+> [!WARNING]
+> Building and testing wheels executes arbitrary code from your project and its dependencies. Although cibuildwheel uses OCI containers and Pyodide for some builds, these provide no security guarantees - the code you're building and testing has full access to the environment that's invoking cibuildwheel.
+>
+> If you cannot trust all the code that's pulled in, maintain good security hygiene: keep the job that builds distributions separate from the job that uploads them to PyPI, handle secrets and credentials with care and rotate them regularly, and follow the principle of least privilege when granting permissions. Do not store sensitive data on CI runners.

-- 🛠 Update to CPython 3.14.0 final (#2614)
-- 🐛 Fix the default MACOSX_DEPLOYMENT_TARGET on Python 3.14 (#2613)
-- 📚 Docs improvements (#2617)
+- 🌟 Adds wheel auditing with `abi3audit` as a default after the repair step, with new [`audit-requires`](https://cibuildwheel.pypa.io/en/stable/options/#audit-requires) and [`audit-command`](https://cibuildwheel.pypa.io/en/stable/options/#audit-command) options (#2805)
+- 🌟 Adds `pyemscripten` platform tag support (PEP 783), updates Pyodide to 314.0.0a1, and adds a `pyodide-eol` [`enable`](https://cibuildwheel.pypa.io/en/stable/options/#enable) flag for building end-of-life Pyodide versions (#2812, #2848)
+- 🌟 Sets up `delvewheel` as the default [`repair-wheel-command`](https://cibuildwheel.pypa.io/en/stable/options/#repair-wheel-command) for Windows, so extension module DLLs are now bundled automatically. Skip by setting it to empty if not needed. (#2831)
+- ✨ Adds CPython 3.15 support, under the [`enable` option](https://cibuildwheel.pypa.io/en/stable/options/#enable) `cpython-prerelease`. This version of cibuildwheel uses 3.15.0b1. (#2833, #2850)
 
-### v3.2.0
-
-_22 September 2025_
-
-- ✨ 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)
-- 📚 Docs improvements (#2574, #2601, #2598)
-
-### v3.1.4
-
-_19 August 2025_
-
-- ✨ Add a `--clean-cache` command to clean up our cache (#2489)
-- 🛠 Update Python to 3.14rc2 and other patch version bumps (#2542, #2556)
-- 🛠 Update Pyodide to 0.28.2 (#2562, #2558)
-- 🐛 Fix resolution with `pyodide-build` when `dependency-versions` is set (#2548)
-- 🐛 Set `CMAKE_FIND_ROOT_PATH_MODE_PACKAGE` to `BOTH` on Android (#2547)
-- 🐛 Add `patchelf` dependency for platforms that can build Android wheels (#2552)
-- 🐛 Ignore empty values for `CIBW_ARCHS` like most other environment variables (#2541)
-- 💼 The `color` and `suggest_on_error` argparse options are now default in 3.14rc1+ (#2554)
-- 💼 Use the virtualenv release URL instead of blob URL (should be more robust) (#2555)
-- 🧪 For iOS, lowering to macos-14 is needed for now due to issues with GitHub's runner images (#2557)
-- 🧪 Split out platforms iOS and Android in our tests (#2519)
-- 🧪 Fix and enable doctests (#2546)
-- 📚 Improve our docs on free-threading (#2549)
+    _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 `{project}` and `{package}` placeholders to [`config-settings`](https://cibuildwheel.pypa.io/en/stable/options/#config-settings) (#2827)
+- ⚠️ Drops support for Python 3.8 (#2686)
+- ⚠️ Removes the experimental CPython 3.13 free-threading builds and the `cpython-freethreading` [`enable`](https://cibuildwheel.pypa.io/en/stable/options/#enable) option. CPython 3.14+ free-threading support remains available without the enable flag. (#2684)
+- ⚠️ Drops support for Cirrus CI, which is shutting down June 1, 2026 (#2817)
+- 🐛 Fixes `UV_PYTHON` not being set for [`before-build`](https://cibuildwheel.pypa.io/en/stable/options/#before-build) on Linux when using `uv` as the [`build-frontend`](https://cibuildwheel.pypa.io/en/stable/options/#build-frontend) (#2830)
+- 🛠 Updates Android to Python 3.13.13 and 3.14.4 (#2821)
+- 🛠 Applies Pyodide-specific patches to the Emscripten toolchain installation (#2800)
+- 🛠 Updates dependencies and container pins (#2845, #2837, #2821, #2818, #2810, #2838, #2813)
+- 🛠 Uses `python -V -V` for Windows build diagnostics (#2832)
+- 📚 Documents platform-specific [`before-build`](https://cibuildwheel.pypa.io/en/stable/options/#before-build) configuration (#2834)
+- 📚 Updates the "How it works" diagram with details of Android, iOS, and Pyodide builds (#2816)
+- 📚 Adds Pyodide icon and regenerates working examples data for Android, iOS, and Pyodide (#2815, #2811)
+- 📚 Links back to source in docs (#2806)
+- 💼 Adds PEP 723 metadata for `bin/` scripts and drops the `bin` dependency group (#2819)
+- 💼 Updates CI action pins and dev dependencies (#2851, #2843, #2826, #2823, #2820, #2807)
+- 🧪 Fixes Android tests using the `uv` frontend (#2809)
+- 🧪 Fixes the update-dependencies workflow to use `uv` to run `nox` (#2808)

