Note: Microsoft is retiring the Redstone code name for OS development with the 19H1 designation replacing it for future feature update development. The code name breaks down into two elements with the 19 representing the year of the updates release and the H1 indicating it is going to be released in the first half of 2019. The next update will be code named 19H2 to indicate the second half of 2019 for its release. Subsequent update development cycles are expected to follow similar naming formats.
