Recently I’ve asked Where is SysML 1.4? Due to some formal problems it took a long time to make an official publication of the new version SysML 1.4. The work on the SysML 1.4 was completed a long time ago.
Now SysML 1.4 is officially published. You find the specification on the OMG server: http://www.omg.org/spec/SysML/1.4/ .
I’ve written a blogpost series about the changes of SysML 1.4.
