Microsoft today confirmed that their new web browser Project Spartan won’t be part of the new preview build that will released to Windows 10 Insiders next week. But the Internet Explorer in Windows 10 will include lots of updates to the web rendering engine that will power both Project Spartan browser and IE.
The following are the new platform features that will be released,
- HTTP Strict Transport Security (HSTS)—an HTTP header to inform the browser to always request a given domain over SSL, reducing MITM attack surface area.
- HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (DASH) –expands our plugin-free adaptive video streaming to support the popular HLS and DASH protocols.
- Video Tracks — adds the ability to get information about multiple video tracks, and switch between them using the VideoTrack.selected attributes.
- DOM L3 XPath – initial support for accessing the DOM tree using the XPath syntax. Expanded support will come in a future release.
Additionally, you’ll find updated F12 developer tools that include the updated UI we shipped to IE11 users last month as well as several new features and improvements.
- New and Improved Network Tool—capture and debug network traffic with new UX and capabilities, such as auto-start, a content type filter, and error highlighting.
- Async Callstacks for Events and Timers—quickly view the “async callstack” to connect the dots between event dispatch and the original addEventListener call or between setting a timer and the timer being fired.
- Sourcemaps for Styles and in the Memory Profiler—jump to your original sources, such as TypeScript or SASS, directly from the Styles pane or Memory Profiler tools.
- Find Reference and Go To Definition—jump directly to a function call’s definition or find the references to a given variable.
If you want to get the new engine, you can opt-in now, remember to navigate to about:flags and set “Enable Experimental Web Platform Features” to Enabled.
