You will no longer receive a success notice for every crosspost you make by default; you'll only be notified in your Inbox if an attempt fails.

I noticed that one already... thank you so much! Before, I just completely ignored my Inbox. I even ignored the little (ever-increasing) three-digit number after the "Inbox" link in the bar at the top of my reading page, because the whole thing was so jam-packed with notices that basically said, "Yup, the Internet still works".

Only getting notices for failures makes so much more sense! Thanks again!
