Patch Release v4.2.3 is now available for your system. Patch releases are intended to be minimally disruptive to your system and do not contain new functionality. However, please read release notes and change log below and apply the patch during an appropriate service window.
The interface for policy creation previously allowed the user to create policies that were not supported by the policy engine. This only applied to policies for directive events; more conditions were available in the UI then the policy engine supported. This means some users may have policies existing in their system that are not being completely enforced. Take note of any policies for directive events that have 'source' and 'destination' as conditions. The logic in these policies will have to be recreated, either by creating policies that filter the events that trigger the directive, or by adding the conditions to the directive itself.
