Our Commentary ​

Vitest just keeps getting better, doesn't it? The --last-failed and --since-last-run flags are absolute game-changers for iterative development. I'm also really excited about the interactive snapshot review; that's going to save so much time. It feels like they're really listening to what developers need for a smoother, faster testing workflow. This release is packed.
