Vitest 4 to 5

Every Vitest 5.x release the archive holds, 6 of them, starting at 5.0.0 and running to 5.0.5. 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.

The turn

The last 4.x release the archive holds before the turn is 4.1.11, on 18 Aug 2026. 5.0.0 followed 16 days later. 4.x did not stop there. 1 more 4.x release shipped after 5.0.0 opened, the last of them on 15 Oct 2026, so both lines were being maintained at once.

Tagged breaking

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.
