Version 2.0.7 Released June 26, 2011, still in sandbox. Why? Rated 4 out of 5 stars

Version 2.0.7 Released June 26, 2011, is still in sandbox.
1- Why, please?
2- Which to choose, 2.0.6 or 2.0.7 ? I think this is the first time I observe a 17 months' sandbox closet.
Before installing, I'll rate this add-on with a neutral+1 : 4 stars.
