KDE has released Plasma 6.8 Beta 2, which includes significant updates such as Union theming for legacy QtWidgets apps and the integration of the Kup backup scheduler into the desktop environment. The Union theming engine aims to provide a consistent look across applications, although it is still buggy and requires user testing for improvements. Additionally, the update removes X11 login support in favor of Wayland, marking a shift in KDE's direction. Other enhancements include improved HDR support, default NVIDIA triple buffering, and various fixes across multiple modules, contributing to a more refined user experience

KDE released the second beta of Plasma 6.8 today, carrying the pre-release number 6.7.91 ahead of the stable launch later this year. The headline update expands Union theming to legacy QtWidgets apps like Dolphin and Kate, finishing the second half of the engine's public preview. Kup, the btrfs-based backup scheduler, joins Plasma as a first-class module, making automatic backups to an external disk straightforward. The build also cuts X11 login support, defaults NVIDIA triple buffering, and packs in HDR, screen recording, and remote desktop improvements.
