Changelog for the c-ares project
+* September 18
+
+- Added constants that will be used by ares_getaddrinfo
+
+- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it is
+ available to ensure it works properly in a threaded environment.
+
* September 10
- configure fix for detecting a member in the sockaddr_in6 struct which failed
