============= 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. 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.
