How will the skins stand up from RC1? I noticed to upgrade you need to upload the templates so does that mean there are a lot of changes there? I haven't tried and I don't want to mess up anything new that may have been fixed...so I just want to know if I need to update my skins...
There was a change in the compose mail file and address book files, small changes but still changes but still worth the upgrade. Also support for the html editor was added.
