Microsoft will divide Windows 11 Insider beta testers into two groups and give them two builds

Build 22621.ххх and 22622.ххх with different included or blocked new and improved options and features.

Build 22621.xxxx will be shipped with new features locked, while version 22622.xxxx, on the contrary, will come with extended options and included add-ons.

The company explained that this approach will help to test whether updates can be released with default features disabled, as well as better analyze reports on the impact on the system of the inclusion of new features.
