Breaking changes have had that tag for ages

Really? Retired? What does that even mean in this context, why not "breaking" or something else that suggests breaking change?

> Retired? What does that even mean in this context

"retired" is probably a followup to functionality that was "deprecated".

I agree "breaking" would be clearer

What exactly is it that's now retired that used to be deprecated? Isn't this just a collection of breaking changes to defaults?

if you go to the full changelog on the blog and click on the "retired" button, the url will have type=deprecations as the parameter.

It's a holdover from previous posts where there were more clearly defined deprecations.

but yes, in this case it's more of a behavioural change of defaults, so they just picked the closest vaguely mapped retired/deprecations tag.
