-On the 29th of December 2001, Jerome Etienne posted a security analysis of tinc
-1.0pre4. Due to a lack of sequence numbers and a message authentication code
-for each packet, an attacker could possibly disrupt certain network services or
-launch a denial of service attack by replaying intercepted packets. The current
-version adds sequence numbers and message authentication codes to prevent such
-attacks.
+Although tinc 1.1 will be protocol compatible with tinc 1.0.x, the
+functionality of the tincctl program may still change, and the control socket
+protocol is not fixed yet.
