CSS ● Implemented the allow-end value of the hanging-punctuation CSS property ● Improved web compatibility by resetting CSS spacing rules on ● Added the new color-gamut CSS media query ● Updated screen queries to check the capabilities of the current screen instead of the deepest available screen
Web APIs ● Restricted WebSockets header parsing according to RFC6455 and RFC7230 ● Improved performance of certain draw calls in WebGL with a non-power-of-two texture optimization ● Disabled the Fetch API until the implementation is ready to be enabled by default ● Enhanced Shadow DOM support to compute styles for the style attribute of elements ● Softened pushState and replaceState frequency restrictions
