* $curlopt will return in 6.1 but in WrapperConfig with a proper setup instead. * * This array is not in use and seems to be unused for a long time (discovered in april 2020). The discovery * is based on the fact that CURLOPT_SSLVERSION was set to the value 4 (CURL_SSLVERSION_TLSv1_0) which * should've not worked properly with for example omnitest.resurs.com. Instead of using TLS 1.0, netcurl * is configuring everything on fly and is actually no longer using this part of the module. Instead, * CURLOPT_SSLVERSION is set to CURL_SSLVERSION_DEFAULT which means that curl tries to automatically * discover which TLS version that should be used. This is why the TLS connectivity "always" works.
