We rewrote our Getting Started docs to be more end-to-end testing focused. Check them out on [playwright.dev](https://playwright.dev/python/docs/intro).
Use the new methods [`method: Page.routeFromHAR`] or [`method: BrowserContext.routeFromHAR`] to serve matching responses from the [HAR](http://www.softwareishard.com/blog/har-12-spec/) file:
```python async
await context.route_from_har("github.har.zip")
```
```python sync
context.route_from_har("github.har.zip")
```
Read more in [our documentation](./network#record-and-replay-requests).
### Advanced Routing
You can now use [`method: Route.fallback`] to defer routing to other handlers.
Note that the new methods [`method: Page.routeFromHAR`] and [`method: BrowserContext.routeFromHAR`] also participate in routing and could be deferred to.
### Web-First Assertions Update
* New method [`method: LocatorAssertions.toHaveValues`] that asserts all selected values of `<select multiple>` element.
* Methods [`method: LocatorAssertions.toContainText`] and [`method: LocatorAssertions.toHaveText`] now accept `ignore_case` option.
### Miscellaneous
* If there's a service worker that's in your way, you can now easily disable it with a new context option `service_workers`:
- Role selectors that allow selecting elements by their [ARIA role](https://www.w3.org/TR/wai-aria-1.2/#roles), [ARIA attributes](https://www.w3.org/TR/wai-aria-1.2/#aria-attributes) and [accessible name](https://w3c.github.io/accname/#dfn-accessible-name).
- New role selectors that allow selecting elements by their [ARIA role](https://www.w3.org/TR/wai-aria-1.2/#roles), [ARIA attributes](https://www.w3.org/TR/wai-aria-1.2/#aria-attributes) and [accessible name](https://w3c.github.io/accname/#dfn-accessible-name).
Playwright 1.17 introduces [frame locators](./api/class-framelocator) - a locator to the iframe on the page. Frame locators capture the logic sufficient to retrieve the `iframe` and then locate elements in that iframe. Frame locators are strict by default, will wait for `iframe` to appear and can be used in Web-First assertions.
Read more at [our documentation](./api/class-framelocator).
### Trace Viewer Update
Playwright Trace Viewer is now **available online** at https://trace.playwright.dev! Just drag-and-drop your `trace.zip` file to inspect its contents.
> **NOTE**: trace files are not uploaded anywhere; [trace.playwright.dev](https://trace.playwright.dev) is a [progressive web application](https://web.dev/progressive-web-apps/) that processes traces locally.
- Playwright Test traces now include sources by default (these could be turned off with tracing option)
Its now possible to emulate the `forced-colors` CSS media feature by passing it in the [context options](https://playwright.dev/python/docs/api/class-browser#browser-new-context-option-forced-colors) or calling [Page.emulate_media()](https://playwright.dev/python/docs/api/class-page#page-emulate-media).
### New APIs
- [Page.route()](https://playwright.dev/python/docs/api/class-page#page-route) accepts new `times` option to specify how many times this route should be matched.
- [Page.set_checked(selector: str, checked: bool)](https://playwright.dev/python/docs/api/class-page#page-set-checked) and [Locator.set_checked(selector: str, checked: bool)](https://playwright.dev/python/docs/api/class-locator#locator-set-checked) was introduced to set the checked state of a checkbox.
- [Request.sizes()](https://playwright.dev/python/docs/api/class-request#request-sizes) Returns resource size information for given http request.
- [BrowserContext.tracing.start_chunk()](https://playwright.dev/python/docs/api/class-tracing#tracing-start-chunk) - Start a new trace chunk.
- [BrowserContext.tracing.stop_chunk()](https://playwright.dev/python/docs/api/class-tracing#tracing-stop-chunk) - Stops a new trace chunk.
The difference between the [Locator](./api/class-locator) and [ElementHandle](./api/class-elementhandle) is that the latter points to a particular element, while [Locator](./api/class-locator) captures the logic of how to retrieve that element.
React and Vue selectors allow selecting elements by its component name and/or property values. The syntax is very similar to [attribute selectors](https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors) and supports all attribute selector operators.
- [`nth`](./selectors#n-th-element-selector) selector engine is equivalent to the `:nth-match` pseudo class, but could be combined with other selector engines.
- [`visible`](./selectors#selecting-visible-elements) selector engine is equivalent to the `:visible` pseudo class, but could be combined with other selector engines.
[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:

- support for **async predicates** across the API in methods such as [`method: Page.waitForRequest`] and others
- [Playwright for Java v1.10](https://github.com/microsoft/playwright-java) is **now stable**!
- Run Playwright against **Google Chrome** and **Microsoft Edge** stable channels with the [new channels API](./browsers).
