foobar2000 Audioscrobbler plugin

It seems Last.fm have changed their API somewhere around March and this is what the console log says:

Audioscrobbler: Handshake successful.
Audioscrobbler: Submitting 10 of 359 cached tracks...
Audioscrobbler: Submission failed: Plugin bug: Not all request variables are set - got 90 parameters.

Do you plan to update it someday (or release the source code)? I really prefer this plugin over everything else…
