+* Fix failure when querying views that use table functions.  ({issue}`13944`)
+
+## BigQuery connector
+
+* Add support for [column and table comments](/sql/comment). ({issue}`13882`)

+* Fix performance regression when reading Parquet data. ({issue}`14094`)
+
+## Hive connector
+
+* Add verification for files written by the optimized Parquet writer. This can
+  be configured with the [`parquet.optimized-writer.validation-percentage`
+  configuration property](hive-parquet-configuration) or the
+  `parquet_optimized_writer_validation_percentage` session property. ({issue}`13246`)
+* Improve optimized Parquet writer performance for
+  [structural data types](structural-data-types). ({issue}`13714`)
+* Fix performance regression in reading Parquet files. ({issue}`14094`)
+
+## Iceberg connector
+
+* Improve performance when writing
+  [structural data types](structural-data-types) to Parquet files. ({issue}`13714`)
+* Improve performance of queries that contain predicates involving `date_trunc`
+  on `date` or `timestamp` partition columns. ({issue}`14011`)
+* Fix incorrect results from using the `[VERSION | TIMESTAMP] AS OF` clause when
+  the snapshot's schema differs from the current schema of the table. ({issue}`14064`)
+* Prevent `No bucket node map` failures when inserting data. ({issue}`13960`)

+  the default threshold before the predicate is compacted. ({issue}`14029`)
+
+## PostgreSQL connector
+
+* Fix failure when setting a column comment with special characters. ({issue}`14058`)
+
+## Redshift connector
+
+* Fix failure when setting a column comment with special characters. ({issue}`14058`)
+

+
+* Add the `SystemAccessControl.checkCanGrantExecuteFunctionPrivilege` overload,
+  which needs to be implemented to allow views that use table functions. ({issue}`13944`)
+* Add the `ConnectorMetadata.applyJoin` overload. It provides the connector
+  with a join condition that is as complete as possible to represent using
+  `ConnectorExpression`. Deprecate the previous version of 
+  `ConnectorMetadata.applyJoin`. ({issue}`13943`)
