Air

KDE developers are restoring the classic Oxygen and Air themes for the Plasma 6.7 release scheduled for June 16, 2026. The effort, led by Filip Fila and original Oxygen designer Nuno Pinheiro, aims to revive the themes' glassy aesthetics from the KDE 4 era in time for KDE's 30th anniversary. Both themes have seen significant updates to panels, widgets, and visual effects.
