IMMUTABLE RELEASES ARE NOW GENERALLY AVAILABLE

Summary from the TLDR newsletter

GitHub releases now support immutability. Immutable releases protect assets and tags from being tampered with after publication. This ensures that the software remains secure and trustworthy. Immutable releases can be enabled at the repository or organizational level. Once enabled, all new releases will be immutable - existing releases remain mutable unless they are republished. Disabling immutability doesn't affect releases created while it was enabled.
