Version	v11r9
Release Date	29 Jun 2004
Description	Version for DC'04 production tests. Based on Gaudi v14r6 and LHCb v15r12. Includes LoKi v2r6. Is used by Bender v3r3.   Many new features: The Phys/DaVinciAssociators have been updated. The old way still works, but the new version is faster and easier to use. The DaVinciAssociators User Guide will be updated soon. Have a look at the slides from Software week or at the release notes. The efficiency algorithm in Phys/DaVinciEff has been rewritten. It allows to calculate the reconstruction efficiency for any decay. Have a look at he slides from Software week. A note is expected soon. There are example option files in the DaVinciEff/v3r0/options folder. CombineParticles (in Phys/PhysSelections): a new algorithm that allows to reconstruct any decay using only job options. Look at example option files in the Bs2JpsiPhi and Bu2LLK packages. PVIPFilterCriterion (in Phys/DaVinciTools) allows to filter particles according to their IP (or IP significance) to the reconstructed PVs. Works also for the pointing requirement for the B. ParticleMakerSeq (in Phys/DaVinciTools): A sequencer of particle makers. Allows to avoid PreLoadParticles. DumpEvent (in Phys/DaVinciMCTools): Dumps the event using the debug tool. EventNumber (in Tools/Utilities): A tool that returns the number of events processed (waiting for Gaudi to provide it...). PostScaler (in Tools/Utilities): The algorithm that is going to be executed at the end of each preselection sequencer. Forces the output rate to be 1/1000. Tools/Stripping: The new package that manages the stripping. The Trigger has been completely upgraded. With Gaudi v15r6 comes the new GaudiSequencer, with an OR mode and many more goodies. This version compiles on Windows. Please use it and report any problems.
Main modifications	Only additions, as DaVinci has to be backward-compatible until DC'04 stripping.
Known problems:	B2XGamma package does not yield same number of events in Combined and stand-alone mode.
	L0Muon crashes with Hbook output.
	GaudiPython cannot be used with POOL persistency. Use ROOT data instead.
	Some links to MC are not up-to-date and might not work because the necessary information is not saved in the Brunel output. Please notify all unexpected behaviour.
