-## c-ares version 1.28.1 - Mar 30 2024
-
-This release contains a fix for a single significant regression introduced
-in c-ares 1.28.0.
-
-* `ares_search()` and `ares_getaddrinfo()` resolution fails if no search domains
-  are specified. [Issue #737](https://github.com/c-ares/c-ares/issues/737)
-
-
-## c-ares version 1.28.0 - Mar 29 2024
+## c-ares version 1.29.0 - May 24 2024
 
 This is a feature and bugfix release.
 
 Features:
 
-* Emit warnings when deprecated c-ares functions are used.  This can be
-  disabled by passing a compiler definition of `CARES_NO_DEPRECATED`. [PR #732](https://github.com/c-ares/c-ares/pull/732)
-* Add function `ares_search_dnsrec()` to search for records using the new DNS
-  record data structures. [PR #719](https://github.com/c-ares/c-ares/pull/719)
-* Rework internals to pass around `ares_dns_record_t` instead of binary data,
-  this introduces new public functions of `ares_query_dnsrec()` and
-  `ares_send_dnsrec()`. [PR #730](https://github.com/c-ares/c-ares/pull/730)
+* When using `ARES_OPT_EVENT_THREAD`, automatically reload system configuration
+  when network conditions change. [PR #759](https://github.com/c-ares/c-ares/pull/759)
+* Apple: reimplement DNS configuration reading to more accurately pull DNS
+  settings. [PR #750](https://github.com/c-ares/c-ares/pull/750)
+* Add observability into DNS server health via a server state callback, invoked
+  whenever a query finishes. [PR #744](https://github.com/c-ares/c-ares/pull/744)
+* Add server failover retry behavior, where failed servers are retried with
+  small probability after a minimum delay. [PR #731](https://github.com/c-ares/c-ares/pull/731)
 
 Changes:
 
-* tests: when performing simulated queries, reduce timeouts to make tests run
-  faster
-* Replace configuration file parsers with memory-safe parser. [PR #725](https://github.com/c-ares/c-ares/pull/725)
-* Remove `acountry` completely, the manpage might still get installed otherwise. [Issue #718](https://github.com/c-ares/c-ares/pull/718)
+* Mark `ares_channel_t *` as const in more places in the public API. [PR #758](https://github.com/c-ares/c-ares/pull/758)
 
 Bugfixes:
 
-* CMake: don't overwrite global required libraries/definitions/includes which
-  could cause build errors for projects chain building c-ares. [Issue #729](https://github.com/c-ares/c-ares/issues/729)
-* On some platforms, `netinet6/in6.h` is not included by `netinet/in.h`
-  and needs to be included separately. [PR #728](https://github.com/c-ares/c-ares/pull/728)
-* Fix a potential memory leak in `ares_init()`. [Issue #724](https://github.com/c-ares/c-ares/issues/724)
-* Some platforms don't have the `isascii()` function.  Implement as a macro. [PR #721](https://github.com/c-ares/c-ares/pull/721)
-* CMake: Fix Chain building if CMAKE runtime paths not set
-* NDots configuration should allow a value of zero. [PR #735](https://github.com/c-ares/c-ares/pull/735)
+* Due to a logic flaw dns name compression writing was not properly implemented
+  which would result in the name prefix not being written for a partial match.
+  This could cause issues in various record types such as MX records when using
+  the deprecated API.  Regression introduced in 1.28.0. [Issue #757](https://github.com/c-ares/c-ares/issues/757)
+* Revert OpenBSD `SOCK_DNS` flag, it doesn't do what the docs say it does and
+  causes c-ares to become non-functional. [PR #754](https://github.com/c-ares/c-ares/pull/754)
+* `ares_getnameinfo()`: loosen validation on `salen` parameter. [Issue #752](https://github.com/c-ares/c-ares/issues/752)
+* cmake: Android requires C99. [PR #748](https://github.com/c-ares/c-ares/pull/748)
+* `ares_queue_wait_empty()` does not honor timeout_ms >= 0. [Issue #742](https://github.com/c-ares/c-ares/pull/742)
