According to updated development schedule for GNOME 45 on GNOME Wiki!, next major release of GNOME is set to be on 20 September 2023. Beforehand, GNOME 45 alpha release is due on 1 July 2023 to be followed by beta release on 5 August.
With GTK4 and Libadweita introduced in recent updates, GNOME now looks really modern as a desktop environment. But some included apps haven’t adopt the new design language yet. In the next version, new camera app Snapshot and image viewer app Loupe are expected to replace Cheese and Eye Of GNOME respectively.
