Which Plasma version on Netrunner?

So I’m currently running KDE Neon, which given how Ubuntu is going, means I’m to rebuild in the not too distant future. So I was planning on Debian, and dealing with slower Plasma updates, but then came across Netrunner. So how up to date with Plasma does Netrunner plan to keep things? As in will Plasma 6 be available via Netrunner before it’s in Debian stable, or even Debian testing? Do you have a “testing” like Debian testing, for newer libs/Plasma 6, that matches with Debian testing?
