Asset publishers configured to View in Context now append the most recent version number to web content urls. So, for example, what was formerly www.mysite.org/-/myarticle is now www.mysite.org/-/myarticle/1.2
For some reason, the inclusion of the version number causes the web content's display template not to render. If the version number is removed, the web content's display template runs and the content displays correctly.
Although the primary problem is that the web content template doesn't run when the version number is included in the url, having the version number in the url also seems very problematic for other reasons, such as search engine optimization and sharing links.
