 - 🌟 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)
