      - added a dynamic_cast from MParContainer to MCamEvent to get the
        correct pointer to the correct base-class.
+
+   * mbase/MStatusDisplay.cc:
+     - In EventInfo check whether gPad==0
+     
+   * mfileio/MReadMarsFile.cc:
+     - removed reading RunHeaders from PreProcess, this resulted
+       in strange behaviour of writing RunHeaders
+     - fixed consistency check for RunType accordingly
+
+   * mfilter/MFilterList.cc:
+     - do not skip adding filter if only a filter with the same name 
+       exists
+       
+   * mraw/MRawFileRead.cc:
+     - added an output message if run header is not accessible
+     
+   * mraw/MRawRunHeader.[h,cc]:
+     - initialize fRunType to new enum kRTNone
