So that I understand this properly: we fixed a problem where no errors were reported - but the examples were wrong? So users might see errors without changing their API description, is that correct? Was it specifically when the changes went across files?

So users might see errors without changing their API description, is that correct?

Actually vice versa. We show an error when there's no error (due to wrong references caching). After the update, false errors should be gone.

OK let's update the changelog entry to describe what the user might experience.

I checked the ajv code and our code again.

This looks like it should not break anything! 🎉

Let's merge.

Really happy to get this sorted out. Thanks!
