How many Mr. Robot episodes have there been this season (no spoilers)

It was my understanding that there have been only three (7/13, 7/20, and 7/27), but it looks like there was a thread discussing episode 4. Also, on a previous thread it appeared to me you guys were discussing episode 2 before the air date of 7/20. I bailed before I could confirm, because I didn't want to get spoiled.

Have I miscounted? I know they released episode 1 on USA on demand or whatever before it originally aired. Have they continued releasing an episode before the air date? I want to jump in the discussion, but want to avoid getting spoiled in the process. I thank you your time.
