# Changelog
### v3.4.0
_5 March 2026_
- 🌟 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)
- ✨ 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)
### v3.3.1
_5 January 2026_
- 🛠 Update dependencies and container pins, including updating to CPython 3.14.2. (#2708)
### v3.3.0
_12 November 2025_
- 🐛 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)

### v3.1.0
_23 July 2025_
- 🌟 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)
- 💼 We now use pattern matching extensively (#2434)
- 📚 We now have platform maintainers for our special platforms and interpreters! (#2481)
### v3.0.1
_5 July 2025_
- 🛠 Updates CPython 3.14 prerelease to 3.14.0b3 (#2471)
- ✨ Adds a CPython 3.14 prerelease iOS build (only when prerelease builds are [enabled](https://cibuildwheel.pypa.io/en/stable/options/#enable)) (#2475)
### v3.0.0
_11 June 2025_
See @henryiii's [release post](https://iscinumpy.dev/post/cibuildwheel-3-0-0/) for more info on new features!
- 🌟 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.
- ✨ Adds [`dependency-versions`](https://cibuildwheel.pypa.io/en/stable/options/#dependency-versions) inline syntax (#2122)
- ✨ 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)
- 🛠 Build environments no longer have setuptools and wheel preinstalled. (#2329)
- 🛠 Use the standard Schema line for the integrated JSONSchema. (#2433)
- ⚠️ 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)
- 📚 A reorganisation of the docs, and numerous updates. (#2280)
- 📚 Use Python 3.14 color output in docs CLI output. (#2407)
- 📚 Docs now primarily use the pyproject.toml name of options, rather than the environment variable name. (#2389)
- 📚 README table now matches docs and auto-updates. (#2427, #2428)
### v2.23.3

_15 March 2025_
- ⚠️ 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)

- 🛠 Adopts the beta pypa/manylinux image for armv7l builds (#2269 via #2281)
- 🛠 Dependency updates, including Pyodide 0.27 (#2117 and #2281)
### v2.22.0
_23 November 2024_
- 🌟 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)

- 📚 Docs updates and tidy ups (#2035)
### v2.21.2
_2 October 2024_
- ✨ 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)
### v2.21.1
_16 September 2024_
- 🐛 Fix a bug in the Linux build, where files copied to the container would have invalid ownership permissions (#2007)
- 🐛 Fix a bug on Windows where cibuildwheel would call upon `uv` to install dependencies for versions of CPython that it does not support (#2005)
- 🐛 Fix a bug where `uv 0.4.10` would not use the right Python when testing on Linux. (#2008)
- 🛠 Bump our documentation pins, fixes an issue with a missing package (#2011)
### v2.21.0
_13 September 2024_
- ⚠️ 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)
### v2.20.0
_4 August 2024_
- 🌟 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)

- 📚 Remove nosetest from our docs. (#1821)
- 📚 Document the macOS ARM workaround for 3.8 on GHA. (#1871)
- 📚 GitLab CI + macOS is now a supported platform with an example. (#1911)
### v2.19.1
_13 June 2024_
- 🐛 Don't require setup-python on GHA for Pyodide (#1868)
- 🐛 Specify full python path for uv (fixes issue in 0.2.10 & 0.2.11) (#1881)
- 🛠 Update for pip 24.1b2 on CPython 3.13. (#1879)
- 🛠 Fix a warning in our schema generation script. (#1866)
- 🛠 Cleaner output on pytest 8-8.2. (#1865)
### v2.19.0
_10 June 2024_
See the [release post](https://iscinumpy.dev/post/cibuildwheel-2-19-0/) for more info on new features!
- 🌟 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)
### v2.18.1
_20 May 2024_
- 🌟 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)
- 📚 Fix our documentation build. (#1821)
### v2.18.0
_12 May 2024_
- ✨ 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)
- ✨ Musllinux now defaults to `musllinux_1_2`. You can set the older `musllinux_1_1` via config if needed. (#1817)
- 🛠 No longer pre-seed setuptools/wheel in virtual environments (#1819)
- 🛠 Respect the constraints file when building with pip, matching build (#1818)
- 🛠 Use uv to compile our pinned dependencies, 10x faster and doesn't require special setup (#1778)
- 🐛 Fix an issue with the schema (#1788)
- 📚 Document the new delocate error checking macOS versions (#1766)
- 📚 Document Rust builds (#1816)
- 📚 Speed up our readthedocs builds with uv, 26 seconds -> 6 seconds to install dependencies (#1816)
### v2.17.0
_11 March 2024_
- 🌟 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)

