State of the DOTS system

Hello, I was wondering when the new DOTS system will finally get out of previews? I also wonder what Unity means by preview instead of beta?

Does that mean that if I make a project with the DOTS system, any update could potentially break them significantly? Or is it that it still lacks keys feature to be considered complete?

Also, is the DOTS system is meant to be the new normal by default, or it is only useful for AAA projects, like an RTS that has thousand of AI agents or HDRP project that need every bit of optimisation.

The DOTS forum is probably a better place to ask about the state of DOTS

Unity has a system where for individual features they are referred to as either experimental or preview if they are included in a release but are in an unfinished state. Alpha/Beta is used for early releases of builds themselves.

Ok !

Here is a thread about visibility changes to preview packages in Unity 2020.1:

Some DOTS packages were affected by that and are listed in that thread.
