Release 2022.6.0

[jrbourbeau]

Given the 2022.05.2 patch release last Thursday, I'll propose we push our normal two week release cadence back one week and have our next release on June 10. Opening up a tracking issue early than usual to give ample notice

Release version	2022.6.0
Planned release date	2022-06-10

Release manager	@jrbourbeau

@fjetter should I put dask/distributed#6480 down as a blocker?

Not Florian, but given this is done maybe it is worth noting it is at least complete

Now that we've done the rebrand of Dask the latest docs are using the new theme and logo. The stable docs will continue to use the old theme and logo until the next release, so it would be great to get this out as soon as we can.

[jrbourbeau]

We can also just manually trigger a new stable docs build if we want to get the new theme out ASAP. That should build the docs from the same commit as the previous release, but should pull in the new theme

[jacobtomlinson]

Ooh good point. That would be great. Do you mind handling that @jrbourbeau ?

[jrbourbeau]

https://docs.dask.org/en/stable/ and https://distributed.dask.org/en/stable/ have both been rebuilt and are using the new theme now 👍

Just wanted to check in here to see if folks have any known blockers we should be aware of before releasing this Friday.

In an offline conversation earlier today, @crusaderky mentioned that the worker state machine refactor (xref dask/distributed#6476) is getting close and some substantial PRs related to this effort are about to land in distributed. Because of this, I proposed we hold off on merging those PRs until after releasing on Friday to give those changes time to simmer in main. @crusaderky was okay with this and didn't think it would slow down development meaningfully.

@crusaderky I've added the remaining PRs that link to dask/distributed#6476 to a new "Merge after releasing" section at the top of this issue. Let me know if that looks good, or if there are any adjustments I should make

Blocker: dask/distributed#6528

[jacobtomlinson]

This probably isn't a huge issue but all NVIDIA staff are OOTO thu/fri this week. So if there are last-minute release issues fewer folks will be around.

[jrbourbeau]

Just following up here. All reported blockers have been resolved so, unless a new blocker pop up, I'll push out the 2022.6.0 release tomorrow

[jakirkham]

Think we may want to get PR ( dask/distributed#6557 ) in
