Yarn out-of-date about jupyterlab-feedstock HOT 2 CLOSED

Is it causing a problem, or just complaining? I also hate that message, but it hasn't broken on me yet.

Some background:

Original instigator of the violence that is yarn in lab here (I'm like a bad penny).

We ship A The One Yarn as a monolith .js aliased as jlpm in lab because it's not sane to support the many possible versions and ways yarn/npm interact with node on non-node-people's environments. Unless there's a CVE, major performance improvement, or in-the-wild node incompatibility, we haven't been staying on the bleeding edge.

Next time we ship, which is presumably 1.0.0, we should squelch that error in our config file... and probably update, but I was kinda holding out for yarn 2.0 before making any noise to that regard... i've updated jupyterlab/jupyterlab#4705.

from jupyterlab-feedstock.

Thanks for filing this. We've now updated yarn (but we are still behind current yarn :(. Regardless, this issue belongs on the jlab repo.
