COSMIC Epoch 1.0.15 was released today, June 4, 2026, bringing Wayland Pointer Constraints to the desktop environment. This implementation is intended to provide a "better gaming experience," as noted by Phoronix, by allowing games to lock the mouse cursor within their window or hide it completely. This functionality is crucial for many game types as it prevents accidental mouse movement outside the game window, improving immersion and control. The update focuses on core functionality; features like the new "Frosted Glass" UI option are not yet integrated into this release.
