What means this "preview" thing by 4.3

Why is this release called “preview” instead of just 4.3.0? Is this something like a beta?
Should I install it? I have read some new problems about 4.3., should I wait better for the next release?
When it will be the next release? I’m using current 4.2.1 and don’t need urgent the new functions in 4.3.

Hi WarMachine -

4.3 is still in beta but it is close enough that we wanted to let users have some experience with it which helps us track down bugs which we may have missed. The release version of 4.3 is coming soon but you do have the choice to opt-in early for the preview. Just remember that just because you opt-in you can still open projects in 4.2.1 by just either opening the projects from your library or opening the 4.2.1 engine. All you would need to watch out for is opening the project with 4.3.0 and selecting Convert-in-Place, choose Copy instead so you have a unmodified project.

Thank You
