PayPalThe KDE team have released the latest release for the Plasma desktop, with version 6.6.1 bringing quite a lot of bug fixing. As usual, a big new release with 6.6 that added numerous features also came with a number of problems that needed to be solved.
There's fixes for the Discover software centre with Flatpaks, Bluedevil bluetooth will no longer tell you about connection failures when there wasn't any, various improvements to the Kicker launcher and Task Manager but the biggest set of issues by far are the bugs solved in the window manager KWin.
Hopefully this release will fix up some problems you saw. Thankfully, my Plasma 6.6 on Fedora KDE has been running very nicely overall but good to see such rapid fixes come in.

I didn't even had issues with 6.6.0. But also I've been using it for like 3 days until today. 🤷♂️

There's fixes for the Discover software centre with FlatpaksI've come across random weird issues with this on my Fedora KDE boxes. Sometimes the Flathub source is listed under Settings, sometimes its not, sometimes its not listed and packages still update normally. It's hit or miss. Noticed it first on 6.5, but seems to be better/normal/fixed now on 6.6.
