ipykernel 6.0 release planning

[SylvainCorlay]

IPykernel 6.0 will be a major release (debugger support, tornado coroutines removed, and more).
We have tagged a few pre-releases, but I think we should try to identify things that we want to resolve for 6.0:

• issues introduced by the latest changes,
• outstanding bugs that should be fixed in this milestone,
• deprecated APIs and major changes we want to remove completely in this occasion.

As far as I can tell the few left issues are fixed, or can be postpone, and we had no issues reported in the last two weeks, do you believe it is time for a release ?

[Carreau]

There was only one PR in the last 2 weeks, any thoughts on making a RC ? @blink1073 I think you are the one who usually releases?

RC sounds good, will cut one today

I've tagged all merged PRs and closed issue of the past ~1 year with the correct milestone and sent a PR to upddate the changelog.

Sorry for showing up late here. I ran our kernel test suite with ipykernel 6 and everything seems to be working fine: spyder-ide/spyder-kernels#292

What's the plan for the final release? I'm asking because we have a bunch of other tests in Spyder itself and I'd like to run them too. So if you could give me until this weekend, it'd be great.

So if you could give me until this weekend, it'd be great.

No problem! I'll be OOO Friday-Monday, so Tuesday is the earliest I would release anyway.

[ccordoba12]

Great! I'll report back with new results then during the weekend.

[Carreau]

I've cleaned up a bunch of deprecation in the last week, so we can also do a last RC just in case if there are any concerns.

[blink1073]

Yeah, that makes sense to me, I'll cut another RC today.
