@@ -67,7 +67,8 @@ This document describes the differences between v7.0.0 and v6.x.x
 - registerCallBackStartAcquisition gave incorrect imagesize (+120 bytes). corrected.
 - registerCallBackStartAcquisition parameter is a const string reference
 - m3 (runnig config second time with tengiga 0, dr !=32, counters !=0x7) calculated incorrect image size expected
-
+- fixed row column indexing (mainly for multi module Jungfrau 2 interfaces )
+- eiger gui row indices not flipped anymore (fix in config)
