1.) Use a 7.2 vanilla bundle with latest fix pack.
2.) Create a new page and add an Asset Publisher to it. In Asset Publisher --> Configuration --> Display Settings, here enable '
Set as the Default Asset Publisher for This Page'.
3.) Create a new article and set a display page created in step two and publish it twice to have two versions.
Result: Check the article in Asset Publisher, if you choose it and Asset Link Behavior --> View in Context is selected then the version number will be visible in the URL.
