+
+### Bugfixes
+
+- Fixes long list of bugs listed in [Issue #352](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/352).
+  Fix A2: `VTraceHandler::calculateTraceSum_slidingWindow()` fRaw branch returned `FADC[1]` (second FADC sample, ped-subtracted) instead of the accumulated raw charge sum. Affected pedestal calculation path. ([#351](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/351))
+- Bug fix: non-XGB jobs no longer probe XGB sidecar files (E4)
+
+  XGB sidecar files (stereo and gamma-hadron) are now opened only when the active
+  reconstruction method and gamma-hadron cut type actually require them, eliminating
+  spurious ROOT file-open errors in non-XGB jobs. ([#352](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/352))
+- Bug fix: explicit NegWeightTreatment for TMVA Gradient BDT angular reconstruction
+
+  Added `NegWeightTreatment=Pray` to the default TMVA options in
+  `trainTMVAforAngularReconstruction` to match actual TMVA behaviour:
+  `BoostType=Grad` does not support `InverseBoostNegWeights` (TMVA's global
+  default) and silently replaces it with `Pray`; the options string now
+  declares this explicitly so the training configuration matches what is used. ([#353](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/353))
+
+### Maintenance
+
+- Updates to allow for compilation with ROOT >=v6.38. Adjustment of CI. ([#358](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/358))
