Version	v9r4 - branch
Release Date	9 April 2004
Description	DaVinci v9r4 is an updated version fully compatible with TDR data. It is identical with DaVinci v9r3 except for some geometry-independent improvements introduced in versions v10 to v11r5. In particular there are several bug fixes in the DaVinci(MC)Tools and a new version of the B Tagging. Also some new decay selections are introduced or updated.   Note that this is a branch, hence no developments based on this version are supported. Please base your changes on DaVinci v11r5 or later.   Apart from geometry changes, some backward-incompatible modifications in DaVinci v11 are not in this version. In particular DV v9r4 does not contain the new DVAlgorithm.h, hence selection following the guidelines will not run with DaVinci v9r4. Also the new track naming scheme is not applied.   People who would like to run the same algorithm with DaVinci v9r4 and DaVinci v11rX are encouraged to use precompiler flags in their requirement file macro_append     cppflags " -DDVvnine " \                  VisualC  " /DDVvnine " and #ifdef DVvnine [...] #endif in their source code. Please leave the flags commented out in the requirements file you put in CVS.   All DaVinci v9r3 features
