The language has been stable for years and non-minor features always discussed upfront through several proposals. With that said, if you are interested on the work happening on types, I wrote recently about it here: https://elixir-lang.org/blog/2022/10/05/my-future-with-elixi...
This announcement is about a new project, which we are very excited about and working on for months. We hope to officially release it tomorrow (Thu UTC). We are dotting the "i"s and crossing the "t"s right now.
I was definitely not expecting this to make to the front page, I should perhaps be more careful the next time. :)
