Microsoft never sleeps. Even before Microsoft made the Windows 10 May 2020 Update (version 2004) generally available to users, the company began working on upcoming feature updates to Windows 10. As it did with version 2004, Microsoft has been releasing a series of public preview builds to members of Microsoft’s Windows Insider Program.
After years of using “Redstone” in its code names for upcoming releases, Microsoft switched to a new format with version 1903, released in May 2019. The code names now use a YYH1/YYH2 format, with the YY standing for the last two numbers of the year and H1 or H2 referring to the first or second half of the year. So Windows 10 version 2004, which was released in May 2020, was code-named “20H1” (for first half of 2020). The next feature update, due in the fall of 2020, is code-named 20H2.
