Microsoft just announced on August 25, 2026 that they are moving away from the traditional twice-a-year Release Wave model entirely. Going forward, Dynamics 365, Power Platform, and Dataverse features will be tracked through a continuous "AI at Work" roadmap instead. So Wave 2 2026 will essentially be the last traditional release wave announcement as we know it.
That said, Wave 2 2026 general availability is still rolling out from October 2026 as usual, with the detailed release plans expected to be published around mid-September. Early access in sandbox environments typically opens 4 to 6 weeks before the main launch, so that should be coming very soon if not already available.
For the most up to date info you can check the official release planner at aka.ms/releaseplans, and it's always worth enabling early access on a sandbox environment to start testing new features before they hit production.
