IP.Suite 4.0 was announced in this blog entry on May 23, 2012. Version 4.0 is a complete ground-up rewrite of Invision Power Board and the collection of applications that Invision Power Services sell. 4.0 contains a large number of new features that have been suggested by users and aims to completely overhaul how IP.Suite functions on both the user-side and administrator-side. It was originally to be released in 2014 but was pushed back a number of times as it went through several pre-release and beta versions.
