[dependabot]

Bumps pypa/cibuildwheel from 4.2 to 4.3.

Release notes

Sourced from pypa/cibuildwheel's releases.

v4.3.0

• ✨ 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)
• ✨ Adds GraalPy 3.13 (v25.3) support on Linux, Windows, and macOS arm64, available with the graalpy enable flag (#2982)
• ✨ Adds log-fold-mode to override CI log folding, including CIBW_LOG_FOLD_MODE=disabled to keep build steps expanded (#2972)
• ✨ Adds a python-path input to the GitHub Action to choose the Python interpreter used to run cibuildwheel, and falls back to system python3 on runner architectures unsupported by setup-python, such as native riscv64 (#2990)
• 🐛 Fixes Windows command execution when paths or arguments contain shell metacharacters, including dependency specifiers containing < or > (#2978)
• 🛠 Improves readability of logged commands whose arguments contain quotes (#2993)
• 🛠 Updates Pyodide to 0.27.8, 0.29.5, and 314.0.7, and updates its build tooling, including auditwheel-emscripten 0.3.0 (#2996)
• 🛠 Updates dependencies and container pins, including CPython 3.15.0rc3 (#2986, #3003)
• 📚 Corrects references to --archs in CLI help, error messages, and documentation (#2992)

v4.2.1

• 🐛 Respects the NuGet package sources configured on the machine when installing CPython on Windows, instead of always falling back to nuget.org (#2966)
• 🐛 Fixes a NameError on Pyodide when an already-compatible wheel was reused, which made the test step fail (#2968)
• 🛠 Updates the Android Python versions, and the Android testbed's Gradle version, making it compatible with Java 25 (#2962)
• 🛠 Updates dependencies including CPython 3.15.0rc2 (#2965, #2970, #2976, #2981, #2985)

5 September 2026

• 🐛 Respects the NuGet package sources configured on the machine when installing CPython on Windows, instead of always falling back to nuget.org (#2966)
• 🐛 Fixes a NameError on Pyodide when an already-compatible wheel was reused, which made the test step fail (#2968)

v4.2.0

4 August 2026

• 🌟 CPython 3.15 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 3.15.0rc1, which is guaranteed to be ABI compatible with the final release. (#2944)
• ✨ Adds Pyodide 3.15 support with the cp315-pyodide_wasm32 build identifier, using Pyodide 315.0.0a2. These are also stable wrt. the final release. (#2958)
• 🐛 Retries a failed download six times with exponential backoff, so short network outages no longer stop a build. A 4xx response is still reported at once. (#2953)
• 🐛 Accepts default as a build-frontend value on Pyodide, and accepts pyodide-build in the top-level table and in overrides (#2951)
• 🛠 Holds pip back on GraalPy, where newer pip breaks the build (#2955)
• 🛠 Updates Pyodide to 314.0.4 (#2949, #2952)
• 🛠 Updates dependencies and container pins (#2952, #2960)
• 💼 Updates CI action pins (#2948, #2954)
• 🧪 Uses pp311 for the abi3 test, and deletes test_overridden_pip_constraint, which is not necessary since #2583 (#2956, #2957)

v4.1.1

24 July 2026

• ✨ Adds pyodide-build as a separate build-frontend, now the default frontend for Pyodide, with verbosity flags handling. Any other frontend is ignored with a warning on Pyodide. (#2609, #2945)

Reviewed 7c5d764 against dbca0b1. No actionable regression found in the one-line cibuildwheel 4.2 → 4.3 update.

Checked the complete wheel workflow and pyproject configuration against the upstream action and option-resolution changes. The explicit CIBW_BUILD matrix still selects CPython 3.11 on Linux x86_64, both macOS architectures and Windows, and CPython 3.10 on Linux aarch64; the new interpreter support does not broaden that selection. The action retains setup-python for these X64/ARM64 runners, and the existing macOS x86_64 environment append override remains supported by the updated options cascade.

Validation is incomplete: at review time, all five wheel jobs in run 37766543282 were still building; only the source-distribution job had passed. I did not run builds or tests locally, and this is not a completed wheel/platform validation or merge-readiness approval. Read the Docs reports a separate failure, but its configuration does not use this action and I have no evidence connecting that failure to this bump.
