The Additional Use Grant forbids offering Vault to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vault
Each version only converts to MPL 2.0 four years after that version is published, and the Change Date is tracked per version
Replication, HSM support, namespaces, performance standby nodes, FIPS builds, control group authorisation, multi-factor authentication, secrets sync and lease count quotas all require a Vault Enterprise licence
A Vault Enterprise licence must be applied to the cluster before any Enterprise feature can be used
