ProtonUp-Qt, an open-source GUI that streamlines the installation and updating of Proton-GE and Wine-based compatibility layers, enabling Linux gamers to run Windows-exclusive titles on their preferred distributions, has rolled out the brand-new 2.14 version.
The key change in this release is the addition of Proton-EM, a new compatibility tool that expands gaming support for users who rely on custom Proton builds. At the same time, the NorthStar Proton tool has been removed, as it is no longer maintained.

It’s worth noting also that ProtonUp-Qt 2.14 has been tested on major Linux distributions, including Ubuntu 18.04 and newer, Fedora 34, and Manjaro 20.2.
For those looking to install ProtonUp-Qt, the recommended approach is to use Flathub or your favorite app store, with a Flathub release expected shortly after the current AppImage version. Alternatively, users can download the ProtonUp-Qt AppImage directly, make it executable, and launch it by double-clicking.
