-* no changes
+* Fix expression for con-3 properly (fix validation problem on some condition resources)
+* Fix FHIRPath bug using wrong type on simple elements when checking FHIRPath types
+* FHIRPath: Allow _ in constant names (per FHIRPath spec)
+* Fix value set rendering creating wrong references
+* Fix bug processing value set includes / excludes that are just value sets (no system value)
+* Alter processing of unknown code systems per discussion at ,https://chat.fhir.org/#narrow/stream/179252-IG-creation/topic/Don't.20error.20when.20you.20can't.20find.20code.20system and implement unknown-codesystems-cause-errors
+* Improve message for when elements are out of order in profile differentials
+
 
 ## Other code changes
 
-* no changes
+* fix problem where profile rendering had spurious 'slices for' nodes everywhere
+* Update SQL-On-FHIR implementation for latest cases, and clone test cases to general test care repository
+* Fix problem generating value set spreadsheets
+* fix concurrent modification error processing language translations
+* Check for null fetcher processing ConceptMaps (#1728)