### v2.15.0
_8 August 2023_
- 🌟 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)
### v2.14.1
_15 July 2023_
- 🛠 Updates the prerelease CPython 3.12 version to 3.12.0b4 (#1550)
### v2.14.0

- ⚠️ 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)
### v2.13.1
_10 June 2023_
- 🛠 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)
### v2.13.0
_28 May 2023_
- ✨ 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)
### v2.12.3

- 🐛 Fix a crash that occurred when overwriting an existing wheel on Windows. (#1464)
- 🛠 Pinned version updates, including CPython 3.10.11, 3.11.3, pip 23.1 and wheel 0.40.0.
### v2.12.1
_11 March 2023_
- 🐛 Fix a bug that prevented the use of CIBW_CONFIG_SETTINGS with the 'pip' build backend. (#1430)
### v2.12.0
_16 Jan 2023_
- ✨ 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.
### v2.11.4
_24 Dec 2022_
- 🐛 Fix a bug that caused missing wheels on Windows when a test was skipped using CIBW_TEST_SKIP (#1377)
- 🛠 Updates CPython 3.11 to 3.11.1 (#1371)

- 📚 Added a reference to abi3audit to the docs (#1347)
### v2.11.3
_5 Dec 2022_
- ✨ 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)
### v2.11.2

- 🛠 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)
- 📚 Other docs improvements
### v2.11.1
_13 October 2022_
- 🛠 Updates to the latest manylinux images, and updates CPython 3.10 to 3.10.8.
### v2.11.0
_13 October 2022_
- 🌟 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)
### v2.10.2
_25 September 2022_
- 🐛 Fix a bug that caused `win32` identifiers to fail when used with `--only`. (#1282)
- 🐛 Fix computation of `auto`/`auto64`/`auto32` archs when targeting a different platform to the one that you're running cibuildwheel on. (#1266)
- 📚 Fix an mistake in the 'how it works' diagram. (#1274)
### v2.10.1
_18 September 2022_
- 🐛 Fix a bug that stopped environment variables specified in TOML from being expanded. (#1273)
### v2.10.0
_13 September 2022_
- 🌟 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)
- 🛠 Updates the CPython 3.11 version to the latest release candidate - v3.11.0rc2. (#1265)
- 🐛 Fix a bug that can cause a RecursionError on Windows when building from an sdist. (#1253)
- 🛠 Add support for the s390x architecture on manylinux_2_28 (#1255)
### v2.9.0
_11 August 2022_
- 🌟 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)
### v2.8.1
_18 July 2022_
- 🐛 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)
- 📚 A few docs improvements
### v2.8.0
_5 July 2022_
- ✨ 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)
- 🛠 cibuildwheel will now error if multiple builds in a single run produce the same wheel filename, as this indicates a misconfiguration. (#1152)
- 📚 A few docs improvements and updates to keep things up-to-date.
### v2.7.0
_17 June 2022_
- 🌟 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)
- 🐛 Fix a bug where tests were not being run on CPython 3.11 (when CIBW_PRERELEASE_PYTHONS was set) (#1138)
- ✨ You can now build Linux wheels on Windows, as long as you have Docker installed and set to 'Linux containers' (#1117)
- 🐛 Fix a bug on macOS that caused cibuildwheel to crash trying to overwrite a previously-built wheel of the same name. (#1129)
### v2.6.1
_7 June 2022_
- 🛠 Update the prerelease CPython 3.11 to 3.11.0b3
### v2.6.0
_25 May 2022_
- 🌟 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)
### v2.5.0
_29 April 2022_
- ✨ 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)
- 🐛 Fix a bug where cibuildwheel would crash when no builds are selected and `--allow-empty` is passed (#1086)
- 🐛 Workaround a permissions issue on Linux relating to newer versions of git and setuptools_scm (#1095)
- 📚 Minor docs improvements
### v2.4.0
_2 April 2022_
- ✨ 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.
- 🛠 Many other dependency updates.
- 📚 Minor docs improvements
### v2.3.1
_14 December 2021_
- 🐛 Setting pip options like `PIP_USE_DEPRECATED` in `CIBW_ENVIRONMENT` no longer adversely affects cibuildwheel's ability to set up a Python environment (#956)
- 📚 Docs fixes and improvements
### v2.3.0
_26 November 2021_
- 📈 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)
- 📚 Improved the deployment documentation (#911)
- 🛠 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)
### v2.2.2
_26 October 2021_
- 🐛 Fix bug in the GitHub Action step causing a syntax error (#895)
### v2.2.1
_26 October 2021_
- 🛠 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)
### v2.2.0
_22 October 2021_
- 🌟 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...
- 🌟 TOML option overrides! This provides much greater flexibility in configuration via pyproject.toml. (#854)
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.
- 🛠 Added support for building PyPy wheels on macOS 11 CI runners. (#875)
- 🛠 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)
- 🛠 Support for TOML 1.0 when reading config files, via the `tomli` package. (#876)
<sup>Note: This version is not available on PyPI due to some missing resources in the release files. Please use a later version instead.</sup>
