There are so many sites out there keeping track of SharePoint builds. Many seem to stop at some point (they lose interest I guess) and end up out of date. I prefer to use what appears to me to be the most comprehensive lists as they are from the horse’s mouth (Microsoft Technet site) and also provide lots of background as well. So here they are, to bookmark.

Steve Chen has a very nice list as well and seems to be one of the few keeping on top of it.
