 This is a feature and bugfix release.
 
 Features:
- o Introduce optional (but on by default) thread-safety for the c-ares
+ o Add support for IPv6 link-local DNS servers.  Nameserver formats can now
-   library.  This has no API nor ABI implications. [2]
+   accept the %iface suffix, and a new ares_get_servers_csv() function was
- o resolv.conf in modern systems uses attempts and timeouts options instead
+   added to return servers that can contain the link-local interface name. [3]
-   of the old retrans and retry options. [6]
+
- o Query caching support based on TTL of responses. Can be enabled via
+Changes:
-   ares_init_options() with ARES_OPT_QUERY_CACHE. [12]
+ o Unbundle GoogleTest for test cases.  Package maintainers will now need to
+   require GoogleTest (GMock) as a build dependency if building tests. New
+   GoogleTest versions require C++14 or later. [6]
+ o Replace nameserver parsing code to use new memory-safe functions. [1]
+ o Replace the sortlist parser with new memory-safe functions. [5]
+ o Various warning fixes and dead code removal.
 
 Bug Fixes:
- o ares_init_options() for ARES_OPT_UDP_PORT and ARES_OPT_TCP_PORT accept the
+ o Old Linux versions require POSIX_C_SOURCE or _GNU_SOURCE to compile with
-   port in host byte order, but it was reading it as network byte order.
+   thread safety support. [2]

+ o A non-responsive DNS server that caused timeouts wouldn't increment the
- o ares_init_options() for ARES_FLAG_NOSEARCH was not being honored for

-   system configuration. Regression introduced in 1.22.0. [5]
- o Spelling fixes as detected by codespell. [7]
- o The timeout returned by ares_timeout() was truncated to milliseconds but
-   validated to microseconds which could cause a user to attempt to process
-   timeouts prior to the timeout actually expiring. [8]
- o CMake was not honoring CXXFLAGS passed in via the environment which could
-   cause compile and link errors with distribution hardening flags during
-   packaging. [9]
- o Fix Windows UWP and Cygwin compilation. [10]
- o ares_set_servers_*() for legacy reasons needs to accept an empty server list
-   and zero out all servers. This results in an inoperable channel and thus is
-   only used in simulation testing, but we don't want to break users.
-   Regression introduced in 1.21.0. [11]
