I've just checked out a #Clojure project I last worked on thirteen years ago, compiled it, ran its unit tests, and they all passed. I then ran `lein ancient upgrade :check-clojure` to upgrade all the dependencies to their latest versions, ran the unit tests again, and they all passed.

I did get one 'deprecated' warning. I can live with that!

It's not stability that I came to Clojure for, but it's a feature I really appreciate.

Say 'no' to bit rot!
