CIBW_ENVIRONMENT_PASS` so that `CIBW_ENVIRONMENT` assignments can reference environment variables passed through from the host machine. (#1617)
- 🛠 Supports manylinux images' deferred installation of interpreters through the `manylinux-interpreters` tool (#1630)
- ✨ Add the ability to pass additional flags to a build frontend through the [CIBW_BUILD_FRONTEND](https://cibuildwheel.pypa.io/en/stable/options/#build-frontend) option (#1588).
- ✨ The environment variable SOURCE_DATE_EPOCH is now automatically passed through to container Linux builds (useful for [reproducible builds](https://reproducible-builds.org/docs/source-date-epoch/)!) (#1589)
- 🛠 Updates the prerelease CPython 3.12 version to 3.12.0rc2 (#1604)
- 🌟 CPython 3.12 wheels are now built by default - without the CIBW_PRERELEASE_PYTHONS flag. It's time to build and upload these wheels to PyPI! This release includes CPython 3.12.0rc1, which is guaranteed to be ABI compatible with the final release. (#1565)
- ✨ Adds musllinux_1_2 support - this allows packagers to build for musl-based Linux distributions on a more recent Alpine image, and a newer musl libc. (#1561)
- ⚠️ Removed support for running cibuildwheel in Python 3.7. Python 3.7 is EOL. However, cibuildwheel continues to build Python 3.7 wheels for the moment. (#1175)
- 🛠 Updates the prerelease CPython 3.12 version to 3.12.0b2. (#1516)
- 🛠 Adds a moving `v<major>.<minor>` tag for use in GitHub Actions workflow files. If you use this, you'll get the latest patch release within a minor version. Additionally, Dependabot won't send you PRs for patch releases. (#1517)
- ✨ Adds CPython 3.12 support, under the prerelease flag [CIBW_PRERELEASE_PYTHONS](https://cibuildwheel.pypa.io/en/stable/options/#prerelease-pythons). This version of cibuildwheel uses 3.12.0b1.
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 3.12 will be available in cibuildwheel without the flag. (#1507)
- ✨ Adds the ability to pass arguments to the container engine when the container is created, using the [CIBW_CONTAINER_ENGINE](https://cibuildwheel.pypa.io/en/stable/options/#container-engine) option. (#1499)
- ✨ Adds support for PyPy arm64 wheels. This means that you can build PyPy wheels for Apple Silicon machines. Cross-compilation is not supported for these wheels, so you'll have to build on an Apple Silicon machine. (#1372)
- 🛠 Pinned version updates, including PyPy to v7.3.11 and setuptools to 66.0.0.
- ✨ Improves the 'build options' log output that's printed at the start of each run (#1352)
- ✨ Added a friendly error message to a common misconfiguration of the `CIBW_TEST_COMMAND` option - not specifying path using the `{project}` placeholder (#1336)
- 🛠 The GitHub Action now uses Powershell on Windows to avoid occasional incompabilities with bash (#1346)
- 🛠 Updates CPython 3.11 to 3.11.0 - final release (#1327)
- 🛠 Simplify the default macOS repair command (#1322)
- 🛠 Fix the default `MACOSX_DEPLOYMENT_TARGET` on arm64 (#1312)
- 🛠 Hide irrelevant pip warnings on linux (#1311)
- 🐛 Fix a bug that caused the stdout and stderr of commands in containers to be in the wrong order Previously, stdout could appear after stderr. (#1324)
- 📚 Added [a FAQ entry](https://cibuildwheel.pypa.io/en/stable/faq/#macos-building-cpython-38-wheels-on-arm64) describing how to perform native builds of CPython 3.8 wheels on Apple Silicon. (#1323)
- 🌟 Adds support for cross-compiling Windows ARM64 wheels. To use this feature, add `ARM64` to the [CIBW_ARCHS](https://cibuildwheel.pypa.io/en/stable/options/#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](https://www.python.org/ftp/python/3.8.10/python-3.8.10-macos11.pkg) 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)
- 📚 Sample configs for Azure Pipelines and Travis CI updated (#1296)
- 📚 Other docs improvements - including more information about using Homebrew for build dependencies (#1290)
- 🌟 Adds support for [building wheels on Cirrus CI](https://cibuildwheel.pypa.io/en/stable/setup/#cirrus-ci). This is exciting for us, as it's the first public CI platform that natively supports macOS Apple Silicon (aka. M1, `arm64`) runners. As such, it's the first platform that you can natively build _and test_ macOS `arm64` wheels. It also has native Linux ARM (aarch64) runners, for fast, native builds there. (#1191)
- 🌟 Adds support for running cibuildwheel on Apple Silicon machines. For a while, we've supported cross-compilation of Apple Silicon wheels on `x86_64`, but now that we have Cirrus CI we can run our test suite and officially support running cibuildwheel on `arm64`. (#1191)
- ✨ Adds the `--only` [command line option](https://cibuildwheel.pypa.io/en/stable/options/#command-line), to specify a single build to run. Previously, it could be cumbersome to set all the build selection options to target a specific build - for example, you might have to run something like `CIBW_BUILD=cp39-manylinux_x86_64 cibuildwheel --platform linux --archs x86_64`. The new `--only` option overrides all the build selection options to simplify running a single build, which now looks like `cibuildwheel --only cp39-manylinux_x86_64`. (#1098)
- ✨ Adds the [`CIBW_CONFIG_SETTINGS`](https://cibuildwheel.pypa.io/en/stable/options/#config-settings) option, so you can pass arguments to your package's build backend (#1244)
