The last few Windows Insider preview builds of Windows 10 have offered few new features; instead these have focused on fixing bugs.
The latest build, released today, takes a step towards completion: it’s changed the operating system’s version stamp. Until now the previews have called themselves version 1803, the release from earlier this year. Today’s build updates that version label to 1809, showing that Microsoft intends to wrap up its development in September with an October release likely to follow.
Version 1809 will be the last of the five Redstone-codenamed Windows releases. The next release, likely to come in April 2019, is codenamed simply “19H1,” with Microsoft opting for date-based codenames to go with its date-based releases.
