  • Add support for casting between number and json. (#28394)
  • Improve performance of json_value and json_table by evaluating ON EMPTY and ON ERROR clauses lazily. (#28969)
  • Add support for DESCRIBE OUTPUT with inline queries, allowing direct description of query results without requiring a PREPARE statement. For example, DESCRIBE OUTPUT (SELECT * FROM nation). (#28002)

JDBC driver​

  • Add support for the variant type. (#29046)
  • Add support for transparent OAuth2 token refresh when using the JDBC accessToken connection property against a server configured with http-server.authentication.oauth2.refresh-tokens=true. Previously, such connections failed with 401 Unauthorized once the embedded access token expired. (#29264)

  • Reduce memory usage when writing files to S3. (#28488)
  • Reduce query planning time by reading metadata and protocol information from Delta checksum files. This optimization can be disabled by setting the delta.load-metadata-from-checksum-file configuration property or load_metadata_from_checksum_file session property to false. (#28381)
  • Fix DELETE deleting incorrect rows on Delta Lake tables backed by Parquet files with column indexes, particularly when the table was written by Apache Spark. (#28885)
