I had a hard time parsing this one, but the alternatives I've come up with aren't much better. Maybe someone else has an idea. If not this is fine.

* Add new optimizer rule to simplify expressions like ``cardinality(map_keys(m))`` into ``cardinality((m))``. Same for :func:`map_values` function.
* Add support for the following primitive types to Avro decoder: ``TINYINT``, ``SMALLINT``, ``INTEGER`` and ``REAL``.

Hive Connector Changes
____________
* Remove the configuration property ``hive.parquet.fail-on-corrupted-statistics`` and the session property ``parquet_fail_with_corrupted_statistics``.

Iceberg Connector Changes
_______________
* Remove the configuration property ``iceberg.native-mode``. Use ``iceberg.catalog.type`` instead.

Pinot Connector Changes
_____________
* Add support for Pinot ``TIMESTAMP`` and ``JSON`` types.
* Add support for Pinot version 0.9.3.
