The KDE Project has announced that its Plasma 6.6 desktop environment will arrive on February 17, 2026, introducing a range of features aimed at improving customization, accessibility, and hardware integration. Key additions include adjustable frame borders and a new login manager, addressing long-standing user requests for more flexible visuals. Beta versions will be available starting January 13 for testing.
The KDE Plasma 6.6 desktop environment is scheduled for release on February 17, 2026, bringing significant updates to Linux users seeking greater control over their interfaces. According to reports from the KDE Project, this version introduces a new "Plasma Login Manager" that could replace SDDM in distributions like Fedora Linux 44, CachyOS, and EndeavourOS, streamlining the login process.
A standout feature is the ability to adjust frame border intensity and contrast for Breeze-themed elements, a customization option users have requested for years. This allows for subtler or more pronounced outlines around panels and widgets, supporting minimalist designs or high-contrast needs for accessibility. Previously hardcoded, the frame contrast is now configurable via the system's color scheme, affecting QtQuick windows, QtWidgets, and Plasma SVG files. Building on Plasma 6.5's fully rounded window corners, this refinement enhances visual coherence without sacrificing usability.
Other enhancements include visual sharpness adjustments for content on screens running Linux kernel 6.19, a USB portal for sandboxed app access to devices, and OCR integration in the Spectacle screenshot tool. Users can now exclude specific windows from recordings, emulate XRandr in KWin for better XWayland app support, and apply per-DRM-plane color pipelines. Security improves with Wi-Fi passwords stored in root-owned locations, while Wayland sees better cross-app activation and a QR code in the Networks widget for easier connections.
The Application Dashboard gains color scheme customization—remaining dark by default—and resizable sections between Favorites and Applications. Battery management on laptops is refined, alongside support for colorblind users, screen mirroring, custom modes, and automatic brightness via ambient light sensors. Wayland adds "Slow Keys" accessibility, and OpenBSD compatibility is bolstered. Additional tweaks address HDR in Wine/Proton for Windows games, opacity rules for picture-in-picture, and the oo7 Secret Service provider.
System Settings and default widgets, such as Kickoff, Bluetooth, and Weather, receive numerous improvements. Beta testing begins January 13, with a second beta on January 27. While some users praise these cosmetic and functional upgrades, others, in community comments, express frustration over perceived neglect of core usability issues like scrollbar configurability.
