Today KDE release Plasma 5.21 biggest update, following new features are there in plasma 5.21
New Application Launcher
Find, reach and run your apps faster and easier than ever with Plasma’s new app launcher.
The new launcher features two panes to make it simple to locate your programs and comes with improved keyboard, mouse, and touch input, boosting accessibility across the board.
Support for languages with right-to-left writing (such as Japanese and Arabic) has also improved. We have also included an alphabetical “All Applications” view, a grid view for your favorite tools, and placed all the power actions (“Sleep”, “Restart”, “Shut Down”, etc.) at the bottom of the launcher pop-up so they are always visible and available.
Last but not least, we have fixed most of the bugs reported by users, guaranteeing a smoother access to all your stuff.
If you prefer the old Kickoff app launcher however, it is only few clicks away in KDE’s software store.
Application theme improvements
Continuing with improvements to the look and feel, applications using Plasma’s default theme now have a refreshed color scheme and sport a brand new unified headerbar style with a clean, cool new look.
For All Changelogs watch video;
Meet Breeze Twilight: a combination of a dark theme for Plasma and a light theme for applications, so you can enjoy the best of both worlds. Find it in the Global Theme section of your Settings
Plasma System Monitor
Plasma System Monitor is a brand new app for monitoring system resources and is now an integral part of Plasma.
Plasma System Monitor provides a wide variety of different views, offering an overview page with information on important core resources, such as memory, disk space, network and CPU usage. It also provides a quick view of the applications consuming the most resources. This lets you easily locate and zap applications or processes that are slowing your computer down.
If you need more details, the Applications page shows you all the running applications along with detailed statistics and graphs. A process page is also available for per-process information, and History shows the evolution of the use of your machine’s resources over time.
Finally, you can also create your own new customized pages using the page editor. This lets you tailor the information you get from your system to your needs.
KWin and Wayland
KDE is pushing to have first class support for Wayland, and Plasma 5.21 makes massive progress towards reaching that goal.
We have extensively refactored the compositing code in KWin and the changes should reduce latency throughout all compositing operations. We have also added a control in the compositing settings so you can choose whether you prefer lower latency or smoother animations.
In addition, we have also added support for mixed-refresh-rate display setups on Wayland, e.g. you can have one screen refreshing at 144Hz and another at 60Hz, which is ideal for improving work-stations with multiple monitors. Preliminary support for multiple GPUs was also added on Wayland.
The virtual keyboard in Wayland has been improved and now supports GTK applications using the
text-input-v3 protocol. The support for graphical tablets has also been improved and now includes all the controls that were missing in the previous version, such as pad ring and pad buttons.
Apart from the numerous improvements in stability, there are quite a few Plasma components that are getting much better support in Wayland. KRunner, for example, is now able to list all open windows in Wayland, a new component in the panel’s system tray informs you of the keyboard layout, and we now support features required for GTK 4, so all GTK 4 applications will now work.
Plasma 5.21 brings a new page to System Settings: the Plasma Firewall settings. This configuration module lets you set up and configure a firewall for your system.
A firewall can help you protect your system from intrusion from outside or block information you want to keep private from leaving your machine. Plasma 5.21 provides a simplified way of configuring both UFW and firewalld, two of the most used firewall systems in Linux.
Multiple pre-existing configuration pages have been completely rewritten and are now cleaner and easier to use. This has been the case for the Accessibility, Desktop Session and SDDM configuration modules.
The Media Player widget’s layout has been improved and now includes the list of applications currently playing music in the header as a tab bar. Another upgrade is that the album cover now takes up the whole width of the widget.
Plasma has always been designed to adapt to all types of screens. It can work on a desktop but it’s also easily adaptable to work on a mobile, tablet or anything in between. In Plasma 5.21 we are adding two new components for mobile in the official release.
- The Plasma Phone Components contains the mobile shell but also specific Plasma widgets adapted for Plasma Mobile.
- QQC2 Breeze Style is a pure Qt Quick Controls 2 style. It visually fits in with the widget based desktop Breeze theme and was optimized for lower RAM and GPU usage.