- 🌟 CPython 3.11 wheels are now built by default - without the CIBW_PRERELEASE_PYTHONS flag. It's time to build and upload these wheels to PyPI! This release includes CPython 3.11.0rc1, which is guaranteed to be ABI compatible with the final release. (#1226)
- ⚠️ Removed support for running cibuildwheel in Python 3.6. Python 3.6 is EOL. However, cibuildwheel continues to build CPython 3.6 wheels for the moment. (#1175)
- ✨ Improved error messages when misspelling TOML options, suggesting close matches (#1205)
- 🛠 When running on Apple Silicon (so far, an unsupported mode of operation), cibuildwheel no longer builds universal2 wheels by default - just arm64. See [#1204](https://github.com/pypa/cibuildwheel/issues/1204) for discussion. We hope to release official support for native builds on Apple Silicon soon! (#1217)
- 🐛 Fix a bug when building CPython 3.8 wheels on an Apple Silicon machine where testing would always fail. cibuildwheel will no longer attempt to test the arm64 part of CPython 3.8 wheels because we use the x86_64 installer of CPython 3.8 due to its macOS system version backward-compatibility. See [#1169](https://github.com/pypa/cibuildwheel/pull/1169) for more details. (#1171)
- 🛠 Update the prerelease CPython 3.11 to 3.11.0b4. (#1180)
- 🛠 The GitHub Action will ensure a compatible version of Python is installed on the runner (#1114)
- ✨ You can now run cibuildwheel on Podman, as an alternate container engine to Docker (which remains the default). This is useful in environments where a Docker daemon isn't available, for example, it can be run inside a Docker container, or without root access. To use Podman, set the [`CIBW_CONTAINER_ENGINE`](https://cibuildwheel.pypa.io/en/stable/options/#container-engine) option. (#966)
- ✨ Adds support for building `py3-none-{platform}` wheels. This works the same as ABI3 - wheels won't be rebuilt, but tests will still be run across all selected versions of Python.
These wheels contain native extension code, but don't use the Python APIs. Typically, they're bridged to Python using a FFI module like [ctypes](https://docs.python.org/3/library/ctypes.html) or [cffi](https://cffi.readthedocs.io/en/latest/). Because they don't use Python ABI, the wheels are more compatible - they work across many Python versions.
Check out this [example ctypes project](https://github.com/joerick/python-ctypes-package-sample) to see an example of how it works. (#1151)
- 🌟 Added support for the new `manylinux_2_28` images. These new images are based on AlmaLinux, the community-driven successor to CentOS, unlike manylinux_2_24, which was based on Debian. To build on these images, set your [`CIBW_MANYLINUX_*_IMAGE`](https://cibuildwheel.pypa.io/en/stable/options/#linux-image) option to `manylinux_2_28`. (#1026)
- 🌟 Added the ability to test building wheels on CPython 3.11! Because CPython 3.11 is in beta, these wheels should not be distributed, because they might not be compatible with the final release, but it's available to build for testing purposes. Use the flag [`--prerelease-pythons` or `CIBW_PRERELEASE_PYTHONS`](https://cibuildwheel.pypa.io/en/stable/options/#prerelease-pythons) to test. This version of cibuildwheel includes CPython 3.11.0b1. (#1109)
- 📚 Added an interactive diagram showing how cibuildwheel works to the [docs](https://cibuildwheel.pypa.io/en/stable/#how-it-works) (#1100)
- ✨ Added support for building ABI3 wheels. cibuildwheel will now recognise when an ABI3 wheel was produced, and skip subsequent build steps where the previously built wheel is compatible. Tests still will run on all selected versions of Python, using the ABI3 wheel. Check [this entry](https://cibuildwheel.pypa.io/en/stable/faq/#abi3) in the docs for more info. (#1091)
- ✨ You can now build wheels directly from sdist archives, in addition to source directories. Just call cibuildwheel with an sdist argument on the command line, like `cibuildwheel mypackage-1.0.0.tar.gz`. For more details, check the [`--help` output](https://cibuildwheel.pypa.io/en/stable/options/#command-line) (#1096)
- ✨ cibuildwheel now supports running locally on Windows and macOS (as well as Linux). On macOS, you'll have to install the versions of Pythons that you want to use from Python.org, and cibuildwheel will use them. On Windows, cibuildwheel will install it's own versions of Python. Check out [the documentation](https://cibuildwheel.pypa.io/en/stable/setup/#local) for instructions. (#974)
- ✨ Added support for building PyPy 3.9 wheels. (#1031)
- ✨ Listing at the end of the build now displays the size of each wheel (#975)
- 🐛 Workaround a connection timeout bug on Travis CI ppc64le runners (#906)
- 🐛 Fix an encoding error when reading setup.py in the wrong encoding (#977)
- 🛠 Setuptools updated to 61.3.0, including experimental support for reading config from pyproject.toml(PEP 621). This could change the behaviour of your build if you have a pyproject.toml with a `[project]` table, because that takes precedence over setup.py and setup.cfg. Check out the [setuptools docs](https://setuptools.pypa.io/en/latest/userguide/pyproject_config.html) and the [project metadata specification](https://packaging.python.org/en/latest/specifications/declaring-project-metadata/) for more info.
