Timeline for Losing Workspace Features with Dovetail 3.0 Rollout

We’re on the legacy plan and it’s not up for renewal until April 2025 (we’ll be switching to the professional plan). My question is: when are we losing workspace fields, workspace templates, and the ability to customize our homepage? When Dovetail 3.0 is rolled out on December 12th, or when we renew/move to the professional plan in April?
