 ### Features Added
 
 - [[#6535]](https://github.com/Azure/azure-sdk-for-cpp/issues/6535) Enable SSL caching for libcurl transport by default, which is backwards compatible behavior with older libcurl versions, so using the default settings won't result in transport error when using libcurl >= 8.12. The option is controlled by `CurlTransportOptions::EnableCurlSslCaching`, and is on by default. (A community contribution, courtesy of _[sushshring](https://github.com/sushshring)_)
