Well it doesn't look like the 2012 version of the plugin is available. At least I haven't been able to find it. The link for the provider is here if you wish to use the one from last year in the meantime or maybe wait for it to get updated.

If anybody has a link to an updated version, please shoot it this way; I'm in the same boat.
