Last year, there was a few rumors about Windows Redstone, which is expected to get released in two waves (June 2016 and October 2016). Now, Microsoft seems to have started the official development of Windows Redstone. BuildFeed, a site which detects and tracks all of the latest Windows 10 builds is now reporting that a new build form RS1 (Redstone 1) has been detected:
RS1 branches are alive – rs1_onecore_mqbase1 has been detected!

Obviously, Redstone won’t get released to Insiders or the public anytime soon as Microsoft is yet to release Threshold 2 (which is expected to get released in November). Nonetheless, it will be very interesting to see what new features Redstone brings next year.
