 ## Columnar Format Notes
 
+A `VariableShapeTensorType` was added to the Arrow specification as a canonical extension type. ([GH-24868](https://github.com/apache/arrow/issues/24868)).
+
+Motivated by recent innovations in DuckDB and Meta's Velox engine, new "view" data types were added to the Arrow columnar format spec. 
+
+* 16-byte StringView and BinaryView data type which enables better buffer reuse, faster "false" string comparisons (due to maintaining a prefix) and short string inlining. ([GH-35627](https://github.com/apache/arrow/issues/35627)).
+* ListView and LargeListView types for more performant "out-of-order" building and processing of lists and better buffer reuse ([GH-37876](https://github.com/apache/arrow/issues/37876)).

 ## Arrow Flight RPC notes
 
 A new RPC method was added to allow polling for completion in long-running queries as an alternative to the blocking GetFlightInfo call ([GH-36155](https://github.com/apache/arrow/issues/36155)). Also, `app_metadata` was added to `FlightInfo` and `FlightEndpoint` ([GH-37635](https://github.com/apache/arrow/issues/37635)).
