 	    Fix broken DNSSEC validation of ECDSA signatures.
 
 	    Add --dnssec-timestamp option, which provides an automatic
-	    way to detect when the system time becomes valid after boot
-	    on systems without an RTC, whilst allowing DNS queries before the
-	    clock is valid so that NTP can run. Thanks to
-	    Kevin Darbyshire-Bryant for developing this idea.

 	    Add --tftp-no-fail option. Thanks to Stefan Tomanek for
 	    the patch.
 
-	    Fix crash caused by looking up servers.bind, CHAOS text record,
-	    when more than about five --servers= lines are in the dnsmasq
-	    config. This causes memory corruption which causes a crash later.
-	    Thanks to Matt Coddington for sterling work chasing this down.

+            Fix crash in authoritative DNS code, if a .arpa zone 
+	    is declared as authoritative, and then a PTR query which
+	    is not to be treated as authoritative arrived. Normally, 
+	    directly declaring .arpa zone as authoritative is not 
+	    done, so this crash wouldn't be seen. Instead the 
+	    relevant .arpa zone should be specified as a subnet
+	    in the auth-zone declaration. Thanks to Johnny S. Lee
+	    for the bugreport and initial patch.
