Microsoft has released a pair of new Beta Channel builds for Windows 11 today, 22621.741 and 22623.741. The builds contain mainly fixes, but if you were on build 22622 you will automatically get moved to build 22623 via an enablement package:
The enablement package artificially increments the build number for the update with new features getting rolled out and turned on to make it easier to differentiate from devices with the update with features off by default. This approach is being used for the Beta Channel only and is not indicative of any changes or plans for final feature rollouts.
In addition, "Insiders who landed in the group with new features turned off by default (Build 22621.xxxx) can check for updates and choose to install the update that will have features rolling out (Build 22623.xxx)." Confused yet? Anyway, check out the Windows Insider blog post for all the details.
