## Breaking Changes & Required Actions
- [BREAKING] ⚠️ Playwright no longer tests on Node.js 20. Use Node.js 22, 24 or 26, as listed in the system requirements.
- There is no watch mode. UI mode does not run tests again when files change, and `--only-changed` does not follow imports.
- Bun loads modules itself, so `--tsconfig` and the JSX options in `tsconfig.json` have no effect, and custom ESM loaders are not supported.
- Stack traces do not include async frames, and API names do not include the class name: `click` instead of `locator.click`. This changes some step locations, step titles and erro...
- Console output of a test does not get into the trace and UI mode.
