+ 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

+- 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.

++ 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.
