[wobsoriano]

new two-parameter Assertion interface for custom matcher augmentations https://vitest.dev/guide/migration/#assertion-types-expose-return-and-received-types

[wobsoriano]

global assignments in DOM environments now propagate to the window https://vitest.dev/guide/migration/#dom-environment-global-assignments-now-update-the-underlying-window

this is the documented way to override globals
