About Elixir-1.6.6 version on Erlang-Solutions repo

There is currently no upgrade for version 1.6.6, but the latest version of Erlang/OTP is already 21.0.

Is there a convenient way for me to get elixir-1.6.6.deb?

I’m not sure how often erlang solution rebuilds the packages.

Usually its fine to wait.

If you need 1.6.6 urgently, you can either build from source or use an environment manager like asdf.
