Vitest 4 to 5
Every Vitest 5.x release the archive holds, 5 of them, starting at 5.0.0 and running to 5.0.4. The publisher writes these one at a time and its documentation describes the version you are on, so the run between two majors is not laid out anywhere as a list.

1 of these releases carries the breaking label: 5.0.0. The label is matched from words in the publisher’s own notes, so a release that changed an API without using the word does not carry it.
