[nsp] 12.2(2) XT3 - IOS branch question

[Michael Axelrod]

Folks,
Does anyone know an easy way to tell if 12.2(2)XT - which was a ED branch of 12.2(2)T - was ever
incorporated back into 12.2T train? 
Docs says that it will be incorporated into 4th 12.2T release and  I can not tell if it  actually happened yet.
