How is this related to Valtio?

[KrishnaPG]

pmndrs already seem to have a state management library:https://github.com/pmndrs/valtio

It is not clear how this and Valtio are related? and more importantly, which one to be used? (e.g. is Valtio going to be deprecated?)

I'm moving this to a discussion since it isn't really an issue.

Valtio is not being deprecated. Poimandres actually has a few state management libraries. Zustand, Jotai, Valtio and now Koota. They are all different models of state management and you can pick the one that fits your needs and style of working best. Here is a good comparison of Zustand, Jotai, Valtio and others https://zustand.docs.pmnd.rs/getting-started/comparison

Unlike all the others Koota is optimized for real-time speed. That means the way you write state will be different than you are used to but the up side is a much faster app. In a lot of cases, the speed Koota provides is not necessary and the other state management libraries would do fine with simpler APIs. Try both out and see what you like. If you have an example state problem you want to compare, I can show you how I would solve it with Koota.
