@@ -9,10 +9,14 @@ Inspired from [Keep a Changelog](https://keepachangelog.com/en/1.0.0/)
 - Added Python and Ruby spec validators ([#646](https://github.com/opensearch-project/opensearch-api-specification/pull/646))
 - Added verbose output of the story being evaluated ([#646](https://github.com/opensearch-project/opensearch-api-specification/pull/646))
 - Added `_search` with `sort: direction` ([#658](https://github.com/opensearch-project/opensearch-api-specification/pull/658))
-- Added `_common.mapping:FlatObjectProperty` ([#661](https://github.com/opensearch-project/opensearch-api-specification/pull/661)) 
+- Added `_common.mapping:FlatObjectProperty` ([#661](https://github.com/opensearch-project/opensearch-api-specification/pull/661))
+- Added `_common.mapping:IcuCollationKeywordProperty` ([#]())
 
 ### Removed
 - Removed unsupported `_common.mapping:SourceField`'s `mode` field and associated `_common.mapping:SourceFieldMode` enum ([#652](https://github.com/opensearch-project/opensearch-api-specification/pull/652))
+- Removed unsupported `_common.mapping:DenseVectorProperty`, `_common.mapping:SparseVectorProperty`, and `_common.mapping:FlattenedProperty` ([#]())
+- Removed unsupported time series dimension properties and types ([#]())
+- Removed unsupported runtime field properties (`script`/`on_script_error`) on `NumberPropertyBase` ([#]()) 
 
 ### Fixed
 - Spec passes OpenAPI 3.1.0 validations ([#646](https://github.com/opensearch-project/opensearch-api-specification/pull/646))
