No need to reference the version number. 1.4 is implied, because this page will only exist in 1.4+.

If you really want to mention is, best to use future-proof language ("As of 1.4, Riak Enterprise...") so we don't have to keep rewriting this page :)

Same goes for anywhere 1.4 or 1.4.0 is mentioned. Either change the language, or please remove it.
