Yahoo’s new Tumblr for iOS updated with “stacks” like post type chooser, app attribution

Tumblr, which was purchased by Yahoo today for a cool $1.1 billion, received an update for iPhone and iPad today that introduces a new post type chooser that resembles fan stacks on the dock in OS X but still includes a 17+ rating.┬áThe update also includes attributing app sources to posts shared on Tumblr.┬áThis update doesn’t seem to reflect any changes from Yahoo as the social blogging platform was just acquired this morning.
