  • Fix potential incorrect results for aggregations involving FILTER (WHERE ...) when the condition is a reference to a table column. (#2267)
  • Allow renaming views with ALTER VIEW. (#1060)
  • Add error_type and error_code columns to system.runtime.queries. (#2249)

Security Changes#

Hive Connector Changes#

  • Fix incorrect query results when reading timestamp values from ORC files written by Hive 3.1 or later. (#2099)
  • Fix a CDH 5.x metastore compatibility issue resulting in failure when analyzing or inserting into a table with date columns. (#556)
  • Reduce number of metastore calls when fetching partitions. (#1921)
  • Support reading from insert-only transactional tables. (#576)
  • Deprecate parquet.fail-on-corrupted-statistics (previously known as hive.parquet.fail-on-corrupted-statistics). Setting this configuration property to false may hide correctness issues, leading to incorrect query results. Session property parquet_fail_with_corrupted_statistics is deprecated as well. Both configuration and session properties will be removed in a future version. (#2129)
  • Improve concurrency when updating table or partition statistics. (#2154)
  • Add support for renaming views. (#2189)
  • Allow configuring the hive.orc.use-column-names config property on a per-session basis using the orc_use_column_names session property. (#2248)

Kudu Connector Changes#

  • Support predicate pushdown for the decimal type. (#2131)
  • Fix column position swap for delete operations that may result in deletion of the wrong records. (#2252)
  • Improve predicate pushdown for queries that match a column against multiple values (typically using the IN operator). (#2253)

MongoDB Connector Changes#

  • Add support for reading from views. (#2156)

PostgreSQL Connector Changes#

  • Allow converting unsupported types to VARCHAR by setting the session property unsupported_type_handling or configuration property unsupported-type-handling to CONVERT_TO_VARCHAR. (#1182)

MySQL Connector Changes#

  • Fix INSERT query failure when GTID mode is enabled. (#2251)

Elasticsearch Connector Changes#

  • Improve performance for queries involving equality and range filters over table columns. (#2310)

Google Sheets Connector Changes#

  • Fix incorrect results when listing tables in information_schema. (#2118)

SPI Changes#
