+*********************************** NOTE **********************************
+The v5 versions of rsyslog feature a greatly redesigned queue engine. The
+major theme for the v5 release is twofold:
+
+a) greatly improved performance
+b) enable audit-grade processing
+
+Here, audit-grade processing means that rsyslog, if used together with
+audit-grade transports and configured correctly, will never lose messages
+that already have been acknowledged, not even in fatal failure cases like
+sudden loss of power.
+
+Note that large parts of rsyslog's important core components have been
+restructured to support these design goals. As such, early versions of
+the engine will probably be less stable than the v3/v4 engine.
+
+Also note that the initial versions do not cover all and everything. As
+usual, the code will evolve toward the final goal as version numbers
+increase.
