-- Prevent possible double-free in ares_getaddrinfo() if ares_destroy() is called
-

-  it would result in an invalid read and double-free due to calling end_hquery() twice.

-  Allow TXT records on CHAOS qclass (#321)
-  
-  Some DNS servers intentionally "misuse" the obsoleted CHAOS (CH) qclass to provide things like `version.bind`, `version.server`, `authors.bind`, `hostname.bind` and `id.server`.
-  
-  C-ares was not allowing such use cases.

-
-  CMake: Rework library function checking (#310)
-  
-  CHECK_LIBRARY_EXISTS(), while it takes a function name, does not actually verify the function exists in the library being evaluated. Instead, if the function is found in any dependent library, and the referenced library also exists, it returns true. This is not desirable.
-  
-  Wrap with a Macro to change the behavior.

-  Fixes: #307

-- [Dron Rathore brought this change]
-
-  Parse SOA records from ns_t_any response (#103)
-  
-  Added the capability of parsing SOA record from a response buffer of ns_t_any type query, this implementation doesn't interfere with existing T_SOA query's response as that too is treated as a list of records. The function returns ARES_EBADRESP if no SOA record is found(as per RFC).
-  
-  The basic idea of sticking to RFC that a ns_t_any too should return an SOA record is something open for discussion but I have kept the functionality intact as it was previously i.e the function returns ARES_EBADRESP if it doesn't find a SOA record regardless of which response it is parsing i.e. T_SOA or T_ANY.
-  
-  Note that asking for T_ANY is generally a bad idea:

-  Added CPack functionality for generating RPM or DEB packages (#283)
-  
-  Added CPack functionality for generating RPM or DEB packages
-  
-  ie: run `cpack -G RPM` (or "DEB") after building with CMake.
-  
-  The current configuration creates 3 separate packages for the shared library,
-  the development files and the tools.

-  ares_gethostbyname: Return ENODATA if no valid A or AAAA record found (#304)
-  
-  ares_gethostbyname() was returning ESUCCESS when no A or AAAA record was found but a CNAME pointing nowhere was present.  ENODATA should be returned instead, however the hosts pointer will still be present to provide the alias list.
-  
-  * Return ENODATA if no valid A or AAAA record found
-  * Fix and update test ParseAReplyNoData.
-  * Add test for new ENODATA behaviour in ares_gethostbyname.

-
-  test: Separate live tests from SetServers* tests (#299)
-  
-  Before this change, SetServers, SetServersPorts and SetServersCSV
-  contained test cases trying to make DNS queries with the google.com
-  hostname, which requires Internet connectivity. Tests with that
-  requirement should be defined in the ares-test-live.cc file and contain
-  "Live" prefix to filter them out with `--gtest_filter=-*.Live*` on
-  machines without Internet connectivity.

-- [Adam Majer brought this change]
-
-  Only count valid addresses when response parsing (#302)
-  
-  When ares_parse_a_reply or ares_parse_aaaa_reply is called in case
-  where another AAAA and A responses exist, the resulting ares_addrttl
-  count is invalid and the structure points to gibberish.
-  
-  This is a regression since 1.15.

-  
-  * Add CARES_BUILD_CONTAINER_TESTS CMake option to add ability to build the Linux-only containerized tests.
-  * Accept invalid /etc/resolv.conf lookup values
-  
-  Before this commit invalid `lookup` values resulted in c-ares not using
-  any lookups without any clear indication why. After this commit it uses
-  the default "fb".

-
-  Parallel A and AAAA lookups in `ares_getaddrinfo` (#290)
-  
-  A and AAAA lookups for ares_getaddrinfo() are now performed in parallel.
-  
-  For this change `ares_search` was removed from `ares_getaddrinfo`.
-  Instead `ares_query` in combination with `next_dns_lookup` are
-  doing the suffix search.
-  
-  Adding support for `.onion` addresses which are tested by
-  `TEST_F(DefaultChannelTest, GetAddrinfoOnionDomain)`

+  Parse SOA records from ns_t_any response (#103) 
+   
+  Added the capability of parsing SOA record from a response buffer of ns_t_any type query, this implementation doesn't interfere with existing T_SOA query's response as that too is treated as a list of records. The function returns ARES_EBADRESP if no SOA record is found(as per RFC). 
+   
+  The basic idea of sticking to RFC that a ns_t_any too should return an SOA record is something open for discussion but I have kept the functionality intact as it was previously i.e the function returns ARES_EBADRESP if it doesn't find a SOA record regardless of which response it is parsing i.e. T_SOA or T_ANY. 
+   
+  Note that asking for T_ANY is generally a bad idea:
