Chrome 45 Developer Features of Note

With over 1 billion users, Chrome is the platform that developers must pay the most attention to when it comes to optimizing how their applications are being used by end-users and how they perform in general.

This week Google launched a new version of Chrome (v45) for Windows, Mac, Linux and Android and it will force a significant shift in how content is being served. Chrome now automatically pauses "less-imporant" Flash content (a feature that is being gradually introduced) that isn't "central to the Web page" while keeping the primary content playing without interruption. For example, a video currently being watched will be unaffected, while animations in a sidebar will be paused (anything Chrome pauses can be resume by just clicking on it). The goal, according to the company, is to increase page-load speed and reduce power consumption.

Chrome has also gained new JavaScript features (specifically, developers can now use arrow functions and new array methods), and implemented Subresource Integrity to help mitigate the risk of a compromised server and make sure only the expected resource is used (as opposed to any resource at a given URL).
