============= Release 0.151

General Changes

• Fix issue where aggregations may produce the wrong result when task.concurrency is set to 1.
• Fix query failure when array, map, or row type is used in non-equi JOIN.
• Fix performance regression for queries using OUTER JOIN.
• Fix query failure when using the :func:!arbitrary aggregation function on integer type.
• Add various math functions that operate directly on float type.
• Add flag deprecated.legacy-array-agg to restore legacy :func:!array_agg behavior (ignore NULL input). This flag will be removed in a future release.
• Add support for uncorrelated EXISTS clause.
• Add :func:!cosine_similarity function.
• Allow :doc:/clients/tableau to use catalogs other than hive.

Verifier Changes

• Add shadow-writes.enabled option which can be used to transform CREATE TABLE AS SELECT queries to write to a temporary table (rather than the originally specified table).

SPI Changes

• Remove getDataSourceName from ConnectorSplitSource.
• Remove dataSourceName constructor parameter from FixedSplitSource.

.. note:: This is a backwards incompatible change with the previous connector SPI. If you have written a connector, you will need to update your code before deploying this release.
