### Highlights
* UI mode is now available in VSCode Playwright extension via a new "Show trace viewer" button:
* UI mode and trace viewer mark network requests handled with [`page.route()`](https://playwright.dev/docs/api/class-page#page-route) and [`browserContext.route()`](https://playwright.dev/docs/api/class-browsercontext#browser-context-route) handlers, as well as those issued via the [API testing](https://playwright.dev/docs/api-testing):
* New option `maskColor` for methods [`page.screenshot()`](https://playwright.dev/docs/api/class-page#page-screenshot), [`locator.screenshot()`](https://playwright.dev/docs/api/class-locator#locator-screenshot), [`expect(page).toHaveScreenshot()`](https://playwright.dev/docs/api/class-pageassertions#page-assertions-to-have-screenshot-1) and [`expect(locator).toHaveScreenshot()`](https://playwright.dev/docs/api/class-locatorassertions#locator-assertions-to-have-screenshot-1) to change default masking color:
```js
await page.goto('https://playwright.dev');
await expect(page).toHaveScreenshot({
mask: [page.locator('img')],
maskColor: '#00FF00', // green
});
```
* New `uninstall` CLI command to uninstall browser binaries:
```bash
$ npx playwright uninstall # remove browsers installed by this installation
$ npx playwright uninstall --all # remove all ever-install Playwright browsers
```
* Both UI mode and trace viewer now could be opened in a browser tab:
```bash
$ npx playwright test --ui-port 0 # open UI mode in a tab on a random port
$ npx playwright show-trace --port 0 # open trace viewer in tab on a random port
```
### ⚠️ Breaking changes
* `playwright-core` binary got renamed from `playwright` to `playwright-core`. So if you use `playwright-core` CLI, make sure to update the name:

```
This change **does not** affect `@playwright/test` and `playwright` package users.
