And I also found a way to generate most of the message above automatically.
git log --pretty=format:'[*][bugfix] %C(yellow)%d%Creset %s ([url=https://github.com/elkarte/Elkarte/commit/%h]ref[/url]).' --abbrev-commit
Now I have only to discover two other things:
1) limit the commits only to those from the branching
2) list them inverted
