There were two additional updates after sp3 which brings the software version to 2017.1.1. These updates were not sr's or hotfixes, they're actual point updates including new features. As long as you are able to work on your current version productively, then I wouldn't recommend upgrading to the point releases. It's not likely they fixed your issues there as you observed earlier. I would wait until the 2018 release with sr1 or 2. We should have that soon anyway.
