+## Versioning
+
+Dapr has 2 versions of the Azure Blob Storage state store component: `v1` and `v2`. It is recommended to use `v2` for all new applications. `v1` is considered legacy and is preserved for compatibility with existing applications only.
+
+In `v1`, a longstanding implementation issue was identified, where the [key prefix]({{< ref howto-share-state.md >}}) was incorrectly stripped by the component, essentially behaving as if `keyPrefix` was always set to `none`.  
+The updated `v2` of the component fixes the incorrect behavior and makes the state store correctly respect the `keyPrefix` property.
+
+While `v1` and `v2` have the same metadata fields, they are otherwise incompatible, with no automatic data migration path for `v1` to `v2`.
+
+If you are using `v1` of this component, you should continue to use `v1` until you create a new state store.
