+   * mdata/MDataPhrase.cc:
+     - updated comments
+     - only add the missing functions to TDataPrimitives when not
+       yet done. Everything lse would leak memory
+
+   * mhbase/MH3.[h,cc], mhvstime/MHVsTime.[h,cc]:
+     - exchanged the MDataChain by MDataPhrase
+     - therefore changed the datamember from MDataChain* to MData*
+       (this change is not necessarily backward compatible)
+     - increased class version number by one
+
+   * mraw/MRawRunHeader.h:
+     - added getter for fObservationMode
+
+   * callisto.cc, ganymed.cc, merpp.cc, readdaq.cc, readraw.cc,
+     showplot.cc, sinope.cc, star.cc, rootlogon.C
+     - enabled error redirection
+
+   * mbase/MLog.[h,cc]:
+     - added code to allow redirection of root error handler to 
+       out own error handler
