The 1.3 documents are now available for public comment. By April of 1999, the RTF submitted a revised UML to the OMG, which will be called version 1.4. The RTF expects that the only difference between 1.3 and 1.4 will involve polishing. Unless something very odd happens, the OMG will then adopt 1.4 as the new official standard some time in 1999. At that point, the OMG Analysis and Design Task Force will take over the UML and consider any future moves.
