Business Central 2026 Release Wave 2 (v29.0) Is Generally Available

Version 29.0 of Business Central is now generally available for new online environments. Preview sandboxes created before GA will be automatically deleted in early November 2026, so users with test data or custom extensions need to export and migrate to the GA build immediately.

Key points

Version 29.0 is the default option for new online environments created today
Preview sandboxes from September have about 30 days before automatic deletion
Preview environments cannot be updated to a different version, requiring export and recreation
Users must migrate test data and custom extensions to the GA build before the early November cutoff
