My understanding is that Manjaro package maintainers prefer to promote the latest KDE Plasma iteration after one or two point releases are issued. There have been 5 point releases. v5.25.0 was released in June.
Does anyone know why there has been a delay in distributing v5.25.x to stable clients?
I checked the announcements pages of the Manjaro forum sections (both stable-updates as well as testing-updates). I couldn’t find answer to my question.
The “delay”, as you call it, is probably due to Quality testing and control. Remember, there are many people that use Plasma, not just you or me. And it needs to be thoroughly tested and the kinks worked out. If you want it sooner, switch branches and help out with testing.
The users of latte-dock 10.8 might get frustrated as well with some inconsistencies and ui glitches. On my unstable install i dropped it and trying to figure out the best way to adapt for my workflow, and still comparing things with my testing install.
