KDE Plasma 6.6.4 landed on 2026-04-07 as the latest bugfix update to the KDE desktop environment. The release follows the feature-rich Plasma 6.6 launch from February 2026, which brought new modules and feature refinements to the open source desktop.
As a point release, 6.6.4 bundles three weeks of accumulated fixes and updated translations contributed by KDE's volunteer community. While individual fixes are typically small in scope, they address real-world issues reported through KDE Bugzilla. The full list of changes is available in the 6.6.3 to 6.6.4 changelog.
Plasma 6.6.4 is available now through KDE's distribution partners. Users can reach the development team directly on the #Plasma Matrix channel or the Plasma-devel mailing list for feedback.
