+NP: All IPv6 builds from before 9 June 2007 contain a cache corruption bug
 	and require a full cachedir deletion and rebuild.
 	Failure to do this will result in random segfaults and memory corruption
 
 KNOWN BUGS:
 
-PROBLEM:  Attempts to connect to Port 20480 instead of 80
-CAUSE:    error with ntohs() or htons() in the wrong place or vice versa.
-          _all_ locally stored port values should be HS in converted code.
-          Solved for all known events now, but this may reccur at any time
-          until conversion is completed.

 PROBLEM: Sockets created with IPv4 'family' cannot be use for IPv6 anywhere

-Non-Critical SegFaults (under normal mode Squid3 restarts cleanly)
-PROBLEM: When DNS result packet (only?) contains a CNAME it is ignored
-	 BUT the AAAA failover does not trigger (n > 0) this leaves the A records unqueried.
-	 IFF the CNAME pointed at ONLY 'A' RR the remote resolver usually does not
-	 add the relevant 'A" records to the additional section of the AAAA lookup.
-	CNAME now has to be explicitly recursed IFF no additional section records received.
