-For enterprise customers, HashiCorp provides official support for Consul and Vault's Integrated Storage as storage backends. Vault Enterprise will
-no longer startup if configured to use a storage backend other than Consul or Integrated Storage. This is meant to protect against issues caused by using

+For enterprise customers, HashiCorp provides official support for Vault's Integrated Storage and Consul as storage backends. Vault Enterprise customers are strongly
+recommended to use these supported storage backends for best outcomes. Version 1.12.0 of Vault Enterprise will not start if configured to use a storage backend
+other than Integrated Storage or Consul. This was meant to protect against issues caused by using unsupported backends that do not support transactional storage.
+Version 1.12.2 modified this behavior to instead log a warning when unsupported storage backends are used, while ensuring that Vault will start.
