 ### Fixed
 
 - Browser-facing URLs emitted in generated changelog links, workflow summaries, and markdown now use protocol-relative `//` forms.
+- Release workflows now collect summary markdown into portable temp files and print it in explicit `Summary` steps instead of relying on unsupported `GITHUB_STEP_SUMMARY` output.
 - Prepare now recreates the standard `Unreleased` section headers after promoting notes into a tagged release entry.
 - First-release recommendation remains `v1.0.0` when no prior releases exist in the changelog.
 - Do Release smoke validation now expects `--recommend` to fail on tagged release checkouts where `Unreleased` is intentionally empty.