- 🐛 Setting pip options like `PIP_USE_DEPRECATED` in `CIBW_ENVIRONMENT` no longer adversely affects cibuildwheel's ability to set up a Python environment (#956)
- 📈 cibuildwheel now defaults to manylinux2014 image for linux builds, rather than manylinux2010. If you want to stick with manylinux2010, it's simple to set this using [the image options](https://cibuildwheel.pypa.io/en/stable/options/#linux-image). (#926)
- ✨ You can now pass environment variables from the host machine into the Docker container during a Linux build. Check out [the docs for `CIBW_ENVIRONMENT_PASS_LINUX `](https://cibuildwheel.pypa.io/en/stable/options/#environment-pass) for the details. (#914)
- ✨ Added support for building PyPy 3.8 wheels. (#881)
- ✨ Added support for building Windows arm64 CPython wheels on a Windows arm64 runner. We can't test this in CI yet, so for now, this is experimental. (#920)
- 🛠 Changed the escaping behaviour inside cibuildwheel's option placeholders e.g. `{project}` in `before_build` or `{dest_dir}` in `repair_wheel_command`. This allows bash syntax like `${SOME_VAR}` to passthrough without being interpreted as a placeholder by cibuildwheel. See [this section](https://cibuildwheel.pypa.io/en/stable/options/#placeholders) in the docs for more info. (#889)
- 🛠 Pip updated to 21.3, meaning it now defaults to in-tree builds again. If this causes an issue with your project, setting environment variable `PIP_USE_DEPRECATED=out-of-tree-build` is available as a temporary flag to restore the old behaviour. However, be aware that this flag will probably be removed soon. (#881)
- 🐛 You can now access the current Python interpreter using `python3` within a build on Windows (#917)
- 🛠 Added a `config-file` option on the GitHub Action to specify something other than pyproject.toml in your GitHub Workflow file. (#883)
- 🐛 Fix missing resources in sdist and released wheel on PyPI. We've also made some internal changes to our release processes to make them more reliable. (#893, #894)
- 🌟 Added support for [musllinux](https://www.python.org/dev/peps/pep-0656/). Support for this new wheel format lets projects build wheels for Linux distributions that use [musl libc](https://musl.libc.org/), notably, [Alpine](https://alpinelinux.org/) Docker containers. (#768)
Musllinux builds are enabled by default. If you're not ready to build musllinux, add `*-musllinux_*` to your [`CIBW_SKIP`/`skip`](https://cibuildwheel.pypa.io/en/stable/options/#build-skip) option. Or, you might have to make some changes to your options - to simplify that process, you can use...
You can now set build options for any subset of your builds using a match pattern. So, for example, you can customise CPython 3.8 builds with an override on `cp38-*` or musllinux builds by selecting `*musllinux*`. Check out [the docs](https://cibuildwheel.pypa.io/en/stable/options/#overrides) for more info on the specifics.
- 🛠 Setting an empty string for the [`CIBW_*_IMAGE`](https://cibuildwheel.pypa.io/en/stable/options/#manylinux-image) option will now fallthrough to the config file or cibuildwheel's default, rather than causing an error. This makes the option easier to use in CI build matrices. (#829)
- ✨ Corresponding with the release of CPython 3.10.0rc1, which is ABI stable, cibuildwheel now builds CPython 3.10 by default - without the CIBW_PRERELEASE_PYTHONS flag.
