PMP450x Release 15.1.1 is now available

Problem: again the problem of High Priority Channel .

Installed the stable 15.1.1 in AP only. When customers saturated download, the voice it's fragmented.
In AP, Statistics, Data VC, COS 01 it's populated but not prioritized.

This is a "old" bug in 14.2.X until 15.0. This problem had been resolved in 15.1:

450/450i/450m CPY-13103 Fix for High Priority traffic throughput dropping when offered load is higher than MIR.

I see that problem was also with 15.1.1 Beta 5. It's  very important fix it!

EDIT: 
it's possible that problem never fix it in AP Medusa? i tested now only customers with medusa
