RLS: 0.20.3
@jreback @jorisvandenbossche 

Sorry, I was out the past few days and getting caught up on things. Did we want to do a 0.20.3 release soon? I thought it was for this week, but I see now that it's pushed to July 10th.

That's the week of Scipy, so I would probably do it the week before, which I guess is next week. Sound good?
