     analysis.nucleicacids' NucPairDist and WatsonCrickDist classes has been
     removed. Please use the `results.pair_distances` and `times` attributes
     instead (Issue #3744)
+  * RDKitConverter changes (part of Issue #3996):
+    * moved some variables (`MONATOMIC_CATION_CHARGES `and
+      `STANDARDIZATION_REACTIONS`) out of the related functions to allow users
+      fine tuning them if necessary.
+    * changed the sorting of heavy atoms when inferring bond orders and
+      charges: previously only based on the number of unpaired electrons, now
+      based on this and the number of heavy atom neighbors.
+    * use RDKit's `RunReactantInPlace` for the standardization reactions, which
+      should result in a significant speed improvement as we don't need to use
+      bespoke code to transfer atomic properties from the non-standardized mol
+      to the standardized one.
