Major changes
~~~~~~~~~~~~~
- Upgrade of PCRE1 to PCRE2. See :ref:`pcre-update-v1-to-v2` for more details.
-- Introducing the :ref:`Exception Policy's Master Switch <master-switch>`. This
- allows to setup a single policy for all traffic exceptions. This is a breaking
- change for the default behavior in the Exception Policies: in IPS mode, if an
- exception policy is not set, it will fall back to the the master switch now,
- instead of being ignored. Prevent this by disabling the master switch.
+- IPS users: by default various new "exception policies" are set to DROP
+ traffic. Please see :ref:`Exception Policies <exception policies>` for details
+ on the settings and their scope.