-- 🐛 Fix bug where "latest" dependencies couldn't update to pip 25.2 on Windows (#2537)
-- 🧪 Use pytest-rerunfailures to improve some of our iOS/Android tests (#2527, #2539)
-- 🧪 Remove some GraalPy Windows workarounds in our tests (#2501)
+- ⚠️ Building for the experimental CPython 3.13 free-threading variant is now deprecated. That functionality will be removed in the next minor release. The [`enable`](https://cibuildwheel.pypa.io/en/stable/options/#enable) option `cpython-freethreading` is therefore also deprecated. Builds specifying `enable = "all"` no longer select `cpython-freethreading`. CPython 3.14 free-threading support remains available without the `enable` flag. (#2787)
+- 🐛 iOS builds will no longer skip `repair-wheel-command` if it's defined in config (#2761)
+- 🐛 Fix bug causing `uv` to fail when environments define PYTHON_VERSION or UV_PYTHON, conflicting with our venvs (#2795)
+- ✨ cibuildwheel prints the selected build identifiers at the start of the build. (#2785)
+- 🔐 The GitHub Action now references other actions with a full SHA (#2744)
 
+### v3.4.0
 
-### v3.1.2
+_5 March 2026_
 
-_29 July 2025_
+- 🌟 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)
+- 🛠 Update Pyodide to 0.29.3 (#2719, #2733)
+- 🐛 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)
 
-- ⚠️  Add an error if `CIBW_FREE_THREADING_SUPPORT` is set; you are likely missing 3.13t wheels, please use the `enable`/`CIBW_ENABLE` (#2520)
-- 🛠 `riscv64` now enabled if you target that architecture, it's now supported on PyPI (#2509)
-- 🛠 Add warning when using `cpython-experimental-riscv64` (no longer needed) (#2526, #2528)
-- 🛠 iOS versions bumped, fixing issues with 3.14 (now RC 1) (#2530)
-- 🐛 Fix bug in Android running wheel from our GitHub Action (#2517)
-- 🐛 Fix warning when using `test-skip` of `"*-macosx_universal2:arm64"` (#2522)
-- 🐛 Fix incorrect number of wheels reported in logs, again (#2517)
-- 📚 We welcome our Android platform maintainer (#2516)

+_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)
+- 🛠 Improve the handling of `test-command` on Android, enabling more options to be passed (#2590)
+- 📚 Docs improvements (#2618)