### v2.1.3
_6 October 2021_
- 🛠 Updated CPython 3.10 to the 3.10.0 final release
### v2.1.2
_14 September 2021_
- 🛠 Updated CPython 3.10 to 3.10.0rc2
- 📚 Multiple docs updates
- 🐛 Improved warnings when built binaries are bundled into the container on Linux. (#807)
### v2.1.1
_7 August 2021_
- ✨ 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>
### v2.0.1
_25 July 2021_
- 📚 Docs improvements (#767)
- 🛠 Dependency updates, including delocate 0.9.0.
### v2.0.0 🎉
_16 July 2021_
- 🌟 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)
- 🐛 Numerous bug fixes & docs improvements
### v1.12.0
_22 June 2021_
- ✨ Adds support building macOS universal2/arm64 wheels on Python 3.8.
### v1.11.1
_28 May 2021_
- ✨ cibuildwheel is now part of the PyPA!
- 📚 Minor docs changes, fixing links related to the above transition
- 🛠 Update manylinux pins to the last version containing Python 2.7 and 3.5. (#674)
### v1.11.0
_1 May 2021_
- 📚 Lots of docs improvements! (#650, #623, #616, #609, #606)
- 🐛 Fix nuget "Package is not found" error on Windows. (#653)
- ⚠️ 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)
- 🐛 Fix crash on Windows due to missing `which` command (#641).
### v1.10.0
_22 Feb 2021_
- ✨ Added `manylinux_2_24` support. To use these new Debian-based manylinux
images, set your [manylinux image](https://cibuildwheel.pypa.io/en/stable/options/#linux-image)
options to `manylinux_2_24`.
- 🛠 On macOS, we now set `MACOSX_DEPLOYMENT_TARGET` in before running
`CIBW_BEFORE_ALL`. This is useful when using `CIBW_BEFORE_ALL` to build a
shared library.
- 🛠 An empty `CIBW_BUILD` option is now the same as being unset i.e, `*`.
This makes some build matrix configuration easier. (#588)
- 📚 Neatened up documentation - added tabs to a few places (#576), fixed some
formatting issues.
### v1.9.0
_5 February 2021_
- 🌟 Added support for Apple Silicon wheels on macOS! You can now
cross-compile `universal2` and `arm64` wheels on your existing macOS Intel
runners, by setting
[CIBW_ARCHS_MACOS](https://cibuildwheel.pypa.io/en/stable/options/#archs).
Xcode 12.2 or later is required, but you don't need macOS 11.0 - you can
still build on macOS 10.15. See
[this FAQ entry](https://cibuildwheel.pypa.io/en/stable/faq/#apple-silicon)
for more information. (#484)
- 🌟 Added auto-detection of your package's Python compatibility, via declared
[`requires-python`](https://www.python.org/dev/peps/pep-0621/#requires-python)
in your `pyproject.toml`, or
[`python_requires`](https://packaging.python.org/guides/distributing-packages-using-setuptools/#python-requires)
in `setup.cfg` or `setup.py`. If your project has these set, cibuildwheel
will automatically skip builds on versions of Python that your package
doesn't support. Hopefully this makes the first-run experience of
cibuildwheel a bit easier. If you need to override this for any reason,
look at [`CIBW_PROJECT_REQUIRES_PYTHON`](https://cibuildwheel.pypa.io/en/stable/options/#requires-python).
(#536)
- 🌟 cibuildwheel can now be invoked as a native GitHub Action! You can now
invoke cibuildwheel in a GHA build step like:
```yaml
- name: Build wheels
uses: pypa/cibuildwheel@version # e.g. v1.9.0
with:
output-dir: wheelhouse
# env:
# CIBW_SOME_OPTION: value
```
This saves a bit of boilerplate, and you can [use Dependabot to keep the
pinned version up-to-date](https://cibuildwheel.pypa.io/en/stable/faq/#automatic-updates).
- ✨ Added `auto64` and `auto32` shortcuts to the
[CIBW_ARCHS](https://cibuildwheel.pypa.io/en/stable/options/#archs)
option. (#553)
- ✨ cibuildwheel now prints a list of the wheels built at the end of each
run. (#570)
- 📚 Lots of minor docs improvements.
### 1.8.0
_22 January 2021_
- 🌟 Added support for emulated builds! You can now build manylinux wheels on
ARM64`aarch64`, as well as `ppc64le` and 's390x'. To build under emulation,
register QEMU via binfmt_misc and set the
[`CIBW_ARCHS_LINUX`](https://cibuildwheel.pypa.io/en/stable/options/#archs)
option to the architectures you want to run. See
[this FAQ entry](https://cibuildwheel.pypa.io/en/stable/faq/#emulation)
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)
### 1.7.4
_2 January 2021_
- 🐛 Fix the PyPy virtualenv patch to work on macOS 10.14 (#506)
### 1.7.3
_1 January 2021_
- 🛠 Added a patch for Pypy to ensure header files are available for building
in a virtualenv. (#502)
- 🛠 Some preparatory work towards using cibuildwheel as a GitHub Action.
Check out
[the FAQ](https://cibuildwheel.pypa.io/en/stable/faq/#option-1-github-action)
for information on how to use it. We'll be fully updating the docs to this
approach in a subsequent release (#494)
### 1.7.2
_21 December 2020_
- 🛠 Update dependencies, notably wheel==0.36.2 and pip==20.3.3, and CPython to
their latest bugfix releases (#489)
- 📚 Switch to a GitHub example in the README (#479)
- 📚 Create Working Examples table, with many projects that use cibuildwheel (#474)
- 📚 Import Working Examples table and Changelog to docs

