+    1.	(Jungfrau)
+	Using multi detector command for powerchip will have a delay of 1 second between
+	modules when there are more than 3 modules for extra protection.

+    2.  Client Callback / Gui (Eiger)
         Client data call back provided the complete image data, but the number of pixels 
         in x and y was provided incorrectly at a modular level. This has been fixed to give 
         the proper value. This also fixes the Gui crashing for Eiger 4 bit mode when 
         acquiring for multiple images.
