==== Local Packages ====

 * Updated `c-ares` to 1.23.0:
 . This is a feature and bugfix release
 . Features:
  * Introduce optional (but on by default) thread-safety for the `c-ares` library; this has no API nor ABI implications
  * `resolv.conf` in modern systems uses `attempts` and `timeouts` options instead of the old `retrans` and `retry` options
  * Query caching support based on TTL of responses: can be enabled via `ares_init_options()` with `ARES_OPT_QUERY_CACHE`
 . Bug Fixes:
  * `ares_init_options()` for `ARES_OPT_UDP_PORT` and `ARES_OPT_TCP_PORT` accept the port in host byte order, but it was reading it as network byte order (regression introduced in 1.20.0)
  * `ares_init_options()` for `ARES_FLAG_NOSEARCH` was not being honoured for `ares_getaddrinfo()` or `ares_gethostbyname()` (regression introduced in 1.16.0)
  * Autotools MacOS and iOS version check was failing
  * Environment variables passed to `c-ares` are meant to be an override for system configuration (regression introduced in 1.22.0)
  * Spelling fixes as detected by `codespell`
  * 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
  * CMake was not honouring `CXXFLAGS` passed in via the environment, which could cause compile and link errors with distribution hardening flags during packaging
  * Fix Windows UWP and Cygwin compilation
  * `ares_set_servers_*()` for legacy reasons needs to accept an empty server list and zero out all servers, which 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)
