# Creates a GitHub release when a version tag is pushed. See RELEASING.md.
#
# Publishing to nuget.org stays manual - download the .nupkg from the release
# and upload it at https://www.nuget.org/packages/manage/upload
# That means this workflow needs no secrets: the built-in GITHUB_TOKEN is
# enough to create a release.
