2019-10-08 Brunel v55r2

This version uses Rec v24r2, Lbcom v23r0p2, LHCb v45r2, Gaudi v32r2 and LCG_96b with ROOT 6.18.04, and SQLDDDB v7r*, ParamFiles v8r*, FieldMap v5r*, AppConfig v3r*

This version is released on run2-patches branch and is intended for reconstruction of Run1 or Run2 data. For Run3, use a version released on master branch

This version is a placeholder for reconstruction improvements that took place after Reco14 and that could be included in an eventual reprocessing of Run1 or Run2 data.
