Hi! If you are feeling adventurous and are using Sid, then you can help by testing Plasma 5.20.4 from experimental. I installed it using
apt install -t experimental plasma-base "plasma-base" is a new package to keep the versions of all Plasma packages in lock step. But beware currently Qt 5.15.2 is entering into Sid. It may need a day or two to complete. Be extra careful during that time. Also you can help test new application 20.12 packages as they enter unstable. Use them and report any issues you find with them. Please do this only if you feel up to it and are willing to keep the pieces in case something breaks. Of course you can always ask for help here, but it would be good if you are willing to do your best to resolve and diagnose issues on your own first and then if need be report with as much detail as possible. If unsure whether it is really a Debian bug or you like to learn about which package to report the bug for, feel free to ask here first. So far I am very happy with Plasma 5.20.4 and those KDE application packages I upgraded. I thank Norbert, Aurélien, Sandro who is in the process to upgrade KDEPIM packages to 20.08.3, Dmitry and everyone else who is involved with upgrading the packages or helps testing them. Thank you, -- Martin
