-- 🌟 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)

+- ⚠️ 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).

+_1 March 2025_
 
-- 🌟 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)
+- ✨ 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)

-- 🌟 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)
+- 🌟 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)

 # Changelog
 
+### v2.23.3
+
+_26 April 2025_
+
+- 🛠 Dependency updates, including Python 3.13.3 (#2371)
+
+### v2.23.2
+
+_24 March 2025_
+
+- 🐛 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)
+
+### v2.23.1
+
+_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)
+
+### v2.23.0
+
+_1 March 2025_
+
+- ✨ 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)
+
+### 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)
+- 🛠 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)
+
+
+### v2.21.3
+
+_9 October 2024_
+
+- 🛠 Update CPython 3.13 to 3.13.0 final release (#2032)
+- 📚 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)

 ### 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)

To find out if this is the case, try compiling and running with a lower `MACOSX_DEPLOYMENT_TARGET`: if C++17 features are used that require a more recent deployment target, building the wheel should fail.

 Linux wheels are built in [`manylinux`/`musllinux` containers](https://github.com/pypa/manylinux) to provide binary compatible wheels on Linux, according to [PEP 600](https://www.python.org/dev/peps/pep-0600/) / [PEP 656](https://www.python.org/dev/peps/pep-0656/). Because of this, when building with `cibuildwheel` on Linux, a few things should be taken into account:
 
--   Programs and libraries are not installed on the CI runner host, but rather should be installed inside the container - using `yum` for `manylinux2010` or `manylinux2014`, `apt-get` for `manylinux_2_24`, `dnf` for `manylinux_2_28` and `apk` for `musllinux_1_1` or `musllinux_1_2`, or manually. The same goes for environment variables that are potentially needed to customize the wheel building.

 The list of supported and currently selected build identifiers can also be retrieved by passing the `--print-build-identifiers` flag to cibuildwheel.
 The format is `python_tag-platform_tag`, with tags similar to those in [PEP 425](https://www.python.org/dev/peps/pep-0425/#details).
 
-For CPython, the minimally supported macOS version is 10.9; for PyPy 3.7, macOS 10.13 or higher is required.
+The lowest value you can set `MACOSX_DEPLOYMENT_TARGET` is as follows:
+
+| Arch  | Python version range | Minimum target |
+|-------|----------------------|----------------|
+| Intel | CPython 3.6-3.11     | 10.9           |
+| Intel | CPython 3.12+        | 10.13          |

+| Intel | PyPy 3.7-3.8         | 10.13          |
+| Intel | PyPy 3.9+            | 10.15          |
+
+If you set the value lower, cibuildwheel will cap it to the lowest supported value for each target as needed.

-### `CIBW_FREE_THREADED_SUPPORT` {: #free-threaded-support}
-
-> Choose whether free-threaded variants should be built
-
-[PEP 703](https://www.python.org/dev/peps/pep-0703) introduced variants of CPython that can be built without the Global Interpreter Lock (GIL).
-Those variants are also known as free-threaded / no-gil.
-
-Building for free-threaded variants is disabled by default.
-
-Building can be enabled by setting this option to `true`. The free-threaded compatible wheels will be built in addition to the standard wheels.
-
-This option doesn't support overrides.
-If you need to enable/disable it per platform or python version, set this option to `true` and use [`CIBW_BUILD`](#build-skip)/[`CIBW_SKIP`](#build-skip) options to filter the builds.
-
-The build identifiers for those variants have a `t` suffix in their `python_tag` (e.g. `cp313t-manylinux_x86_64`)
-
-!!! note
-    This feature is experimental: [What’s New In Python 3.13](https://docs.python.org/3.13/whatsnew/3.13.html#free-threaded-cpython)

-    CIBW_FREE_THREADED_SUPPORT: 1
-    CIBW_SKIP: *t-win*

+This option lets you opt-in to non-default builds, like pre-releases and

+  (May-July, approximately). For backward compatibility, `CIBW_PRERELEASE_PYTHONS`
+  is also supported until cibuildwheel 3.
+- `cpython-freethreading`: [PEP 703](https://www.python.org/dev/peps/pep-0703)
+  introduced variants of CPython that can be built without the Global
+  Interpreter Lock (GIL).  Those variants are also known as free-threaded /
+  no-gil. This will enable building these wheels while they are experimental.
+  The build identifiers for those variants have a `t` suffix in their

+  cibuildwheel 3 is released.
 
-During the beta period, when new versions of Python are being tested,
-cibuildwheel will often gain early support for beta releases. If you would
-like to test wheel building with these versions, you can enable this flag.
 
 !!! caution
-    This option is provided for testing purposes only. It is not
-    recommended to distribute wheels built when `CIBW_PRERELEASE_PYTHONS` is
-    set, such as uploading to PyPI.  Please _do not_ upload these wheels to
-    PyPI, as they are not guaranteed to work with the final Python release.
