Microsoft released Windows 10 21H1 Preview Build 21292 from the RS_PRERELEASE branch to Windows Insiders in the Dev Channel earlier this week. The company has now released a cumulative update designed to test its servicing pipeline - something that the Windows development team has started doing quite often.

Windows 10 Cumulative Update Build 21292.1010 (KB4601937) does not introduce any new features, but does move a previously fixed issue back to the list of known issues after Insiders reported it.
