`jsonschema` & `beat-devel` version conflicts

I might have figured out the CI issues...specifying the new jsonschema version requirement in conda/meta.yaml conflicts with beat-devel:

UnsatisfiableError: The following specifications were found to be in conflict:
  - beat-devel=2019.04.30 -> jsonschema==2.6.0=py36h006f8b5_0
  - jsonschema[version='>=3.0.0']

Do we need to restrict jsonschema to 2.6.0 in beat-devel, or can we bump it to 3.x?
