 # Prefect Release Notes
 
+## Release 2.16.9
+
+### `prefect deploy` with `-jv/--job-variable` option
+
+In a prior release, we added a `-jv/--job-variable` option for providing job variables when running a deployment using `prefect deployment run`. We want to be consistent in our CLI by allowing you to use this option while creating deployments during `prefect deploy`! Thus, we have added a `-jv/--job-variable` option to `prefect deploy` to replace the `-v/--variables` option, which we have now deprecated.
+
+See the following pull request for implementation details:
