Hello team!
We are happy to ship c-ares 1.31.0 into the world. Get it as always from
https://c-ares.org/
## c-ares version 1.32.0 - July 4 2024
This is a feature and bugfix release.
Features:
* Add support for DNS 0x20 to help prevent cache poisoning attacks, enabled
by specifying `ARES_FLAG_DNS0x20`. Disabled by default. [PR
#800](https://github.com/c-ares/c-ares/pull/800)
* Rework query timeout logic to automatically adjust timeouts based on
network
conditions. The timeout specified now is only used as a hint until there
is enough history to calculate a more valid timeout. [PR
#794](https://github.com/c-ares/c-ares/pull/794)
Changes:
* DNS RR TXT strings should not be automatically concatenated as there
are use
cases outside of RFC 7208. In order to maintain ABI compliance, the
ability
to retrieve TXT strings concatenated is retained as well as a new API to
retrieve the individual strings. This restores behavior from c-ares
1.20.0.
[PR #801](https://github.com/c-ares/c-ares/pull/801)
* Clean up header inclusion logic to make hacking on code easier. [PR
#797](https://github.com/c-ares/c-ares/pull/797)
* GCC/Clang: Enable even more strict warnings to catch more coding
flaws. [253bdee](https://github.com/c-ares/c-ares/commit/253bdee)
* MSVC: Enable `/W4` warning level. [PR
#792](https://github.com/c-ares/c-ares/pull/792)

* Windows: Fix building with UNICODE. [PR
#802](https://github.com/c-ares/c-ares/pull/802)

[74a64e4](https://github.com/c-ares/c-ares/commit/74a64e4)
