Warning:

Note that the following enums are removed.

- CURLE_SSL_CACERT

- CURLOPT_DNS_USE_GLOBAL_CACHE

You can use CURLE_PEER_FAILED_VERIFICATION instesd of CURLE_SSL_CACERT.

You can use CURLOPT_SHARE instead of CURLOPT_DNS_USE_GLOBAL_CACHE.

Note that default HTTP version is changed from HTTP/1.1 to HTTP/2.

If version isn't specified, curl attempts HTTP/2 only. It will fall back to HTTP/1.1 if HTTP/2 can't be negotiated with the HTTS server.

You can use CURL_HTTP_VERSION_1_1 to enforce HTTP 1.1 requests.

More details on HTTP version can be found from CURLOPT_HTTP_VERSION.
