Trying to figure cisco's new release and why they jumped from 12.X code to 15.X code. What happened to 13 and 14 . :-) I see this out there for the 2800 series now . It's a ED release. It looks like they made 15.X the mainline code for the 12.4T train , wonder why they skipped 13.0 or 14 ? Sounds like they are taking it down to 2 trains either maintenance or T trains , about time they simplified it !!!
