============= Release 0.118

General Changes

• Fix planning error for UNION queries that require implicit coercions.
• Fix null pointer exception when using :func:!checksum.
• Fix completion condition for SqlTask that can cause queries to be blocked.

Authorization

We've added experimental support for authorization of SQL queries in Presto. This is currently only supported by the Hive connector. You can enable Hive checks by setting the hive.security property to none, read-only, or sql-standard.

.. note::

The authentication support is experimental and only lightly tested. We are
actively working on this feature, so expect backwards incompatible changes.
See the ``ConnectorAccessControl`` interface the SPI for details.
