    r551 r558  
    1 * Changes relative to V.1.8
     1* Changes relative to V.1.8
     2   - new: b-(mis)tag algorithms
     3       * pt/eta dependence for b-(mis)tagging ;
     4       * now also for gluon-jets
     5       * related changes in the datacard:
     6         deleted parameters: BTAG_b, BTAG_mistag_c, BTAG_mistag_l
     7         new parameters: BTAG_func_b, BTAG_func_c, BTAG_func_g, BTAG_func_l
     8   - new: Isolation: SumEt & SumPt added for muons & electrons
     9     NB 'SumPt' was before 'IsolPt' in muon collection only
     10   - datacard: change of several variable names!!!
     11       before    ->  new name
     12       ISOL_PT        -> ISOL_trk_PT
     13       ISOL_Cone      -> ISOL_trk_Cone
     14       ISOL_Calo_Cone -> ISOL_calo_Cone
     15       ISOL_Calo_ET   -> ISOL_calo_ET
     16       ISOL_Calo_Grid -> ISOL_calo_Grid
     17   - bug fix: EtRatio for muons
    218   - new: ./configure for the installation
    319   - update: default jet algorithms have change in data cards
