In the Colors & Themes settings page, you’ll see a new “Save Current Theme” button, allowing to save current settings (e.g., colors, window decoration, icons, cursors, desktop and window layout) as a custom global theme with custom name and thumbnail image.
Your saved themes are displayed as the global theme choices. And, they can be used for the day and night theme switching feature.
The new version also introduced Plasma Setup, a new first-run wizard for Plasma desktop, to create user account, connect to network, and configure other important things after installed the desktop environment.
The Windows List widget has been updated with Open on Hover option, and ability to filter out windows not on the current desktop or activity. Zoom and Magnifier now has a new tracking mode, always keep the pointer at center of screen.

For more about Plasma 6.6, see the official announcement in KDE website.
The source tarballs for the new desktop release are available to download at KDE web-site via this link page.
As a Linux user, it’s recommended to wait for your distribution updates. Arch Linux has made Plasma 6.6 into its official Extra repository, and, Fedora has built it for the next 44 version.
For Ubuntu, plasma desktop is available through the community maintained universe repository. If Debian upstream includes plasma 6.6 before the Ubuntu 26.04 package import deadline, then the new desktop will be available in next KUbuntu 26.04.
KUbuntu also has an official PPA that backports new versions of KDE Platform, apps, and frameworks for the most recent KUbuntu release. Though, it probably won’t make 6.6 for current 25.10 due to Qt version mis-match.
