Google is releasing a new version of Chrome to users this week, and it includes a number of new interesting features. The best addition is the ability to mute entire sites that autoplay videos. There are a number of sites on the web that have decided to annoy users by playing videos that follow you while you scroll a page with the sound on. Instead of frantically closing the tab (or muting it) and swearing at your monitor, you can now just simply right-click the offending tab and mute the entire site for good. This replaces the previous “mute tab” feature that was only temporary.

Google is also adding HDR support to Chrome 64 for Windows users, which will require a PC with the Fall Creators Update, a HDR compatible monitor and graphics card. This latest version of Chrome also protects Mac and Windows users against the Meltdown and Spectre vulnerabilities. Google is following other browsers by disabling the SharedArrayBuffer feature to mitigate against the attacks.
