Today we’re excited to announce the availability of a new build for Windows Insiders with the first preview of “Project Spartan,” the new browser for Windows 10. You can learn more in Joe Belfiore’s blog post, “Introducing Project Spartan: The New Browser Built for Windows 10.”
This build does not yet include all the changes we announced last week, so the new rendering engine can still be enabled in Internet Explorer under “about:flags” by selecting “Enable experimental web platform features.” This will be removed in a future update.
Project Spartan includes some new rendering engine updates in this flight, which we’ll detail in future posts. Notably, we are excited to announce preview support for the
<img srcset> attribute for responsive images.
You can try out Project Spartan yourself in the new build via the Windows Insider Program and share your feedback on Twitter at @IEDevChat and in the comments below. Feedback on the Web platform powering Project Spartan should continue to go to the Web Platform Suggestion Box, and we welcome your feedback on Project Spartan itself at the brand new Project Spartan Feature Suggestion Box. Let us know what you think!
– Kyle Pflug, Program Manager, Project Spartan
Update 3/30/2015 at 6:00 PM: The original post erroneously stated that Internet Explorer can no longer access the new rendering engine in this build. This has been corrected to indicate that Internet Explorer can still enable experimental web platform features in about:flags, which will be removed in a future update.