+# Maintaining Pyodide support
+
+Last updated: May 2026
+
+This page describes how to update cibuildwheel's Pyodide platform code when either:
+
+- a new Pyodide alpha release arrives with support for a new [PyEmscripten Platform](https://pyodide.org/en/latest/development/abi.html) (which is tied to updates in Emscripten and CPython versions, compiler/linker flags, and so on), or
+- when that alpha release graduates to a stable one.
+
+## Background
+
+Pyodide has three types of releases that matter to cibuildwheel:
+
+- **Stable** – the most recent full Pyodide release (e.g., `0.29.x` / cp313). This is enabled by default with no special `CIBW_ENABLE` flag needed.
+- **Prerelease** – an alpha/beta/rc Pyodide release that uses the _next_ CPython version (e.g., `314.0.0a1` / cp314). Users must opt in with `CIBW_ENABLE: pyodide-prerelease` to build against this version. This may or may not be available at any given time, depending on the Pyodide release cycle.
+- **End-of-life (EoL)** – older Pyodide stable releases that are no longer the current stable. These are kept available behind `CIBW_ENABLE: pyodide-eol` so that users who still need to build for older Pyodide versions can do so.
+
+The guards in `cibuildwheel/selector.py` enforce this distinction. The constraints files under `cibuildwheel/resources/` pin the exact tool versions that go with each build.
+
+---
+
+## When a new Pyodide prerelease becomes available
+
+For example, consider a scenario when Pyodide ships a new `315.0.0a1` with cp315 support.
+
+### 1. Add the new Python configuration
+
+In `cibuildwheel/resources/build-platforms.toml`, add an entry under `[pyodide]`:
+
+```toml
+{ identifier = "cp315-pyodide_wasm32", version = "3.15", default_pyodide_version = "315.0.0a1", node_version = "v24" },
+```
+
+`version` is the CPython version string, `default_pyodide_version` is the Pyodide release to use when the user does not pin one explicitly (use the latest available alpha/beta for a prerelease entry), and `node_version` is the minimum Node.js major required by that Pyodide release — check the [pyodide-build FAQ](https://pyodide-build.readthedocs.io/en/latest/faq.html#what-node-js-version-do-i-need) for a rudimentary idea of what the correct value is.
+
+### 2. Update the prerelease guards in the selector
+
+In `cibuildwheel/selector.py`, update the patterns in the `PyodidePrerelease` guards to match the new identifier:
+
+```python
+if EnableGroup.PyodidePrerelease not in self.enable and fnmatch(
+    build_id, "cp315-pyodide_*"
+):
+    return False
+```
+
+### 3. Generate and pin a constraints file
+
+Run the `update_constraints` `nox` session, which reads `build-platforms.toml` and regenerates all Pyodide constraints files automatically:
+
+```bash
+nox -s update_constraints
+```
+
+### 4. Update tests
+
+Update the unit tests so the new identifier is accepted by the selector with `PyodidePrerelease` enabled and rejected without it. Pyodide-specific integration tests may also need their hardcoded expected-wheel lists extended.
+
+## When a Pyodide prerelease becomes stable
+
+Pyodide uses a versioning scheme where the stable release for a given CPython version is named `[PythonMajorMinor].0.0`, so the first stable release shipping cp314 will be **`314.0.0`**. See [pyodide/pyodide#6084](https://github.com/pyodide/pyodide/issues/6084) for a rationale of this versioning scheme.
+
+### 1. Update the stable entries, and remove (or replace) the prerelease entry
+
+In `build-platforms.toml`, update the former prerelease entry's `default_pyodide_version` to the new stable release (e.g. `314.0.0`) and remove the prerelease marker from the identifier if present. Remove previous prerelease entries if they are now obsolete, or update them to the next prerelease if one is available. Move the previous stable version behind `pyodide-eol` rather than dropping it outright (see below).
+
+### 2. Disable or update the prerelease guards
+
+In `selector.py`:
+
+- **If a new prerelease is available**: update the `fnmatch` pattern to the next identifier (e.g. `cp315-pyodide_*`) as described above.
+- **If there is no new prerelease**: comment out the `PyodidePrerelease` logic.
+
+### 3. Update the constraints file
+
+Run `nox -s update_constraints` to regenerate the constraints file for the newly stable version. If the entry was already in `build-platforms.toml` as a prerelease, its constraints file already exists, and this step just refreshes it against the stable Pyodide release and updates the dependencies' versions.
+
+### 4. Update tests
+
+Update the unit tests so the newly stable identifier is accepted by the selector without needing `PyodidePrerelease` in the enable set. Pyodide-specific integration tests may also need their hardcoded expected-wheel lists extended.
+
+## When an old Pyodide version is to be moved to end-of-life
+
+When a Pyodide version is superseded by a new stable release, move it behind the `pyodide-eol` enable flag. We want to allow users who still build for older Pyodide ABIs time to upgrade.
+
+### 1. Add the `pyodide-eol` guard in the selector
+
+In `cibuildwheel/selector.py`, add (or update) the `PyodideEoL` guard to include the old identifier:
+
+```python
+if EnableGroup.PyodideEoL not in self.enable and fnmatch(build_id, "cp312-pyodide_*"):
+    return False
+```
+
+### 2. Update tests
+
+Update the unit tests so the EoL identifier requires `PyodideEoL` to be included in the enable set. The default (no `CIBW_ENABLE`) should exclude it.
+
+## When an old Pyodide version is to be fully retired
+
+Retirement is not expected to happen on a routine basis. It is only warranted when the Pyodide ecosystem itself has evolved to the point where an older ABI version is considered obsolete – for example, if the surrounding toolchain, packaging standards, or runtime infrastructure have moved on so substantially that building for the older version no longer makes practical sense. Any retirement is to be discussed and agreed upon by Pyodide maintainers before proceeding.
+
+### 1. Remove the Python configuration
+
+Delete the entry from `build-platforms.toml` and remove the `PyodideEoL` guard for that identifier in `selector.py`.
+
+### 2. Delete the constraints file
+
+Remove `cibuildwheel/resources/constraints-pyodideXYZ.txt`.
+
+### 3. Update tests
+
+Remove references to the old identifier from the unit tests, integration tests, and drop any expected-wheel entries for it from the test helper.

