This release makes some significant changes to how tests are running. If you were using --no-threads before, you might consider enabling --single-thread instead (because your tests are now running in child_process instead of a worker thread) or try our new performance optimization feature (discussed later). If you were relying on API that was not available inside a worker (like process.chdir(), you can now use this option.
One of the potential breaking bug fixes is that environments do not share the same global scope anymore if you run them with --no-isolate, --no-threads or --single-thread - you might need to update your setup files if you were relying on a global variable before.
If you had performance issues on large code bases before, try the new deps.experimentalOptimizer option instead of disabling threads. Feedback is welcome!
One of the breaking changes includes adding a link to snapshots inside snapshot files, meaning you will need to update all your snapshots.
Tests with node and jsdom (and other environments) now don't share the same global scope, if you run them with --no-isolate or --no-threads flag. Vitest doesn't provide a way to restore the previous behavior as it is considered a bug.
