Microsoft has been working on a new browser that they currently call Project Spartan. While the name has not been finalized, this new browser represents a break from Internet Explorer and has many new features too.
At Mobile World Congress today, Microsoft confirmed that Spartan will be included in the next preview release of Windows 10. Many were hoping that Microsoft would have released a build in February but alas, it is now March which means that the last release came in late January.
Spartan is a modernized browser, meaning it does away with a plethora of legacy code that is included in Internet Explorer; this means that it should run faster and use less resources. Along with new features like support for inking and reading mode, Spartan is Microsoft's future web browser.
Many users are anxiously waiting to get their hands on the new browser to run it through benchmark testing but it should be noted that this platform is in development which means there is likely a significant amount of optimization to be done before the final release.
While Microsoft is not saying when the build of Windows 10 will arrive, we would expect the next release to occur this month.
