The Internet may have fun trying to guess the next natural feature of California or animal alliteration name for the other major operating systems, but Windows build naming conventions can be downright hard to parse. The latest officially released build was originally known as 20H1—meaning the first half of 2020. As it got closer to release status, it received its official build number: 2004, meaning April 2020. However, it didn't actually hit release status for another month, on May 27.

Maybe that's all indicative of what awaits users when they finally upgrade to Windows 10 2004; this is not Microsoft pumping out major changes like its debut of Windows 2000 roughly two decades ago. Still, a new Windows release is a new Windows release. So we recently spun up a fresh VM with a clean install of Build 2004 to take a look at its new features.
