 Although you cannot version a process application itself, you can use [bulk version creation](versions.md#bulk-version-creation) and version tags to save a single snapshot of all the process application files in one action, instead of having to create separate versions for every file.
 
 - When you create a version in any process application file, a version is also created with the same name (version tag) for all files currently available in the process application.

 You can create a version at any time to save a snapshot of your BPMN or DMN diagram.
 
 You can restore a version to revert to a previous snapshot of your diagram, for example if you make a mistake while modeling. You can also compare two versions to see the differences between them.

+### Milestones renamed to versions {#web-modeler-milestones-renamed-to-versions}
+
+The term "milestones" has been renamed to ["versions"](/components/modeler/web-modeler/versions.md) in Web Modeler for clarity and consistency with other Camunda 8 components. The renaming is implemented across the Web Modeler user interface and the API.
+
+In [the API](/apis-tools/web-modeler-api/index.md), new endpoints starting with `/api/v1/versions` have been introduced, while the previous `/api/v1/milestones` endpoints are now deprecated.
+Further details can be found in [Web Modeler's OpenAPI documentation](https://modeler.camunda.io/swagger-ui/index.html).
+
+:::note
+This is a nominal update and the functionality of versions and milestones is equivalent.
