Hurray! The Release Candidate of MemHT 5 has been released!
As it has been announced (very deep in the past), the RC version is the first "real" 5 version, this means it doesn't contain all of the available plugins, languages, templates and extensions. Indeed plugins like Downloads, Files manager, Gallery, Links etc. need to be installed separately (they are almost all available in the SVN revision 157 anyway). Other plugins are not ready yet (Forums, Advertising manager, Newsletter etc), but they will be available soon.
