- Security Improvements - UDF and pushdown functions can now be protected with data roles. Also the CommandContext can provide the Subject for custom security checks in UDFs.
- Cache Invalidation - Prepared plan and result set caches have will invalidate entries based upon metadata and data changes respectively. See the cache configuration maxStaleness setting and the Admin and Developer Guides for more.
- Runtime-updates of Metadata - ALTER statements have been added to change view/procedure/INSTEAD OF trigger (update procedure) definitions. A CREATE TRIGGER statement is also available to add an INSTEAD OF trigger (update procedures) to views. System procedures were added to set extension metadata and stat values. By default all effects of metadata updates happen only on running vdbs across the cluster. To make the changes persistent see the Developers Guide Runtime Updates section.