- 🛠 Update manylinux2010 image to resolve issues with 'yum' repositories
(#472)
### 1.7.0

it. (#458)
- 🛠 Update PyPy to 7.3.3 (#460)
- 🐛 Fix a bug where CIBW_BEFORE_ALL runs with a very old version of Python on
Linux. (#464)
### 1.6.4
_31 October 2020_

_20 September 2020_
- 🛠 Add PPC64LE manylinux image supporting Python 3.9. (#436)
- 📚 Add project URLs to PyPI listing (#428)
### 1.6.0
_9 September 2020_
- 🌟 Add Python 3.9 support! This initial support uses release candidate
builds. You can start publishing wheels for Python 3.9 now, ahead of
the official release. (#382)
Minor note - if you're building PPC64LE wheels, the manylinux image pinned
by this version is
[still on Python 3.9b3](https://github.com/pypa/manylinux/issues/758), not a
release candidate. We'd advise holding off on distributing 3.9 ppc64le wheels
until a subsequent version of cibuildwheel.
- 🌟 Add Gitlab CI support. Gitlab CI can now build Linux wheels, using
cibuildwheel. (#419)
- 🐛 Fix a bug that causes pyproject.toml dependencies to fail to install on
Windows (#420)
- 📚 Added some information about Windows VC++ runtimes and how they relate
to wheels.
### 1.5.5

