We've upgraded the Puppeteer library for our browser checks from v1.19 to v2.0.0, a stable release with 73 new features and enhancements, including an updated Chromium version to 79.0.3942.0, NodeJS version 10, and new APIs such as page.screenshot and page.emulateMediaType. The upgrade also includes bug fixes like clipping elements to the viewport in page.screenshot and removing the deprecated page.emulateMedia API.
