This is probably the thread you’re referencing @JCPalmer ?
Current “release date” for 5.0 is April 28th 2022. That’s when we’ll move the preview build of 5.0 to the stable build.
That said, we’re shipping 5.0 to preview every week, actually more like every day. 
It’s a goal of the dev team to ensure that the preview build of Babylon is cutting edge, but also bug free and reliable. Most developers who use Babylon, actually point to preview because of our obsession with ensuring quality and backwards compatibility in every release.
Hope this helps!
