+## Version 1.12
+
+#### ⚡️ Introducing Playwright TestRunner
+
+[Playwright TestRunner](./test-intro.md) is a **new test runner** built from scratch by Playwright team specifically to accommodate end-to-end testing needs:
+
+- Run tests across all browsers.
+- Execute tests in parallel.
+- Enjoy context isolation and sensible defaults out of the box.
+- Capture videos, screenshots and other artifacts on failure.
+- Integrate your POMs as extensible fixtures.
+
+Installation:
+```bash
+npm i -D @playwright/test
+```
+
+Simple test `tests/foo.spec.ts`:
+
+```ts
+import { test, expect } from '@playwright/test';
+
+test('basic test', async ({ page }) => {
+  await page.goto('https://playwright.dev/');
+  const name = await page.innerText('.navbar__title');
+  expect(name).toBe('Playwright');
+});
+```
+
+Running:
+
+```bash
+npx playwright test -c tests
+```
+

+
+#### 🧟‍♂️ Introducing Playwright Trace Viewer
+
+[Playwright Trace Viewer](./trace-viewer.md) is a new GUI tool that helps exploring recorded Playwright traces after the script ran. Playwright traces let you examine:
+- page DOM before and after each Playwright action
+- page rendering before and after each Playwright action
+- browser network during script execution
+
+Traces are recorded using the new [`property: BrowserContext.tracing`] API:
+
+```ts
+const browser = await chromium.launch();
+const context = await browser.newContext();
+
+// Start tracing before creating / navigating a page.
+await context.tracing.start({ screenshots: true, snapshots: true });
+
+const page = await context.newPage();
+await page.goto('https://playwright.dev');
+
+// Stop tracing and export it into a zip archive.
+await context.tracing.stop({ path: 'trace.zip' });
+```
+
+Traces are examined later with the Playwright CLI:
+
+
+```sh
+npx playwright show-trace trace.zip
+```
+
+That will open the following GUI:
