Version	v12r1
Release Date	21 September 2004
WARNING	This version is based on the new CMT version (more details are here). Your working directory ($CMTPATH) is now $HOME/cmtuser in order to avoid conflicts with the old CMT.
Description	Warning: BUGGY ParticleFilter!   Development version. Based on Gaudi v15r2 and LHCb v16r2. Includes LoKi v3r4p2.   Development version including new features in the trigger and the HLT.   This version also includes the new Stripping tools to be used for stripping tests.
Main modifications	Main modifications with respect to v12r0: New Gaudi and LHCb, including a bug-fix of PoolDBV allowing to merge event-tag-collections. Changes in Calo software: CaloDigitsFromRaw uses the new algorithm-on-demand fetaure of Gaudi. CaloDigits will thus only be redone when necessary. New Trg event model and changes in L1. New features in HLT. All DaVinci tools now run on particles made from trigger tracks for HLT.    User selections can be adapted easily too:    1) if you use the PV from VertexLocation::Primary, foresee the       possibility to get it from TrgVertexLocation::Velo3D in HLT mode    2) Check always that the protoparticle is actually there         ProtoParticle* PP = dynamic_cast<ProtoParticle*>((*iPart)->origin());       might be NULL. In this case you can do         TrgTrack* TT = dynamic_cast<TrgTrack*>((*iPart)->origin());       You will need to #include "Event/TrgTrack.h" for this.    3) Replace DaVinciReco.opts by Hlt.opts and do not run any particle maker.       You can decide if you want to make all particles both as pions and       kaons (default), or only as kaons with         TrgParticleMaker.MakeKaon = false ;       Your particles will be in /Event/Phys/Trg LoKi v3r4p2.
Known problems:	L0Muon crashes when used with Hbook output
	Bug in ParticleFilter: A bug has been found in ParticleFilter. Filter criteria are ignored starting from the second of the "AndList". If you use ParticleFilter take the head revision of the Phys/DaVinciFilter package > getpack Phys/DaVinciFilter head
	GaudiPython cannot be used with POOL persistency. Use ROOT data instead.
