* Two additional features are installed when you upgrade from MOSS 2007 Beta 2 to MOSS Beta 2 Technical Refresh: PublishingB2TRHop2SiteFilesUpgrade & PublishingB2TRSiteFilesUpgrade. These two Features, as their names imply, are used to upgrade some of the publishing files from Beta 2 to Beta 2 Technical Refresh. Because they are upgrade Features, and not likely to be present in the RTM release of MOSS 2007, I am not including them in the count.
