Does anyone know what these new targeting changes are? "Target by Saved Group". How does that work? Docs show old ui: https://docs.growthbook.io/features/rules#forced-value

This just launched last week and we haven't updated the docs yet. Sorry about that! The new UI is just a simpler way to add targeting based on Saved Groups. You can continue using attribute targeting just like before. If you specify both, they will be ANDed together to produce the final condition that is sent down to the SDK

Oh there's changes to Saved groups generally..

Saved Groups

Reusable groups of users you can target from any feature flag rule or experiment. There are two ways to define Saved Groups - Inline or at Runtime.
