 ## Validator Changes
 
-* Fix expression for con-3 properly (fix validation problem on some condition resources)
+* no changes
-* 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
 
-* fix problem where profile rendering had spurious 'slices for' nodes everywhere
+* no changes
-* 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)
