+- Update to version 0.12.3:
+  * Fixed crash when no DTLS ciphersuite is negotiated.
+  * Fixed crash happening arbitrarily depending on handled string 
+    sizes (#197).
+  * Fixed compatibility issue with GnuTLS 3.3.x (#201).
+  * occtl: print the TLS session information, even if the DTLS 
+    channel is not established.
