Google Chrome 63 now lives in the Beta channel pocket, and it can be installed on Chrome OS, Linux, Android, Mac, and Windows operating systems. It promises big changes for developers, including dynamic module imports, a new Device Memory API, permissions UI changes, as well as async generators and iterators. Chrome 63 Beta also comes with a bunch of improvements for the Blink web browser engine developed as part of the Chromium project, improving things like CSS, bindings, DOM, network, sensor, storage, JavaScript (JS), MediaStream, HTML, and fonts. These under-the-hood changes are important for the overall reliability of Chrome.
