source: svn/trunk/CHANGELOG@ 554

* Changes relative to V.1.8
   - new: ./configure for the installation
   - update: default jet algorithms have change in data cards
   - update: adding some missing "#include" statements due to a loss of 
     permissivity in recent g++ compilers.
   - update: by default, both 1-prong and 3-prong tau jets are stored. 
     It was only 1-prong before.
   - bug fix: bad distribution in associated number of tracks in jets
   - vertex coordinates available in the track collection (Vx, Vy, Vz)
   - track reconstruction efficiencies can now be floating numbers
   - minor addition in the $(SHARED) target rule of the Makefile
   - bug fix: the charge of the electrons in the Analysis. Electron collection 
     was the opposite of what it should have been
   - bug fix: idem for muons in Analysis.Muon
   - bug fix: adding some #include statements in classes in src/*, for compatibility
     with recent versions of g++, which are less permissive than in the past

| 16 August 2009: release Version1.8        |
 \-----------------------------------------/
* Changes relative to V.1.7b
   - LHE files were not processed correctly (empty Analysis/Trigger trees). 
     Now LHEFParticle derives from TRootC::GenParticle as it should.
   - additional data in the logfile : run date/hour + all names of used input files 
     (input event files, detector card, trigger card, beam files, particle table)
   - bug fix: it is now possible to read "delphes root files" as an input for Delphes (GEN tree)
   - bug fix: number of events to process is correct event if multiple files in the inputlist
   - updates in Resolution.cpp & Resolution_ATLAS.cpp
   - new method "invisible()" in PdgParticle, needed for invisible particles BSM
   - new : calorimeter endcaps. DetectorCard have been updated; however, 100% backward compatible
   - bug fix: btag was not properly working for (mis)tag efficiencies below 1%.
   - bug fix: misplaced "#" character in the DetectorCard for ATLAS (calorimeter resolution).
   - moving to ROOT::TRandom3 for random numbers

| 18 June 2009: release Version1.7b         |
 \-----------------------------------------/
  Bug fixes for V.1.7------
* Changes relative to V.1.7
   - small typos in "cout" removed
   - Nevents implemented in DetectorCards
   - bug removed in bad inputfile type identification (".hep" vs ".lhe")
   - bug removed with calotowers(BinEtaPhi) : now use the middle of the 
      tower and not its lower edge in eta and in phi
   - bug removed for compilation error with FROG (genMakefile) : 
      the options  -Dmacos/-Dlinux/-Dwindows are automatically added 
      in CXXFLAGS when required
   - 3 bugs removed in BField (omega*gammam ; units in r ; z_max). 
      Bfield validated.
   - new headers in each file with full references

 /-----------------------------------------\
| 12 March 2009: release Version1.5         |
 \-----------------------------------------/

 * Changes relative to V.1.4beta:
    - implementation of the energy flow
        - calotowers are first merged then smeared
        - photons are based on these calotowers: conservative approach
        - electrons are separately smeared according to the calotower
          resolution.
    - new: list of calorimeters ; CaloUtil added
    - new: constants moved from SmearUtil.* to D_Constants.* 
    - new: GenParticle class
    - ParticleUtil changed into D_Particle
    - tracks and Taujets have now a charge
    - output available as a LHCO (text) data file, in option
    - extensive test and correction of the Bfield
        - using now an exact computation, assuming solenoidal field
        - about 20% faster than iterative approach
    - charged lepton isolation: IsolPt available 
    - data cards
         - default names have been changed
         - more parameters for more flexibility
        

 /-----------------------------------------\
| 09 February 2009: release Version1.4beta  |
 \-----------------------------------------/

 * Changes relative to V.1.3beta:
    - new overal header and program output to screen.
    - new trigger cards ATLAS and CMS-like
    - new detector card ATLAS oriented
    - New input parameters in the datacard for very forward detectors
    - Modification of the Resolution.cpp code to run on the output of Delphes directly
    - #include statements have been cleaned ; more include paths 
      in the compilation, leading to easier #include statements.
    - extensive use of 'valgrind' for the search for memory leaks.
      No more explicit leak is in the code. The only leaks left are
      related to ROOT, to mcfio dependecy and to Hector.
      This implied the systematic addition of copy-constructor, 
      operator= and correct destructors in Delphes classes
    - update of the BField simulation; still in the case of B = Bz only
    - JetsUtil* files renamed to JetsUtil*
 * Private modifications in dependencies
    - memory leaks removed in FROG (applied on Frog v1.106)
    - systematic change of by-value parameters to "by-const-reference" 
      in Hector (applied on Hector v1.3.1)

 /-----------------------------------------\
|  29 January 2009: release Version1.3beta  |
 \-----------------------------------------/

 * Changes relative to V.1.2beta:
    - Cleaning of non necessary comments 
    - Removal of the minimal transverse momentum applied on tracks and calotowers when the magnetic field is simulated 
    - Correction of the FROG interface 
    - Addition of a new standalone code to run FROG on the analysis output ROOT file 
    - New magnetic field algorithm: exact computation in case of magnetic field having a Bz component only 
    - Time performance monitoring 
    - Cleaner tarball 
 * Known limitations of this release are:
    -Work is currently being done on eta/phi variables leading to some uncertainties on these quantities when the magnetic field is switched on



 /-----------------------------------------\
| 18 December 2008: release Version1.2beta  |

    - Reconstruction of jets: the number of defined cell 
      towers is now correctly taken into account by the 
      jet algorithms 
    - Input for jet reconstruction: calotowers instead 
      of generated particles 
    - Input datacard parameters now taken into account by
      the jets, very forward detectors, magnetic field 
      propagation steps

      magnetic field, very forward detectors, trigger and FROG 
      running
