name: Release

# Publishes a GitHub Release for every new version in Cargo.toml: once CI
# passes on a main commit whose `v<version>` has no release yet, this builds
# the Linux and Windows archives, tags that commit, and attaches the archives
# with the version's CHANGELOG.md entry as the notes. Run it by hand
# ("Run workflow") to retry a failed publish.

# Keep shaderc-sys source builds working on runners that provide CMake 4.
