+- You can consider the client tools ([ScalarDL Client Command](./scalardl-command-reference.mdx) and [ScalarDL Schema Loader](./schema-loader.mdx)) to be the same as the ScalarDL Java Client SDK. In other words, you can apply the same compatibility rules to client tools as the ScalarDL Java Client SDK.
+- When you create a new deployment of ScalarDL, we recommend using the same version of ScalarDL Schema Loader as the version of ScalarDL.
+- When you upgrade the minor or patch version of ScalarDL, basically, you don't need to update the existing schemas. In other words, basically, you don't need to re-run ScalarDL Schema Loader when you upgrade a minor or patch version of ScalarDL.
+- If you use a new feature that ScalarDL provides in a new minor version, you may need to use the same or a later version of the client tools or re-create (or update) existing schemas. For details, please refer to the relevant documentation about each feature.

 ### Version skew policy
 
 - If the **major** versions are different between ScalarDL and the client SDK, they are **not** compatible and are **not** supported.
