What's New

Version 3.1.0:
  • Using a new font for Japanese. It’s clearer, more legible, and goes well with aubergine. (Which is the default color of your sidebar. As well as a vegetable.)
  • Sometimes Slack takes too long to start up. If that happens, a) we’re sorry that it does, but b) you’ll now see a link with some helpful troubleshooting ideas.
  • When a file’s done


  • OS X 10.9 or later
