Changelog

v4.3.5

27 October 2026

• 🐛 Stops passing the target build environment to the host virtualenv call, regression in v4.3.4 (#3023)

• 💼 Updates CI actions (#3025)

v4.3.4

22 October 2026

• 🔐 Warns when a uv build frontend is selected and the host uv is older than 0.13.4, which still trusts the compromised eMudhra CA roots (#3021)
• 🔐 Uses cibuildwheel's CA bundle for pip on Python 3.9, where pip uses its bundled certifi, which still trusts the compromised eMudhra roots (#3017)
• 🔐 Uses cibuildwheel's CA bundle for pip on GraalPy, where truststore is not supported (#3019)
• 🔐 Uses cibuildwheel's CA bundle in Android, iOS, and Pyodide cross venvs, where pip uses the host's OpenSSL CA file (#3020)
• 🐛 Seeds build's isolated environment with the pinned pip on macOS and Windows, fixing GraalPy 25.0 builds (#3018)
• 💼 Stops Azure cache growth from restoreKeys (#3022)

v4.3.3

21 October 2026

• 🔐 Updates manylinux images and pip to fix vulnerability to eMudhra.

v4.3.2

20 October 2026

• 🔐 Updates our dependency pins to certifi==2026.10.19, following the eMudhra Intermediate CA Compromise. Linux builds may still be vulnerable through manylinux images - a patch release will soon follow if so.

v4.3.1

10 October 2026

• 🛠 Updates CPython 3.15 to the final 3.15.0 release (#3009)

v4.3.0

5 October 2026

• ✨ Extends option inheritance to every configuration layer, so global and platform-specific settings can append or prepend to existing values, including cibuildwheel's defaults. Environment variables can also extend earlier settings using CIBW_INHERIT. (#2928)
• ✨ Adds PyPy 3.12 support and updates PyPy 3.11 to v8.0.0, available with the pypy enable flag (#2998)

Updates astral-sh/setup-uv from 10.3.2 to 10.3.3

Release notes

Sourced from astral-sh/setup-uv's releases.

v10.3.3 🌈 Use Astral mirror for version manifests with GitHub fallback

Changes

This release contains something that should have been included a very long time ago. Sorry for sleeping on that.

This action now retrieves the release manifest that contains the available versions, their download links and checksums from the Astral mirror, rather than trying GitHub first. This should present much more stable. (Known checksums are still checked, so the security impact does not change)

Also a big thank you to @​soujasK for a set of bugfixes 👏

Looks like these dependencies are updatable in another way, so this is no longer needed.
