This release of Plasma brings many nice touches for our users such as much improved high DPI support, KRunner auto-completion and many new beautiful Breeze icons. It also lays the ground for the future with a tech preview of Wayland session available. We're shipping a few new components such as an Audio Volume Plasma Widget, monitor calibration tool and the User Manager tool comes out beta.
New Audio Volume Applet
Our new Audio Volume applet works directly with Pulseaudio, the popular sound server for Linux, to give you full control over volume and output settings in a beautifully designed simple interface.
Application Dashboard alternative launcher
Plasma 5.4 brings an entirely new fullscreen launcher Application Dashboard in kdeplasma-addons: Featuring all features of Application Menu it includes sophisticated scaling to screen size and full spatial keyboard navigation.
The new launcher allows you to easily and quickly find applications, as well as recently used or favorited documents and contacts based on your previous activity.
Plasma 5.4 brings over 1400 new icons covering not only all the KDE applications, but also providing Breeze themed artwork to apps such as Inkscape, Firefox and Libreoffice providing a more integrated, native feel.
KRunner now remembers your previous searches and automatically completes from the history as you type.
Useful graphs in Networks applet
The Networks applet is now able to display network traffic graphs. It also supports two new VPN plugins for connecting over SSH or SSTP.
