+Release 0.254
+=============
+
+**Details**
+===========
+
+General Changes
+_______________
+* Fix a bug where queries that have both remote functions and a local function with only constant arguments could throw an ``IndexOutOfBoundException`` during planning. The bug was introduced by :pr:`16039`.
+* Fix a CPU regression for queries using :func:`element_at` for ``MAP``. Introduced by :pr:`16027`.
+* Add fragment result caching support for ``UNNEST`` queries.
+* Add :func:`poisson_cdf` and :func:`inverse_poisson_cdf` functions.
+* Add memory tracking in ``TableFinishOperator`` which can be enabled by setting the ``table-finish-operator-memory-tracking-enabled`` configuration property to ``true``. Enabling this property can help with investigating GC issues on the coordinator by allowing us to debug whether stats collection uses a lot of memory.
+* Remove spilling strategy ``PER_QUERY_MEMORY_LIMIT`` and add configuration property ``experimental.query-limit-spill-enabled`` and session property ``query_limit_spill_enabled``. When ``query_limit_spill_enabled`` is set to ``true`` and the spill strategy is not ``PER_TASK_MEMORY_THRESHOLD``, then we will spill whenever a query uses more than the per-node total memory limit in combined revocable and non-revocable memory.
+
+Hive Changes
+____________
+* Fix a bug where the files would not be sorted when inserting into bucketed sorted tables with Glue.
+* Add support for validating the values returned from the partition cache with the actual value from Metastore. This can be enabled by setting the configuration property ``hive.partition-cache-validation-percentage``.
+* Add support for allowing to match columns between table and partition schemas by names when the configuration property ``hive.parquet.use-column-names`` or the hive catalog session property ``parquet_use_column_names`` is set to ``true``. By default they are mapped by index.
+* Add support for configuring the Glue endpoint URL. :doc:`/connector/hive`.
+* Add support for accessing tables in Glue metastore that do not have a table type.
+* Add support for the S3 Intelligent-Tiering storage class writing data. This can be enabled by setting the configuration property ``hive.s3.storage-class`` to ``INTELLIGENT_TIERING``.
+* Add configuration property ``hive.metastore.glue.max-error-retries`` for the maximum number of retries for glue client connections. The default value is 10.  :doc:`/connector/hive`.
+
+Presto On Spark Changes
+_______________________
+* Optimize Driver commit memory footprint.
+* Add session property ``spark_memory_revoking_threshold`` and configuration property ``spark.memory-revoking-threshold``. Spilling is triggered when total memory is beyond this threshold.
+
+SPI Changes
+_______________________
+* Add support for custom query prerequisites to be checked and satisfied through ``QueryPrerequisites`` interface. See :pr:`16073`.
