+## Project/Workspace Options Scoped per Command
+
+In previous versions, the options `--config` / `-c`, `--dependency-definition`, `--workspace-config`, and `--workspace` / `-w` were accepted by every UI5 CLI command. Several commands silently ignored them.
+
+With UI5 CLI v5, these options are now only accepted by commands that actually consume them. Passing them to other commands now fails with `Unknown argument: <option>`.
+
+| Command                       | `--config` / `--dependency-definition` | `--workspace` / `--workspace-config` |

 ## UI5 CLI Init Command
 
 The `ui5 init` command now generates projects with Specification Version 5.0 by default.
