When I svn checked out the trunk a week or two ago, I got only the trunk. I thought taht was what I want. When I svn updated a couple days ago, it updated the trunk and brought the whole zimbra/branches/EDISON to my zimbra/ work area. Then, I found the announcement posting http://www.zimbra.com/forums/showthread.php?t=3872 regarding EDISION.

Now, I'm confused and have the following questions:
1. What's in the trunk? Stable?
2. What's in EDISON branch?
3. If I'm to create zcs-4.0.1_GA_324.FC4.tgz, do I use trunk or EDISON or other means?
4. In general, what branch system are you using? Always-Branch or Branch-When-Needed as described in: http://svn.collab.net/repos/svn/trun...practices.html
5. Any reasons why the branch is under /trunk/branches and not putting it under /branches/EDISON? I noticed there was a /branches the SourceForge setup already.
