+  - Changed handling of timeouts for unregistered connections: don't reset
+    the counter if data is received and disconnect clients earlier.
   - Fixed a format string bug in "connection statistics" messages to clients.
   - Removed unnecessary #define of "LOCAL", now use plain C "static" instead.
   - Channel topics are no longer limited to 127 characters: now the only limit
