+-----------------------
+
+### Changes
+- Add TCP transport for syslog forwarding per RFC 6587.  Two syntaxes
+  supported for forwarding: `@@host:port` and `tcp://host:port`.  For
+  receiving: `listen tcp://addr:port`.  Uses octet counting framing
+  for sending, supports both octet counting and LF-delimited framing
+  for receiving
+
+### Fixes
+- Fix use-after-free in socket polling when callbacks close sockets
+  during iteration.  Could cause undefined behavior when handling
+  multiple concurrent TCP connections
