ipyparallel for ipykernel -- deprecated or what?

There are a few files in the source tree where importing them triggers a warning they're deprecated and one should use ipyparallel.

But ipyparallel is mentioned as a test dep in setup.py, and not as a dep in pyproject.toml.

And CHANGELOG.md and a few but reports here mention ipyparallel itself as being deprecated.

What is the status of ipyparallel in ipykernel?

Hi @SnarkBoojum, ipyparallel is an optional dependency, but we do use it in our tests. The PR that you mention in the CHANGELOG is a confusing name, what it actually is doing is removing a deprecated function and test that moved to ipyparallel.

ipyparallel isn't deprecated, but some functionality specific to ipyparallel used to live in ipykernel. That's been moved to the ipyparallel package, and the old implementations of ipyparallel-specific functionality in ipykernel were deprecated.
