Please take note that build 25324.1011 was miswritten as build 25314.1011 on the official Windows Insider Program Twitter account.
Microsoft has released an update for Windows 11 Build 25324, which was made available to Windows Insiders on the Canary Channel yesterday and includes SHA-3 support in addition to numerous other improvements. As it is intended to test the servicing pipeline, it is available as Cumulative Update Build 25324.1011 (KB5025849) and contains nothing new.
As a result, this version includes all the bug fixes and enhancements that were promised with the earlier Build 25324 release to the Dev Channel. Interestingly, servicing test builds like these in the past has been known to break some features even though there are no new changes in this build. For instance, it caused problems for x64 emulation on ARM PCs in the previous version of Windows, specifically on Windows 10 Build 21292.1010.
