When making a release from a milestone, I entered a description, but when it was created, it actually had the description of the milestone shoved before it. I imagine this is not an accident and could be cool in theory, except that a) it shows up first and b) I can't choose to disable it. If anything you should be able to preface the milestone information with a brief release overview, and not have to put that afterwards. Also I tend to keep my milestones more technical and do the overview from that perspective, so I really don't want that showing up at all on the release page.
Thirdly, when the milestone description gets put into the release, it removes all the newlines which just collapses it all into one giant header paragraph. See https://edge.launchpad.net/wxbanker/+milestone/0.5 versus https://edge.launchpad.net/wxbanker/0.5/0.5 .
Overall I like the direction of making releases publishable from milestones and think the integration has excellent potential, but right now it is making way too many assumptions and on top of that making them IMHO poorly and with errors.
I temporarily removed the milestone description as I want to announce the release and don't want the milestone description there, so I suppose those links above won't be relevant anymore, except perhaps on staging for a bit longer.
