curl/ares/RELEASE-NOTES
Yang Tse 35d4c57051 - Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and
ares_addr6ttl in order to prevent name space pollution, along with
  necessary changes to code base and man pages.This change does not break
  ABI, there is no need to recompile existing applications. But existing
  applications using these structs with the old name will need source code
  adjustments when recompiled using c-ares 1.6.1.

This is what's new and changed in the c-ares 1.7.0 release:
Changed:
o in6_addr is not used in ares.h anymore, but a private ares_in6_addr is
instead declared and used
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
o new --enable-curldebug configure option
o ARES_ECANCELLED is now sent as reason for ares_cancel()
o added ares_parse_srv_reply()
o added ares_parse_txt_reply()
o new --enable-symbol-hiding configure option
o addrttl and addr6ttl structs renamed to ares_addrttl and ares_addr6ttl
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
o init without internet gone no longer fails
o out of bounds memory overwrite triggered with malformed /etc/hosts file
o function prototypes in man pages out of sync with ares.h
Thanks go to these friendly people for their efforts and contributions:
