Unreal Engine 4.17 Released!

Release Infos of version 4.17 look great; will there be an upgrade from 4.16.3 to 4.17 so that I don’t need to download all 6 GBs or more again? I launched the installer EpicInstaller-6.1.0.msi for 4.17, but it asks me to either REPAIR or REMOVE the current version. I found no option to upgrade. So do I have to uninstall v4.16.3 completely before installing v4.17 ?
