   Changelog for the c-ares project
 
+* May 19 2009 (Yang Tse)
+- Introduced ares_library_init() and ares_library_cleanup() functions.
+
+  This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets
+  using c-ares 1.6.1 can still survive without calling these functions. Read all
+  the details on ares_library_init(3) and ares_library_cleanup(3) man pages that
+  are included.
+
+  curl/libcurl 7.19.5 is fully compatible with c-ares 1.6.1 on all systems.
+
+  In order to use c-ares 1.6.1 with curl/libcurl on Win32/64 systems it is
+  required that curl/libcurl is 7.19.5 or newer. In other words, it is not
+  possible on Win32/64 to use c-ares 1.6.1 with a curl/libcurl version less
+  than 7.19.5
+

 - Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to
   only expose functions starting with ares_.

  o ares_gethostbyname() now supports 'AF_UNSPEC' as a family for resolving
    either AF_INET6 or AF_INET
  o a build-time configured ares_socklen_t is now used instead of socklen_t
+ o new ares_library_init() and ares_library_cleanup() functions
 
 Fixed:
 
  o ares_parse_*_reply() functions now return ARES_EBADRESP instead of
    ARES_EBADNAME if the name in the response failed to decode
  o only expose/export symbols starting with 'ares_'
+ o fix \Device\TCP handle leaks triggered by buggy iphlpapi.dll
 
 Thanks go to these friendly people for their efforts and contributions:
