The KDE Plasma 6.7 branch has been announced to transition to the beta testing stage, with the code base frozen to functional changes, only accepting corrections. The release of KDE Plasma 6.7 is scheduled for June 16. (Source)
Main changes in KDE Plasma 6.7 include:
- The addition of the user interface Plasma Bigscreen, designed for multimedia devices connected to TVs and projectors. The environment is optimized for use on large screens and can be controlled without a keyboard, using remote controls or a voice assistant. (Source)
- The implementation of a unified style engine called Union, which allows the use of different application styling technologies available in KDE. Styles are now in CSS format by default, as opposed to the previously used SVG. A new implementation of the Breeze theme has been created in CSS format. The Union engine consists of three layers:
- The input layer, implemented through plugins that parse input file formats with styles and convert them into an abstract description for rendering. Examples of input formats include SVG or CSS skins.
- The middleware, styled as a library that describes the data model and methods for applying styles to each element.
- The output layer contains plugins for converting the generic style generated by the middleware into rendering commands specific to a particular graphics stack. For example, the output can generate styles for QtQuick or Qt Widgets. (Source)
- The implementation in the KWin composite manager has been updated. (Source)
