== General

* Fix correctness issue for :func:`array_min` and :func:`array_max` when arrays contain `NaN`.
* Fix planning failure for queries involving GROUPING that require implicit coercions in expressions
  containing aggregate functions.
* Fix failure in :func:`json_extract` for certain UTF-8 sequences.
* Fix potential workload imbalance when using topology-aware scheduling.
* Fix performance regression for queries containing ``DISTINCT`` aggregates over the same column.
* Add support for casting to `INTERVAL` types.
* Improve error handling when a `HAVING` clause contains window functions.
* Allow treating decimal literals as values of the DECIMAL type. This behavior can
  be turned on via the ``parse_decimal_literals_as_double`` session property or 
  ``parse-decimal-literals-as-double`` configuration option.
* Ignore case when sorting the output of `SHOW FUNCTIONS`.
* Improve rendering of BingTile type
* Add JMX counter to track the number of submitted queries.

== Accumulo

* Improve table scan parallelism.

== Hive

* Fix query failures for the file-based metastore implementation when partition column values contain the character ':'.
