+  fault-tolerant execution is enabled. ({issue}`15160`)
+* Add support for `CHECK` constraints in an `INSERT` statement. ({issue}`14964`)
+* Improve planner estimates for queries containing outer joins over a subquery
+  involving `ORDER BY` and `LIMIT`. ({issue}`15428`)

+  row filters. ({issue}`15583`)
+* Fix potential hang during shutdown. ({issue}`15675`)
+* Fix incorrect results when referencing a field resulting from the application
+  of a column mask expression that produces a `row` type. ({issue}`15659`)
+* Fix incorrect application of column masks when a mask expression references a
+  different column in the underlying table. ({issue}`15680`)
+