- 🐛 Fix a bug that would cause command substitutions in CIBW_ENVIRONMENT to
produce no output on Linux (#411)
- 🐛 Fix regression (introduced in 1.5.3) which caused BEFORE_BUILD and
BEFORE_ALL to be executed in the wrong directory (#410)
### 1.5.4
_19 June 2020_

### 1.5.1
_25 June 2020_
- 🐛 Fix "OSError: [WinError 17] The system cannot move the file to a different
disk drive" on GitHub Actions (#388, #389)
### 1.5.0
_24 June 2020_
- 🌟 Add [`CIBW_BEFORE_ALL`](https://cibuildwheel.pypa.io/en/stable/options/#before-all)
option, which lets you run a command on the build machine before any wheels
are built. This is especially useful when building on Linux, to `make`
something external to Python, or to `yum install` a dependency. (#342)
- ✨ Added support for projects using pyproject.toml instead of setup.py
(#360, #358)
- ✨ Added workaround to allow Python 3.5 on Windows to pull dependencies from
pyproject.toml. (#358)
- 📚 Improved GitHub Actions examples and docs (#354, #362)
- 🐛 Ensure pip wheel uses the specified package, and doesn't build a wheel
from PyPI (#369)
- 🛠 Internal changes: using pathlib.Path, precommit hooks, testing
improvements.
### 1.4.2
_25 May 2020_
- 🛠 Dependency updates, including CPython 3.8.3 & manylinux images.
- 🛠 Lots of internal updates - type annotations and checking using mypy, and
a new integration testing system.
- ⚠️ Removed support for *running* cibuildwheel using Python 3.5. cibuildwheel
will continue to build Python 3.5 wheels until EOL.
### 1.4.1
_4 May 2020_
- 🐛 Fix a bug causing programs running inside the i686 manylinux images to
think they were running x86_64 and target the wrong architecture. (#336,
#338)
### 1.4.0
_2 May 2020_
- 🌟 Deterministic builds. cibuildwheel now locks the versions of the tools it
uses. This means that pinning your version of cibuildwheel pins the versions
of pip, setuptools, manylinux etc. that are used under the hood. This should
make things more reliable. But note that we don't control the entire build
environment on macOS and Windows, where the version of Xcode and Visual
Studio can still effect things.
This can be controlled using the [CIBW_DEPENDENCY_VERSIONS](https://cibuildwheel.pypa.io/en/stable/options/#dependency-versions)
and [manylinux image](https://cibuildwheel.pypa.io/en/stable/options/#linux-image)
options - if you always want to use the latest toolchain, you can still do
that, or you can specify your own pip constraints file and manylinux image.
(#256)
- ✨ Added `package_dir` command line option, meaning we now support building
a package that lives in a subdirectory and pulls in files from the wider
project. See [the `package_dir` option help](https://cibuildwheel.pypa.io/en/stable/options/#command-line-options)
for more information.
Note that this change makes the working directory (where you call
cibuildwheel from) relevant on Linux, as it's considered the 'project' and
will be copied into the Docker container. If your builds are slower on this
version, that's likely the reason. `cd` to your project and then call
`cibuildwheel` from there. (#319, #295)
- 🛠 On macOS, we make `MACOSX_DEPLOYMENT_TARGET` default to `10.9` if it's
not set. This should make things more consistent between Python versions.
- 🛠 Dependency updates - CPython 3.7.7, CPython 2.7.18, Pypy 7.3.1.
### 1.3.0
_12 March 2020_
- 🌟 Add support for building on GitHub Actions! Check out the
[docs](https://cibuildwheel.pypa.io/en/stable/setup/#github-actions)
for information on how to set it up. (#194)
- ✨ Add the `CIBW_BEFORE_TEST` option, which lets you run a command to
prepare the environment before your tests are run. (#242)
### 1.2.0
_8 March 2020_
- 🌟 Add support for building PyPy wheels, across Manylinux, macOS, and
Windows. (#185)
