The current version
of a model is the latest version in which the model properties and
file contents are editable. If you add a new model version manually
or perform an action that automatically creates a new model version
(such as setting it as the champion model or publishing a champion
model from the project level), a snapshot of the model’s contents
is taken and a version number is assigned. A new version is also created
when you update a model that is located within a folder. However,
the contents of the new model version that is created can no longer
be edited. You can only view the contents of the new model version.
Model versions cannot be deleted.
