* 7.55.0 deprecates CURLINFO_CONTENT_LENGTH_DOWNLOAD in favour of a *_T
version, which returns curl_off_t instead of a double.
* 7.85.0 deprecates CURLOPT_PROTOCOLS and CURLOPT_REDIR_PROTOCOLS in
favour of *_STR variants, specifying the desired protocols via a
string.

I'm interested because one of the machines I use has just updated to the new libcurl and so QEMU no longer compiles there because of the deprecation warnings :-) -- PMM

Yes, I'm going through the patches right now that were stuck because the previous pull request was blocked by CI. Thanks, applied to the block branch. Kevin

I've also applied to my testing/next (for the same reason) just in case the block branch doesn't go in soon. -- Alex Bennée Virtualisation Tech Lead @ Linaro
