It appears that current Fedora Linux releases ship with OpenSSL 1.0.2h, which has been patched with the latest security fixes, but the team decided that it’s time to upgrade the OpenSSL libraries (libssl and libcrypto) to a newer, more advanced branch. Therefore, Fedora 26 Linux will ship with OpenSSL 1.1.0 by default, which will have a massive impact on the overall stability and security of the OS. There are many benefits of upgrading the OpenSSL libraries to the 1.1.0 branch, but the best one will be that they can keep up with any new improvements and bug fixes released upstream by the OpenSSL team. Of course, Fedora 26 will also provide compatible OpenSSL 1.0.2 packages for app that need it.
