Manganese (Insider Fast Ring)
This version is notable for having the first Insider Preview builds released before Windows 10 November 2019 Update, which it has replaced. It is the last Windows 10 feature update to use the former YYMM scheme for the version number which had been used since Windows 10 November Update as Microsoft started to use the Azure YYHx scheme for future updates starting with Windows 10 October 2020 Update. It is the last Windows 10 feature update to add any notable major new features as later Windows 10 feature updates were minor updates that primarily focused on feature additions, bugfixes and security updates targeting enterprises, as Microsoft would shift future major feature development to Windows 11.
After its release, Microsoft released a number of new builds to the Dev Channel (formerly the Fast ring) that were not tied to any particular Windows 10 release (Manganese, Iron, and Cobalt), while the Beta Channel (formerly the Slow ring) received builds of the Vibranium-based October 2020 and May 2021 updates and the Release Preview Channel received updates to this version.
This version of Windows is codenamed after the fictional metal element from the Marvel Comics universe. The name was chosen in place of Chromium to prevent confusion with the web browser project of the same name.
