2/14/2014 Update:  If you have more than one form defined, do not use beta-5, there is a serious bug which corrupts the content of the defined forms so they all contain the same data.

Beta #5 of Google Forms v0.64 is now available for testing.  This update addresses a plugin conflict between Google Forms and WordPress SEO plugin by Yoast.  The new implementation removes the hook into the_content which is a much more robust solution.
