With the Chromium 50 and Opera 37 release, Regular Expressions can now handle Unicode better,
<link rel="preload" as="…"> is supported, CSS
column-fill can balance multi-column layout content better, and Geolocation and App Cache API won’t work on non-HTTPS contexts anymore, and
Object.observe won’t work anymore as well.
