0.30.5

What's Changed

• Fixed a regression in quoting of pip arguments introduced in
  #185.
  #209

v0.30.4

version 0.30.4 - 2025/05/20

• Fixed compatibility with virtualenv 20.31 and later. The Pyodide virtual environment via pyodide venv no longer seeds
  wheel, i.e., the --wheel/--no-wheel options are not available anymore.
  #208

• The default cross-build metadata URL was changed to https://pyodide.github.io/pyodide/api/pyodide-cross-build-environments.json in order to circumvent rate limits imposed by GitHub. It remains overridable by setting the PYODIDE_CROSS_BUILD_ENV_METADATA_URL environment variable.
  #206

Full range of commits: 0.30.3...0.30.4

v0.30.3

• Added interpreter and package_index to the variables available via pyodide config get.
  #199

v0.30.2

Fixed

v0.30.1

[0.30.1] - 2025/04/25

Added

• pyodide config exposes new variables: pyodide_root, pyodide_abi_version, and python_include_dir,
  and ignored_build_requirements.
  #186 and #187

Fixed

• pyodide venv now works in uv-managed environments.
  See issue #143.
  #185

v0.30.0

version 0.30.0 - 2025/04/08

We are excited to announce the release of pyodide-build v0.30.0.

Full CHANGELOG: pyodide/pyodide-build@a4b038c/CHANGELOG.md

Added

• Added basic support for uv. uv tool install pyodide-cli --with pyodide-build, or
  uvx --from pyodide-cli --with pyodide-build pyodide --help, or using pyodide-build
  in uv-managed virtual environments will now work.
  #132

• pyodide build now takes an additional --xbuildenv-path argument and corresponding
  equivalent PYODIDE_XBUILDENV_PATH environment variable to either use an existing
  cross-build environment or create one at the specified path. This means that users
  can use pyodide xbuildenv install <...> --path to install a cross-build environment
  somewhere and reuse this with pyodide build.
  #158

• Added a new config variable xbuildenv_path that can be left in the [tool.pyodide.build]
  section in pyproject.toml and retrieved through pyodide config get xbuildenv_path.
  The pyodide xbuildenv and pyodide build commands will setup/use cross-build environments
  at this path if one isn't specified as a CLI argument or unless overridden through the
  PYODIDE_XBUILDENV_PATH environment variable.
  #158

• Added support for building without a wheel without build isolation: pyodide build now accepts
  the --no-isolation/-n and/or --skip-dependency-check/-x flags to customise the wheel
  building behaviour, similar to pypa/build.
  #152

Changed

• The Rust toolchain version has been updated to nightly-2025-01-18.
  #103

• Pyodide cross-build environments will now be installed in the user cache directory by default,
  which is <home>/.cache or XDG cache in Linux systems, and /Users/<user>/Library/Caches in macOS.
  #148

• Removed cmake dependency from the package.
  The Pyodide build system now uses the cmake package specified in the pyproject.toml file
  of the target package.
  #141
