This is the version I'm running. At first my lag times became noticeable quicker, but now they have returned to pre-down-load stage. The very first time here after install, I was greeted with the "compatibility" issue, after making a minor correction, it has become non-existent here. However, my online CC bank does not like it, so one might have a small issue there.
