+- 🐛 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)

-- 🌟 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)
