@@ -14,6 +14,8 @@ Can memory usage be reduced further? (e.g. better channel struct management)
Ability to load new certificate whilst running.
-JOINing a channel that is a substring of another channel breaks all sorts (e.g. both #blabouncer and #blabounce).
+Are any other strncmps incorrect (i.e. just checking a substring)?
+
+Topic is stored incorrectly when the setter's host was an IPv6 address (colon search issue?).
Crash when requesting 30 hour replay.
