KDE’s new Union theming system gained initial support for styling QtWidgets-based apps (Akseli Lahtinen). It’s a first draft with known visual glitches, but a notable milestone. Plasma 6.8 is taking shape.

New features

• Plasma 6.8: Union theming for QtWidgets apps; built-in RDP server adapts quality to available bandwidth for steadier frame rates; Strongswan VPN now supports EAP-TTLS authentication.

UI improvements

• Plasma 6.7.5: Discover only offers .deb install on systems that natively support the format.
• Plasma 6.8:
  • Clipboard history now indicates when copied text was marked secret, instead of silently hiding it.
  • Screen-recording indicator appears only during actual recording.
  • Overview effect easier to trigger via four-finger touchpad swipe.
  • Digital Clock calendar event text fully selectable.
  • Less awkward dialog design for drawing-tablet pen button config.
  • Bluetooth widget’s “Configure” button moved to the standard location.
  • Enterprise Wi-Fi connection jumps straight to credential entry.
  • System Tray icons stay visible until their popup closes.
  • “Keep selection and clipboard the same” no longer disables unrelated settings.
  • Mass crashes now produce a single System Tray icon listing all crashes, not dozens.
• Frameworks 6.30: Better contrast for in-window Kirigami dialogs in dark themes; System Monitor graph legends request tabular numerals for alignment.

Bug fixes

• Plasma 6.6.7: Security fix — screen locker failed to lock under a specific screen-off + grace-period configuration.
• Plasma 6.7.5: Discover no longer hangs on update checks with the Snap backend and no upgradeable Snaps; non-KDE app crashes on dialog close fixed; pointer-movement regression in VMs with non-accelerated drivers fixed; RTL languages no longer block force-quit in System Monitor; malformed panel edit-mode tooltip fixed; DrKonqi no longer crash-loops until memory exhaustion.
• Plasma 6.8: Fixed Plasma’s second-most-common crash (during logout); Plasma Search “Defaults” button and non-default highlighting work correctly; all Kickoff widgets can return results for uninstalled apps; logout sound no longer needlessly delays logout.

Performance & technical

• Plasma 6.7.5: Improved HDR appearance with ICC profiles.
• Plasma 6.8: Better performance/power efficiency for full-screen content on Intel and NVIDIA GPUs with HDR, ICC profiles, or Night Light; HLG transfer function support in KWin; screen-casting latency cut by one frame; lower resource use for notification/Activities thumbnails and the Trash widget; Spectacle omits the alpha channel when unused; disabling a System Tray widget frees memory immediately; showConfigurationInterface() works in Plasma scripting; Plasma launches with a plain background if all wallpaper plugins are broken or missing.
• Frameworks 6.30: KWallet log spam removed along with the non-functional feature causing it.
• KDE Gear 26.12.0: System Settings’ Proxy page rewritten in QML, enabling Plasma Mobile support with a near-identical design.

KDE asks for help with the weekly report (via its Matrix room), general project involvement — noting donated time matters more than money and non-programmers are welcome — and financial donations covering operations, salaries, and contributor travel.
