General Changes --------------- * Fix resource leak in query queues. * Fix NPE when writing null ``ARRAY/MAP`` to Hive. * Fix :func:`json_array_get` to handle nested structures. * Fix ``UNNEST`` on null collections. * Fix a regression where queries that fail during parsing or analysis do not expire. * Make ``JSON`` type comparable. * Added an optimization for hash aggregations.
