Thought I'd give a quick update on my personal contribution efforts, given I'm involved in so many different projects.

Metatag for Drupal 7

The Drupal 7 version of Metatag is pretty darned solid at this point. Some tests were added recently that will make sure the output works correctly for all tests, so the next release might be the last for a while. Speaking of which, I'm planning to do a bug fix release on December 31st.
