Playwright v0.16.0 — Release Notes & Engineering Impact

## Browser Versions - Chromium 84.0.4131.0 - Mozilla Firefox 76.0b5 - WebKit 13.0.4 ## Highlights - Playwright now uses a single location on your machine to install all browsers. See [documentation](https://github.com/microsoft/playwright/blob/v0.16.0/docs/installation.md) for details. ## Breaking API Changes - Method [`page.waitFor`](https://github.com/microsoft/playwright/blob/v0.15.0/docs/api.md#pagewaitforselectororfunctionortimeout-options-arg) is removed. Use explicitly named methods such as [`page.waitForSelector`](https://github.com/microsoft/playwright/blob/v0.16.0/docs/api.md#pageselector), [`page.waitForFunction`](https://github.com/microsoft/playwright/blob/v0.16.0/docs/api.md#pagewaitforfunctionpagefunction-arg-options) and [`page.waitForTimeout`](https://github.com/microsoft/playwright/blob/v0.16.0/docs/api.md#pagewaitfortimeouttimeout). - The `'mutation'` polling option for methods like [`page.waitForSelector`](https://github.com/microsoft/playwright/blob/v0.16.0/docs/api.md#pageselector) is removed since it didn't work properly with Shadow DOM. ## New APIs - [`page.waitForTimeout`](https://github.com/microsoft/playwright/blob/v0.16.0/docs/api.md#pagewaitfortimeouttimeout) ## Resolved Issues #1810 - Improved docs #1867 - How to close the browser in case of an error (click element not found.) #1946 - [REGRESSION]: Lots of Navigation timeout errors in 0.14.0 #1950 - [BUG] Logger sink with name `browser` skips `browser:err` #1962 - [BUG] 0.15 Cannot launch new chromium context after closing old one #1968 - [REGRESSION]: Out of memory errors on 0.15.0 #1973 - [Question] Playwright-Docker help needed #1977 - What's the actual danger with --no-sandbox and --disable-setuid-sandbox #1981 - [Question] Documentation for page.waitForSelector() and visibility #1982 - [BUG] Documentation in regards to text selector engine and single and double quotes #1983 - [Feature] Add 'attribute' selector to the list of id, data-testid, ... #1986 - [Question] Alpine Linux Support #1987 - [BUG] A page.click() that initiates a navigation requires a waitFor() before a page.goto() #1988 - [BUG] Browsers not installing on Node 14 #1992 - [BUG] install fail #1993 - [Feature] waitFor() with string for selectorOrFunctionOrTimeout - return of JSHandle or ElementHandle #1996 - [BUG] CSS attribute selector not working with a value with spaces #2003 - [BUG] Problem resubmitting form in headful chromium #2012 - [Feature] page.$ and page.$$ should pierce shadow DOM #2024 - [Question] Issue with selecting text on the DOM #2025 - [Question] different behavior in headful and headless mode?
