    • Fixed an issue that could result in a error when querying sys.checks

    • Fixed an Admin-UI issue that caused the translation strings to not be loaded correctly.

    • Fixed an issue that only occurred in Enterprise Edition, when privileges are enabled. This issue would result in an exception about missing privileges being thrown, rather than the expected Unsupported Feature exception, when attempting operations on closed tables/partitions as a user.

    • Fixed an issue that caused a NullPointerException if REFRESH TABLE was executed on a table with closed partitions.

    • Fixed a regression which caused IS NOT NULL predicates on columns of type array(object) to not match correctly.

    • Fixed an issue that caused the aggregation to fail if an array containing a single item was passed as fractions.

    • Fixed a performance regression resulting in a table scan instead of a NO-MATCH if a subquery used inside a WHERE clause returns no result ().
