A patch release that restores mise's PATH propagation to subsequent workflow steps — without reintroducing the full-PATH snapshot behavior that v4.2.1 fixed.

Fixed

Export mise PATH entries to subsequent steps (#575) by @jdx

v4.2.1 stopped exporting the complete PATH returned by mise env --json into GITHUB_ENV, which correctly prevented snapshotting the runner's environment into subsequent steps. However, that also dropped mise-produced PATH entries — tool shims, [env] _.path directories, and similar — that workflows relied on after the setup step. See #565.

The action now computes only the prefix that mise prepended to the existing PATH and forwards those directories individually through GITHUB_PATH. This preserves mise's configured ordering, composes cleanly with PATH changes from other actions, and never persists the runner's full PATH through GITHUB_ENV. The dotenv fallback path (used with older mise versions) also strips PATH= lines and re-derives additions from mise env --json.

A new export_path input (default true) lets workflows keep regular env exports while opting out of PATH changes:

- uses: jdx/mise-action@v4
  with:
    export_path: false # keep env vars, skip mise PATH additions