- 🌟 Added the ability to build ARM64 (aarch64), ppc64le, and s390x wheels,
using manylinux2014 and Travis CI. (#273)
- ✨ You can now build macOS wheels on Appveyor. (#230)
- 🛠 Changed default macOS minimum target to 10.9, from 10.6. This allows the
use of more modern C++ libraries, among other things. (#156)
- 🛠 Stop building universal binaries on macOS. We now only build x86_64
wheels on macOS. (#220)
- ✨ Allow chaining of commands using `&&` and `||` on Windows inside
CIBW_BEFORE_BUILD and CIBW_TEST_COMMAND. (#293)
- 🛠 Improved error reporting for failed Cython builds due to stale .so files
(#263)
- 🛠 Update CPython from 3.7.5 to 3.7.6 and from 3.8.0 to 3.8.2 on Mac/Windows
- 🛠 Improved error messages when a bad config breaks cibuildwheel's PATH
variable. (#264)
- ⚠️ Removed support for *running* cibuildwheel on Python 2.7. cibuildwheel
will continue to build Python 2.7 wheels for a little while. (#265)
### 1.1.0
_7 December 2019_
- 🌟 Add support for building manylinux2014 wheels. To use, set
`CIBW_MANYLINUX_X86_64_IMAGE` and CIBW_MANYLINUX_I686_IMAGE to
`manylinux2014`.
- ✨ Add support for [Linux on Appveyor](https://www.appveyor.com/blog/2018/03/06/appveyor-for-linux/) (#204, #207)
- ✨ Add `CIBW_REPAIR_WHEEL_COMMAND` env variable, for changing how
`auditwheel` or `delocate` are invoked, or testing an equivalent on
Windows. (#211)
- 📚 Added some travis example configs - these are available in /examples. (#228)
### 1.0.0
_10 November 2019_
- 🌟 Add support for building Python 3.8 wheels! (#180)
- 🌟 Add support for building manylinux2010 wheels. cibuildwheel will now
build using the manylinux2010 images by default. If your project is still
manylinux1 compatible, you should get both manylinux1 and manylinux2010
wheels - you can upload both to PyPI. If you always require manylinux1 wheels, you can
build using the old manylinux1 image using the [manylinux image](https://cibuildwheel.pypa.io/en/stable/options/#linux-image) option.
(#155)
- 📚 Documentation is now on its [own mini-site](https://cibuildwheel.pypa.io),
rather than on the README (#169)
- ✨ Add support for building Windows wheels on Travis CI. (#160)
- 🛠 If you set `CIBW_TEST_COMMAND`, your tests now run in a virtualenv. (#164)
- 🛠 Windows now uses Python as installed by nuget, rather than the versions
installed by the various CI providers. (#180)
- 🛠 Update Python from 2.7.16 to 2.7.17 and 3.7.4 to 3.7.5 on macOS (#171)
- ⚠️ Removed support for Python 3.4 (#168)
### 0.12.0
_29 September 2019_
- ✨ Add CIBW_TEST_EXTRAS option, to allow testing using extra_require
options. For example, set `CIBW_TEST_EXTRAS=test,qt` to make the wheel
installed with `pip install <wheel_file>[test,qt]`
- 🛠 Update Python from 3.7.2 to 3.7.4 on macOS
- 🛠 Update OpenSSL patch to 1.0.2t on macOS
### 0.11.1
_28 May 2019_
- 🐛 Fix missing file in the release tarball, that was causing problems with
Windows builds (#141)
### 0.11.0
_26 May 2019_
- 🌟 Add support for building on Azure pipelines! This lets you build all
Linux, Mac and Windows wheels on one service, so it promises to be the
easiest to set up! Check out the quickstart in the docs, or
[cibuildwheel-azure-example](https://github.com/joerick/cibuildwheel-azure-example)
for an example project. (#126, #132)
- 🛠 Internal change - the end-to-end test projects format was updated, so we
can more precisely assert what should be produced for each one. (#136, #137).
### 0.10.2
_10 March 2019_
- 🛠 Revert temporary fix in macOS, that was working around a bug in pip 19 (#129)

- 🛠 Update Python 3.7.0rc1 to 3.7.0 on macOS (#79)
### 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)
### 0.9.0
_18 June 2018_
- ✨ Add support for Python 3.7 (#73)
### 0.8.0
_4 May 2018_

- 🐛 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!)
