Dynamics 365 Business Central license keys: what changes from version 28.
Starting October 1, 2026, Dynamics 365 Business Central on-premises and Dual Use Rights licenses no longer use version-specific keys. Instead, a single '28+' key family applies to all versions 28 and later, requiring administrators to download a refreshed license file before each version upgrade to unlock new objects.
