Microsoft Edge Improvements in build 10532

Microsoft didn’t add much to improve user experience and extensions. Instead, they are focusing on HTML5 performances by adding new EdgeHTML and Chakra features along with build 10532, including:

New EdgeHTML features now available to preview:

  • Pointer Lock (Mouse Lock)
  • Extended srcset (sizes)
  • Canvas blending modes
  • oninvalid event handler
  • input type=time
  • input type=text selectionDirection

New Chakra features now available to preview:

  • asm.js now enabled by default (previously behind a flag)
  • ES2015 Classes now enabled by default (previously behind a flag)
  • ES2015 Destructuring now available behind the Experimental JavaScript features flag
  • ES2015 conformance updates
  • ES2016 Async Functions now available behind the Experimental JavaScript features flag

And according to HTML5Test, that puts Microsoft Edge to up pass 400 points and leaves both Internet Explorer 11 and Safari 9.0 behind its back. However, it’s still marginally lower than Firefox 40 and quite far behind Chrome 44 and Opera 29.

Edge - HTML5Test comparison

While it’s good seeing all these improvements from Redmond, what matters more are the improvements from other areas, such as the support to the extension model, etc.
