graphql-core v3?

[GinTR1k]

Hello!

Is there any plan to update graphql-core dependency to the latest version?

[hyusetiawan]

would love to know about this as well

Hey there, to add some context here - graphql-ws is now incompatible with graphql-core included in graphene and graphql-server. I've discussed this a bit over here: https://app.slack.com/client/TBFTZEULB/CBG1GAB42/thread/CBG1GAB42-1605717933.051400

Attempting to install the following packages:

graphene = "==3.0.0b2"
graphql-server = {extras = ["aiohttp"], version = "==3.0.0b2"}
graphql-ws = "==0.3.1"

Results in:

pipenv install graphql-ws==0.3.1

  First try clearing your dependency cache with $ pipenv lock --clear, then try the original command again.
 Alternatively, you can use $ pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.
  Hint: try $ pipenv lock --pre if it is a pre-release dependency.

There are incompatible versions in the resolved dependencies:

  graphql-core<4,>=3.1.0b1 (from graphene==3.0.0b2->-r /tmp/pipenvam0pkvu9requirements/pipenv-d_a7l2a7-constraints.txt (line 2))

fwiw, using pip instead of pipenv results in graphql-ws installing but it is then incompatible at the code-API layer:
