Support Immutable Releases

[EelcoLos]

Describe

As immutable releases are now generally available (https://github.blog/changelog/2025-10-28-immutable-releases-are-now-generally-available/) can you enable this on the repository?

Proposed solution

enable the setting on the repository. according to github, this should be the only thing you should set

Alternatives considered

don't enable this

Hi @EelcoLos, thanks for this suggestion.

I am not sure how immutable releases would work with the tag which must be changed with each release (eg. v2 tag).

I would also wait how this will be implemented in the actions/* repositories, eg. actions/checkout#2316

Immutable releases must be enabled by a repo admin, in this case @dorny.
