 Shoulda Matchers provides RSpec- and Minitest-compatible one-liners that test
 common Rails functionality. These tests would otherwise be much longer, more
 complex, and error-prone.

+### This is the master branch
 
-### Note from the maintainer
+We are currently working on shoulda-matchers 4.0, which will support Ruby 2.4
+and Rails 5.x. We don't have a date on when this will be released, but you can
+stay up to date on the progress by monitoring [the milestone][4-0-milestone].
+Use this branch at your discretion!
 
-> Are you a fan of Shoulda Matchers? Are you interested in maintaining a popular
-> open-source project? If so, please contact me. Don't misunderstand me -- I
-> still use Shoulda Matchers on every project, but unfortunately, it has been a
-> long while since I've been able to give it the love it deserves, and I'd like
-> to hand the reins over to someone else who is able to do that. If you're
-> interested, I can be reached on Twitter as @mcmire or at
-> <elliot.winkler@gmail.com>. Thanks!
