Chrome 63 hit the Beta channel at the end of October, and it promised some significant changes for developers, including a new Device Memory API, async iterators and generators, dynamic module imports, as well as various permissions UI changes. It also brought major Blink engine improvements and other bug fixes. The Blink web browser engine improvements implemented in Chrome 63 improves things like DOM, CSS, HTML, MediaStream, JavaScript, bindings, fonts, network, storage, and sensor. The update also redesigns the chrome://flags page and tweaks the permissions drop-down a bit for a better Google Chrome experience.