<sup>Note: v2.1.0 was a bad release, it was yanked from PyPI.</sup>
- 🌟 You can now configure cibuildwheel options inside your project's `pyproject.toml`! Environment variables still work of course. Check out the [documentation](https://cibuildwheel.pypa.io/en/stable/options/#setting-options) for more info.
- 🌟 Added support for building wheels with [build](https://github.com/pypa/build), as well as pip. This feature is controlled with the [`CIBW_BUILD_FRONTEND`](https://cibuildwheel.pypa.io/en/stable/options/#build-frontend) option.
- 🌟 Added the ability to test building wheels on CPython 3.10! Because CPython 3.10 is in beta, these wheels should not be distributed, because they might not be compatible with the final release, but it's available to build for testing purposes. Use the flag [`--prerelease-pythons` or `CIBW_PRERELEASE_PYTHONS`](https://cibuildwheel.pypa.io/en/stable/options/#prerelease-pythons) to test. (#675) This version of cibuildwheel includes CPython 3.10.0b4.
- ⚠️ **Removed support for building Python 2.7 and Python 3.5 wheels**, for both CPython and PyPy. If you still need to build on these versions, please use the latest v1.x version. (#596)
- ✨ Added the ability to build CPython 3.8 wheels for Apple Silicon. (#704)
- 🛠 Update to the latest build dependencies, including Auditwheel 4. (#633)
- 🛠 Use the unified pypa/manylinux images to build PyPy (#671)

- 🛠 Update manylinux pins to the last version containing Python 2.7 and 3.5. (#674)
- ⚠️ cibuildwheel will no longer build Windows 2.7 wheels, unless you specify a custom toolchain using `DISTUTILS_USE_SDK=1` and `MSSdk=1`. This is because Microsoft have stopped distributing Visual C++ Compiler for Python 2.7. See [this FAQ entry](https://cibuildwheel.pypa.io/en/stable/faq/#windows-and-python-27) for more details. (#649)

### 0.9.1
_18 June 2018_
- 🛠 Removed the need to use `{python}` and `{pip}` in `CIBW_BEFORE_BUILD` statements, by ensuring the correct version is always on the path at `python` and `pip` instead. (#60)
- 🛠 We now patch the _ssl module on Python 3.4 and 3.5 so these versions can still make SSL web requests using TLS 1.2 while building. (#71)
- 🐛 macOS: Fix brew Python3 version problems in the CI
### 0.7.0
_7 January 2018_
- ✨ You can now specify a custom docker image using the `CIBW_MANYLINUX1_X86_64_IMAGE` and `CIBW_MANYLINUX1_I686_IMAGE` options. (#46)
- 🐛 Fixed a bug where cibuildwheel would download and build a package from PyPI(!) instead of building the package on the local machine. (#51)
### 0.6.0
_9 October 2017_
- ✨ On the Linux build, the host filesystem is now accessible via `/host` (#36)
- 🐛 Fixed a bug where setup.py scripts would run the wrong version of Python when running subprocesses on Linux (#35)
### 0.5.1
_10 September 2017_
- 🐛 Fixed a couple of bugs on Python 3.
- ✨ Added experimental support for Mac builds on [Bitrise.io](https://www.bitrise.io)
### 0.5.0
_7 September 2017_
- ✨ `CIBW_ENVIRONMENT` added. You can now set environment variables for each build, even within the Docker container on Linux. This is a big one! (#21)
- ✨ `CIBW_BEFORE_BUILD` now runs in a system shell on all platforms. You can now do things like `CIBW_BEFORE_BUILD="cmd1 && cmd2"`. (#32)
### 0.4.1
_14 August 2017_
- 🐛 Fixed a bug on Windows where subprocess' output was hidden (#23)
- 🐛 Fixed a bug on AppVeyor where logs would appear in the wrong order due to output buffering (#24, thanks @YannickJadoul!)
### 0.4.0
_23 July 2017_
- 🐛 Fixed a bug that was increasing the build time by building the wheel twice. This was a problem for large projects that have a long build time. If you're upgrading and you need the old behaviour, use `CIBW_BEFORE_BUILD={pip} install .`, or install exactly the dependencies you need in `CIBW_BEFORE_BUILD`. See #18.
### 0.3.0
_27 June 2017_
- ⚠️ Removed Python 2.6 support on Linux (#12)
### 0.2.1
_11 June 2017_
- 🛠 Changed the build process to install the package before building the wheel - this allows direct dependencies to be installed first (#9, thanks @tgarc!)
- ✨ Added Python 3 support for the main process, for systems where Python 3 is the default (#8, thanks @tgarc).
