KDE Plasma 5.8 Beta 1 (5.7.95) is now available in our plasma 5 repos together with the update to KDE Frameworks 5.26
Feel free to test Plasma 5.8 Beta 1 as this becomes the first LTS for Plasma 5 with 18 months support.

Existing Neptune Plasma 5 users just have to perform a normal update to get this new version.
