# Builds and publishes a release when a version tag is pushed:
#   git tag v0.2.1 && git push origin v0.2.1
# The release gets the four packages (full/launcher x Windows/Linux), SHA256SUMS.txt and the
# matching CHANGELOG.md section as its text. Tests that need the game CD skip themselves here.
#
# Needs: Gitea Actions enabled and a runner with the label "ubuntu-latest" (act_runner).
# The built-in token is used; if it may not create releases on your instance, add a repository
# secret RELEASE_TOKEN (a token with write access to the repository).
