First blog about test classloading changes

[holly-cummins]

I've added a blog discussing the externals of the test classloading change.

I was also hoping to discuss the internals, but that's harder so I kept putting it off. We ought to publish something alongside 3.22, so I've run out of runway to write an epic blog. The discussion of internals should maybe be in its own blog, which gives more time to get "part ii - the terrifying internals" written and out.

🙈 The PR is closed and the preview is expired.

really good write up - added a few clarifying suggestions but good stuff!

[cescoffier]

Looks great! I added a few comments, nothing serious.

[holly-cummins]

I think I've done all your suggestions, @cescoffier, except the rework of that introductory paragraph, where I can't come up with something that flows well. I didn't do an admonition for augmentation, just a link, because I didn't want to interrupt the bulleted flow.

Here it is with the admonition, but I think it distracts from the more important content. WDYT, @cescoffier?

[cescoffier]

Agreed, the admonition is too prominent. It's where I would love to have "side notes" - link it is.

[maxandersen]

mark as approved based on the issues i commented on is fixed. let you decide when to merge after admonition fixed.

[holly-cummins]

I've removed the admonition and squashed. I don't know if it's best to put this out to coincide with 3.22 (yesterday) or 3.22 platform (next week).

[cescoffier]

Great!

I would postpone the publication after the 3.22 platform release announcement, maybe just after it. But, no strong opinion.

[holly-cummins]

I've adjusted the date and squashed, so we should be good to merge tomorrow. I've had one zulip message reporting the dev services startup sequence change already, so we should not delay past tomorrow, I think.
