Yammer App for SharePoint – unsupported version

If you are using the Yammer app for SharePoint, or if you are using the Yammer embed code on your site, you might get the following error message:

“This page or app is using an unsupported version of the Yammer platform”

It seems that Yammer recently updated their API. You need to update the SharePoint App to get rid of the error message. More instructions in this knowledge base article: http://support.microsoft.com/kb/2966312
