Tag a release

[smyrman]

Would be nice if you are able to tag a release @rs, including the latest fixes, even if there are not to many of them.

Pro-tip: The auto-generated release notes on GitHub are not to bad; it will generate a link to each PR that has been merged since the last release. I notice that there is no GitHub release for v1.3.0, just a v1.3.0 git tag. I think that still works as far as go.mod is concerned, but it would be possible to create a release for that tag first, if you want better auto-generated release notes.
