 ## Releasing
 
-Releases are tag-driven: pushing a `v*.*.*` tag fires [`release.yml`](.github/workflows/release.yml), which builds prebuilt tarballs for `linux-{x86_64,aarch64}` and `macos-{x86_64,aarch64}` and attaches them to a GitHub Release. Beta tags (`v*-beta.*`) are published as pre-releases.

 ### Recommended: cut a release via Actions UI