 # Changelog
 
+### v4.0.0rc1
+
+_14 May 2026_

+- 🌟 Adds wheel auditing with `abi3audit` as a default after the repair step, with new [`audit-requires`](https://cibuildwheel.pypa.io/en/stable/options/#audit-requires) and [`audit-command`](https://cibuildwheel.pypa.io/en/stable/options/#audit-command) options (#2805)
+- 🌟 Adds `pyemscripten` platform tag support (PEP 783), updates Pyodide to 314.0.0a1, and adds a `pyodide-eol` [`enable`](https://cibuildwheel.pypa.io/en/stable/options/#enable) flag for building end-of-life Pyodide versions (#2812, #2848)
+- 🌟 Sets up `delvewheel` as the default [`repair-wheel-command`](https://cibuildwheel.pypa.io/en/stable/options/#repair-wheel-command) for Windows, so extension module DLLs are now bundled automatically. Skip by setting it to empty if not needed. (#2831)
+- ✨ Adds CPython 3.15 support, under the [`enable` option](https://cibuildwheel.pypa.io/en/stable/options/#enable) `cpython-prerelease`. This version of cibuildwheel uses 3.15.0b1. (#2833, #2850)
+
+    _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 `{project}` and `{package}` placeholders to [`config-settings`](https://cibuildwheel.pypa.io/en/stable/options/#config-settings) (#2827)
+- ⚠️ Drops support for Python 3.8 (#2686)
+- ⚠️ Removes the experimental CPython 3.13 free-threading builds and the `cpython-freethreading` [`enable`](https://cibuildwheel.pypa.io/en/stable/options/#enable) option. CPython 3.14+ free-threading support remains available without the enable flag. (#2684)
+- ⚠️ Drops support for Cirrus CI, which is shutting down June 1, 2026 (#2817)
+- 🐛 Fixes `UV_PYTHON` not being set for [`before-build`](https://cibuildwheel.pypa.io/en/stable/options/#before-build) on Linux when using `uv` as the [`build-frontend`](https://cibuildwheel.pypa.io/en/stable/options/#build-frontend) (#2830)
+- 🛠 Updates Android to Python 3.13.13 and 3.14.4 (#2821)
+- 🛠 Applies Pyodide-specific patches to the Emscripten toolchain installation (#2800)
+- 🛠 Updates dependencies and container pins (#2845, #2837, #2821, #2818, #2810, #2838, #2813)
+- 🛠 Uses `python -V -V` for Windows build diagnostics (#2832)
+- 📚 Documents platform-specific [`before-build`](https://cibuildwheel.pypa.io/en/stable/options/#before-build) configuration (#2834)
+- 📚 Updates the "How it works" diagram with details of Android, iOS, and Pyodide builds (#2816)
+- 📚 Adds Pyodide icon and regenerates working examples data for Android, iOS, and Pyodide (#2815, #2811)
+- 📚 Links back to source in docs (#2806)
+- 💼 Adds PEP 723 metadata for `bin/` scripts and drops the `bin` dependency group (#2819)
+- 💼 Updates CI action pins and dev dependencies (#2851, #2843, #2826, #2823, #2820, #2807)
+- 🧪 Fixes Android tests using the `uv` frontend (#2809)
+- 🧪 Fixes the update-dependencies workflow to use `uv` to run `nox` (#2808)
+
+
+### v3.4.1
+
+_2 April 2026_
+
+- ⚠️ Building for the experimental CPython 3.13 free-threading variant is now deprecated. That functionality will be removed in the next minor release. The [`enable`](https://cibuildwheel.pypa.io/en/stable/options/#enable) option `cpython-freethreading` is therefore also deprecated. Builds specifying `enable = "all"` no longer select `cpython-freethreading`. CPython 3.14 free-threading support remains available without the `enable` flag. (#2787)
+- 🐛 iOS builds will no longer skip `repair-wheel-command` if it's defined in config (#2761)
+- 🐛 Fix bug causing `uv` to fail when environments define PYTHON_VERSION or UV_PYTHON, conflicting with our venvs (#2795)
+- ✨ cibuildwheel prints the selected build identifiers at the start of the build. (#2785)
+- 🔐 The GitHub Action now references other actions with a full SHA (#2744)
+
+### 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)
+- 🛠 Update Pyodide to 0.29.3 (#2719, #2733)
+- 🐛 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)
+- 🛠 Improve the handling of `test-command` on Android, enabling more options to be passed (#2590)
