I will second this. I've been using multiple libraries in our production Elixir app that haven't been updated in the last five years. Elixir itself was declared as "stable" feature-wise years ago. It may be argued that the type system being introduced is not in-keeping with that, but not sure. Jose is a very cautious and diligent "benevolent dictator" and you get a lot of backward compatibility guarantees. Erlang is the same. Compared to what some people might be used to with churn in Node/React etc it is apples and oranges.
