Curl Asynchronous RESolver library for applications which
need to perform DNS queries without blocking, or
need to perform multiple DNS queries in parallel.
Primary applications are servers with multiple clients and GUI programs.

I am running and building with the updated package in place of current
with no obvious issues, and would like to make this updated release
current for building with other packages, before trying to update to the
latest release which has build issues.
For changes since the previous Cygwin release, see below:
https://c-ares.org/changelog.html#c-ares-version-1161---may-11-2020
2020-05-11 1.16.1
Security:
- Prevent possible use-after-free and double-free in
ares_getaddrinfo() if ares_destroy() is called prior to
ares_getaddrinfo() completing.
Changes:
- Allow TXT records on CHAOS qclass. Used for retriving things like
version.bind, version.server, authoris.bind, hostname.bind, and
id.server.
Bug fixes:
- Fix Windows Unicode incompatibilities with ares_getaddrinfo()
- Silence false cast-align compiler warnings due to valid casts of
struct sockaddr to struct sockaddr_in and struct sockaddr_in6.
- MacOS should use libresolv for retrieving DNS servers, like iOS
- CMake build system should populate the INCLUDE_DIRECTORIES property
of installed targets
- Correct macros in use for the ares_getaddrinfo.3 man page
2020-03-13 1.16.0
Changes:
- Introduction of ares_getaddrinfo() API which provides similar output
(including proper sorting as per RFC 6724) to the system native API,
but utilizes different data structures in order to provide additional
information such as TTLs and all aliases.
Please reference the respective man pages for usage details.
- Parse SOA records from ns_t_any response
- CMake: Provide c-ares version in package export file
- CMake: Add CPACK functionality for DEB and RPM
- CMake: Generate PDB files during build
- CMake: Support manpage installation
Bug fixes:
- Fix bad expectation in IPv6 localhost test.
- AutoTools: use XC_CHECK_BUILD_FLAGS instead of XC_CHECK_USER_FLAGS to
prevent complaints about CPPFLAGS in CFLAGS.
- Fix .onion handling
- Command line usage was out of date for adig and ahost.
- Typos in manpages
- If ares_getenv is defined, it must return a value on all platforms
- If /etc/resolv.conf has invalid lookup values, use the defaults.
- Tests: Separate live tests from SetServers* tests as only live tests
should require internet access.
- ares_gethostbyname() should return ENODATA if no valid A or AAAA
record is found, but a CNAME was found.
- CMake: Rework library function checking to prevent unintended linking
with system libraries that aren’t needed.
- Due to use of inet_addr() it was not possible to return
255.255.255.255 from ares_gethostbyname().
- CMake: Fix building of tests on Windows
2018-10-23 1.15.0
Changes:
- Add ares_init_options() configurability for path to resolv.conf file
- Ability to exclude building of tools (adig, ahost, acountry) in CMake
- Android: Support for domain search suffix
- Report ARES_ENOTFOUND for .onion domain names as per RFC7686
Bug fixes:
- AIX build fix for trying to include both nameser_compat.h and
onameser_compat.h
- Windows: Improve DNS suffixes extracting from WinNT registry
- Fix modern GCC warnings
- Apply the IPv6 server blacklist to all nameserver sources, not just
Windows
- Fix warnings emitted by MSVC when using -W4
- Prevent changing name servers while queries are outstanding
- Harden and rationalize c-ares timeout computation
- Distribute ares_android.h
- ares_set_servers_csv() on failure should not leave channel in a bad
state
- Add missing docs to distribution
