Changed to 7.3.1 because 7.3.0 will not be released.

I had to change the version number to 7.3.1 because I can't untag and then retag the latest master (at least I don't think so). So the release will be named 7.3.1. Not certain we are releasing as is. There may be one more code change.

It's possible to change tags on remote but not recommended.

If you want to create draft releases for test purpose, you can just do tags like v1.2.3-alpha1 or whatever respects server.org
This way you don't have to change release notes. Once ready redo a tag v1.2.3 on same commit and publish actual release. There will be 2 tags on same place (plus all the alphas123/betas...) but that's something usual
