Phoenix does not support poison 3.0

Hi all
I want to use the poison 3.0 on my phoenix app based on version 1.2.1 and added to mix.exs.
When I want to get the dependency with mix deps.update then it shows me:

Failed to use "poison" (version 3.0.0) because
  phoenix (version 1.2.1) requires ~> 1.5 or ~> 2.0
  mix.exs specifies ~> 3.0

How to make phoenix compatible to poison 3.0?

Thanks

Hmm, could override it, but that still leaves a question of if phoenix would work. Do you know what changes were made from Poison 2 -> 3?

Not at all. I do not know, if there a big changes or not.

Hmm, they don’t have a changelog or describe the changes in the readme or so, unsure myself… Try overriding it and see if anything breaks?

{:poison, "~> 3.0", override: true} # Something like this?

Yes, it accepted. Now I have to test, if it works or not.

Thanks so much.

Yes, the changes in Poison 3.0 did not affect Phoenix. Phoenix master also supports Poison 3.0, here is the commit: https://github.com/phoenixframework/phoenix/commit/655f45bf9cf6cc0b1d85af3d1c9c43afbcacaf1a
