+2007-07-18 HLT base
+ - analysis framework handles SOR and EOR events, GetRunNo/Type
+ added to AliHLTComponent
+
+2007-07-17 HLT base
+ - extended high-level component interface in order to allow header
+ buffer before TObjects
+ - ROOT memory file added
+ - ROOT file streamer added
+ - workaround for ROOT garbage collection causing crashes when
+ cleaning up input objects
+
+2007-05-09 version HLT-v0-6 tagged
+ Highlights
+ BASE libHLTbase version 3.1.0
+ - High level component interface implemeted
+ - framework for AliRoot reconstruction added
+ - HLT logging converted to AliLog, AliLog trap added in order to
+ be able to redirect messages written to AliLog
+ - module agents for HLT libraries imlemented
+ - all utility components now moved from HLTbase to AliHLTUtil
+ TPC libAliHLTTPC version 3.1.1
+ - DigitReaderPacked revived
+ - merger added to slice tracker
+ - improvements on the ESD conversion
+ TRD
+ - first version of components using offline reconstruction added
+ PHOS
+ -
+2007-04-27 HLT base
+ - memory leaks corrected
+ - AliLog support moved to libAliHLTUtil in order to keep
+ - libHLTbase free of AliRoot dependencies
+ - dynamic loading of AliLog support
+ - AliHLTFileWriter moved to libAliHLTUtil
+ - workaround for ROOT bug: in order to avoid crashes when unloading
+ dynamic libraries via gSystem, the libraries are not unloaded
+ further investigation necessary
+2007-04-17 HLT sample applications
+ - publisher for AliLoader trees added
+ - sample analysis chain added tp sample lib
+ - tutorial and documentation
+ - benchmark functionality added to AliHLTSystem
+2007-03-14 aliroot integration
+ - AliHLTSystem interface methods to AliHLTReconstructor implemeted
+ - AliHLTModuleAgent introduced for each HLT module, sample
+ agent added to libAliHLTSample
+ - AliHLTOfflineInterface base classes added
+ - AliHLTFilePublisher, AliHLTRootFileWriter/Publisher moved to
+ libAliHLTUtil (AliHLTFileWriter will follow when dep. to PHOS are
+ cleared)
+2007-03-09 logging system
+ - adapted to AliRoot logging system, messages printed out via AliRoot
+ message channel
+ - AliRoot logging methods can be used in the same way as in AliRoot
+ - HLT TPC logging methods fixed to be redirected to the common logging
+ channel
+ - handling of configurations corrected in order to cope with the
+ Root CINT garbage collection.
+ - TPCLib stand-alone build system changed in order to use AliRoot package
+ definition
+2007-03-01 changes by Gaute (TPC)
+ - added InterMerger to SliceTrackerComponent, can be switched off by
+ component argument 'disable-merger'
+ - new data type 'TRACKS' defined for TPC describing tracks in global
+ coordinates
+ - GlobalMergerComponent has TRACKS/TPC as output data type
+ - new component argument to ClusterFinderComponent: timebins <n> specifies
+ the number of timebins to overcome the discrepancy between simulated
+ and real data
+ - TPCEsdWriter adapted to new TRACKS/TPC data type
+2007-02-21
+ - high-level component interface added
+ - libHLTbase version 2:0:0
+
+2007-02-20 version HLT-v0-5 tagged
+
+2007-02-20
+ - Cellular Automaton tracker added to TPC Lib
+ - TPC OnlineDisplay updated to the latest version of the CERN HLT cluster
+ libAliHLTTPCDisplay version for the AliHLTGUI v 1.5.2
+ - TPC ESD writer component finalized
2007-02-05
- improvements in AliHLTFilePublisher/Writer
- - small fix in component handler to pipe log messages during registration
+ - minor fix in component handler to pipe log messages during registration
of standard components into right log channel
- the ProcessEvent method is now a method of the component base class,
the actual processing method to implement is DoProcessing
