Hi,
Here's a typical definition of a contribution to the versioning service that controls available options:
<extension target="org.nuxeo.ecm.core.versioning.VersioningService" point="versioningRules">
<versioningRule typeName="MyDoc">
<initialState major="0" minor="0"/>
<options lifeCycleState="*">
<none default="true"/>
<minor/>
<major/>
</options>
</versioningRule>
</extension>
You can define your own for your document type, and remove the "none" option if you'd like to force version increment.
This cannot be used in an XML extension in Studio waiting for https://jira.nuxeo.com/browse/NXS-1259 issue to be fixed, but as a workaround, you can put this contribution in a another jar and make it require the Studio bundle (to make sure it's deployed afterwards).
