Release Notes: Changes in this release include a fix for an ACL consistency, a fix for the rand_tcp_isns sysctl option, PaX updates, and better default ACL enforcement.

Release Notes: With this release, a milestone in the project has been reached. It is now possible to create a policy for the entire system with no configuration. The system performs a complex graph and heuristic analysis to create the policy, and then undergoes an automatic policy audit and correction to ensure the policy is truly least privilege. Learning for an entire role or a single process is supported as well.
