+
+  ```js

+  await page.click('role=button[name="log in"]')
+  ```
+
+  To use role selectors, make sure to pass `PLAYWRIGHT_EXPERIMENTAL_FEATURES=1` environment variable:
+
+  ```js
+  // playwright.config.js
+  process.env.PLAYWRIGHT_EXPERIMENTAL_FEATURES = '1';
+  module.exports = {
+    /* ... */
+  };
+  ```
+
+  Read more in [our documentation](./selectors#role-selector).
+- New `scale` option in [`method: Page.screenshot`] for smaller sized screenshots.
+- New `caret` option in [`method: Page.screenshot`] to control text caret. Defaults to `"hide"`.
+
+- New method `expect.poll` to wait for an arbitrary condition:
+
+  ```js
+  // Poll the method until it returns an expected result.
+  await expect.poll(async () => {
+    const response = await page.request.get('https://api.example.com');
+    return response.status();
+  }).toBe(200);
+  ```
+
+  `expect.poll` supports most synchronous matchers, like `.toBe()`, `.toContain()`, etc.
+  Read more in [our documentation](./test-assertions.md#polling).
+
+### Behavior Changes
+
+- ESM support when running TypeScript tests is now enabled by default. The `PLAYWRIGHT_EXPERIMENTAL_TS_ESM` env variable is
+  no longer required.
+- The `mcr.microsoft.com/playwright` docker image no longer contains Python. Please use `mcr.microsoft.com/playwright/python`
+  as a Playwright-ready docker image with pre-installed Python.
+- Playwright now supports large file uploads (100s of MBs) via [`method: Locator.setInputFiles`] API.
