alex added a mute notifications option for recs/asks if the comments, likes, etc, are getting a bit out of hand in your inbox. It's live on the site and app.
I know a lot of you have accidentally blocked people (or changed your mind) so mitchgruen added a "manage blocks" page within your settings. It's only on the website right now, but it'll be on the app soon.
We also launched a better Weekly Digest email that drops every Friday.
Fixed a lot of bugs and made it easier to consistently ship changes to the mobile app without it crashing for you guys.
I'm also working on some other cool stuff that'll be revealed in time...
