The KDE team announced the release of KDE Plasma 5.21 with many new features. In this quick guide, we explain the steps to upgrade to KDE Plasma 5.21 from 5.20. And give you a quick post update feedback.

The KDE Plasma 5.21 desktop brings several new features and improvements. This is probably one of the big releases from the team in terms of core-updates such as Wayland improvements, KWin changes. On the look and feel side, a new Global theme Breeze twilight is introduced, a shiny new wallpaper called ‘Milky Way’.

You can checkout the feature highlights of KDE Plasma 5.21 here.

If you are running earlier version of KDE Plasma, this is how you can upgrade to the latest version.

Post Upgrade Feedback

After I ran the upgrade on my test system, everything went smooth. I must say, the KDE Plasma team did a very good job for the upgrade process to work flawlessly.

The first reboot after the upgrade took around 1.5 minutes (approx) additional time for the Plasma login screen to appear. Which is fine, I believe.

The custom wallpaper did not change to the new Plasma wallpaper. This is also expected. The upgrade should not change any other user customization. Unfortunately, the new wallpaper is not displayed in the Desktop Settings -> Wallpaper in the first boot. Not sure why. But after I did another reboot, it worked fine – I can see the Milky Way wallpaper in the wallpaper dialog.

So overall, it is a very good release and flawless so far in my test. The response of the desktop itself is faster than earlier Plasma 5.20 thanks to KWin changes and other performance improvements.

Enjoy KDE!
