The table below list new features introduced in Brunel version v23r2, relative to version v23r1
| Subsystem | Item | Responsible | Remarks |
| Framework | Use LHCB v15r2 | M.Cattaneo | |
| Dropped support for pre-2004 geometries | M.Cattaneo | Removed v200311.opts, RiSicbGeom | |
| Dropped valgrind support for gcc 2.95.2 | M.Cattaneo | Brunel.supp.gcc32 renamed Brunel.supp | |
| Relations and Links created in new "Relations" sequence, independent of monitoring | |||
| Event Model | Added depositedCharge() to ITCluster | M.Needham | ITEvent v13r1, ITAlgorithms v14r0. Backwards incompatible for POOL |
| Added one significant bit to time field of MuonDigit | A.Satta | MuonEvent v3r1, MuonAlgs v5r1 | |
| DST content | Replace old style "relations" with new style "links" for MC truth of ITClusters, OTClusters, VeloClusters, MuonCoords, L0Calo. Relations can be rebuilt from links when reading the DST. | O.Callot | AsctToLinker v1r0 |
| Removed all old L1 objects. To be replaced by new Trg objects (not yet done) | M.Cattaneo | ||
| Removed filtering of MCParticles/MCVertices (should be done in Gauss) | M.Cattaneo | ||
| Added OTDigits | M.Cattaneo | This is a temporary measure to avoid a code dump by POOL when it writes out OTClusters (that have a SmartRef to OTDigits which are not saved anywhere...) | |
| ST | Support for new TT layouts: 4-3-3-4 everywhere (default) and 4-2-1-1-2-4 in centre (option). See details here | M.Needham | Requires XmlDDDB v21r0 (backwards incompatible) STDet v1r0, ITAlgorithms v14r0, ITCheckers v2r0, LongTrack v1r10, Seeding v2r8, TrCheck v2r3, TrCleanEx v2r3, TrKShort v1r1, TrMatching v2r9, VeloTT v1r7 |
| Fix bug in IT beam pipe clearance, modify Silicon thickness | M.Needham | XmlDDDB v21r0 - details here. | |
| OT | OTDigits are rebuilt from RawBuffer | J.Nardulli | OTDAQ v1r0 |
| Muon | MuonDigits are rebuilt from RawBuffer | A.Satta | MuonDAQ v1r0 |
