============= Release 0.133 ============= General Changes --------------- * Add support for calling connector-defined procedures using :doc:`/sql/call`. * Add :doc:`/connector/system` procedure for killing running queries. * Properly expire idle transactions that consist of just the start transaction statement and nothing else. * Fix possible deadlock in worker communication when task restart is detected. * Performance improvements for aggregations on dictionary encoded data. This optimization is turned off by default. It can be configured via the ``optimizer.dictionary-aggregation`` config property or the ``dictionary_aggregation`` session property. * Fix race which could cause queries to fail when using :func:`concat` on :ref:`array_type`, or when enabling ``columnar_processing_dictionary``. * Add sticky headers and the ability to sort the tasks table on the query page in the web interface.
