Microsoft compiled the new Win10 development branch

Computer store news: Microsoft's current Windows 10 Build development branch sent to Windows Insider users is "fbl_awesome1501". FBL stands for "Feature Branch Level",“awesome1501” stands for "awesome in January 2015”. Of course, since January 2015 has passed, this may mean that it is time to start a new branch name, fbl_impressive.

Microsoft compiled this new branch on February 7, but it only appeared in public records until today. It is widely believed that this will replace the fbl_awesome branch, which is not unreasonable, as Gabe Aul recently hinted at a new Windows Insider branch, saying it would be very "impressive".

The first known build compiled in the fbl_impressive branch is build 10013, which is more than the 10009 update we saw in the screenshot. Hopefully this means that Microsoft is ready to release the public build of the Spartan browser for testing, but this first requires fbl_impressive to be released to the public. Currently, there are still some 993x builds compiled in the fbl_awesome1501 branch that have not been used yet. Maybe Microsoft will release these 993x builds before jumping to the 100xx series.
