According to Google, "on November 19, 2013 we will deploy a JavaScript wrapper that attempts to automagically turn remaining v2 maps into v3 maps. Though we expect this wrapper to work for most simple maps, we cannot guarantee that your maps will continue to function. We therefore highly recommend that you migrate to v3 before November 19" - - and "upgrading to v3 will require rewriting some of your code."
Has anyone looked at this & what it means?
