 =================================
 
+ --------
+| v00-15 |  
+ --------

+ 2016-02-10 F.Gaede
+  - added utility  DD4hep::XML::setDetectorTypeFlag()
+    to set the TypeFlag from xml element <type_flag type="0x42"/>
+  - select detectors with 
+    DD4hep::Geometry::DetectorSelector(lcdd).detectors(  ( DD4hep::DetType::TRACKER | DD4hep::DetType::ENDCAP )) ;
+  - used in UtilityApps/dumpdetector.cc
+  - added detector_types.xml with int constants defined in DetType.h, include with :
+    <include ref="${DD4hepINSTALL}/DDDetectors/compact/detector_types.xml"/>
+    - add elements to xml, e.g.
+     <type_flags type="DetType_TRACKER +  DetType_ENDCAP  + DetType_PIXEL + DetType_STRIP "/>

   DDCond
     First implementation of conditions access. Required some movements of files
     from DDG4 (Properties) and some changes in the core conditions implementation.
     The basic infrastructure is now present. Don't know yet however how buggy it is...
 
+2016-02-02 A.Sailer 
+   - add simulator status bit to MCParticles
+
+2016-02-05 F.Gaede
+  - added DetElement::typeFlag() and DetElement::setTypeFlag(unsigned int types)
+  - added utility class DetType for setting detector type properties in type flag

   DDG4
   - Fix the logic for skipping of events at the start of input files: LCIO, HepMC, stdhep and HepEvt
   - Event number in lcio outputfile takes skipped events into account now
