Hi!
I am currently working on a project running Phoenix v1.4 and Elixir v1.9 and planning to update Elixir version to 1.11, at the beginning I was planning to update Phoenix version as well but because of some reasons I would like to postpone Phoenix update if possible, so my question is: Is Phoenix v1.4 compatible with Elixir v1.11? I couldn’t find any information about this.
Thanks!

Elixir 1.X series should not break backward compatibility: and legal code that ran on older 1.x shall run unmodified on later 1.y. If not, it is a bug on Elixir.
