When publishing a package in GitHub Package Registry, a release and corresponding tag will no longer be created. When publishing a package with a version corresponding to an existing tag and release, the package is automatically associated with that release.
Support for using the GitHub Actions GITHUB_TOKEN to access packages in GitHub Package Registry has also been extended to NuGet packages. You can now publish and consume NuGet packages from Actions by adding GITHUB_TOKEN to your NuGet.config file as a password.
