What do you mean? Changelog, manual, etc.? The changelog is available here: http://www.howtoforge.com/forums/showthread.php?t=2823 The manual is available here: http://www.ispconfig.org/documentation.htm
No, not at all. I mean a documatation or a status of the developer version which I found here: http://www.ispconfig.org/downloads/ISPConfig-svn-current.tar.gz tom
You can get the status of the developer version with an SVN client. Just connect to the SVN repository listed on the downloads page and you get the realtime changelog of the dev version. By the way, a nice SVN client for windows is tortoisesvn.
