As is usually the case, Microsoft did not roll out any cumulative updates through December. That means January's updates for Windows 10 are busier than normal. On the Insider Program, Microsoft is rolling out preview updates only available on the various testing branches:
Windows 10 Preview build 19042.782 for Windows 10 20H2
Windows 10 Preview build 21296 for Windows 10 21H1
Before getting into the details of those builds, it's worth noting Microsoft is also rolling out preview updates for Windows 10 1909 and 1809. However, these are stable build release that any body can get.
Yes, build 19042.782 is also for a stable build (Windows 10 20H2), but it is currently only available to Insiders. Starting with that preview release, it is available now on the Beta and Release Preview rings on the Inside. That means they should come to all Windows 10 users running version 20H2 in the coming weeks.

Tip of the day:
Do you often experience PC freezes or crashs with Blue Screens of Death (BSOD)? Then you should use Windows Memory Diagnostic to test your computers RAM for any problems that might be caused from damaged memory modules. This is a tool built into Windows 10 which can be launched at startup to run various memory checks.
