The key difference between the two builds is that Build 22631.2115 rolls out new features while Build 22621.2115 keeps them off by default.
“Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 22621.2115 and Build 22631.2115 (KB5028251) to the Beta Channel.”
Major Updates
Insiders who were previously on Build 22624 will automatically be moved to Build 22631. This is done through an enablement package, which artificially increments the build number for the update with new features. This approach is exclusive to the Beta Channel.
Opting for New Features
Insiders in the group with new features turned off (Build 22621.xxxx) can choose to install the update that will have features rolling out (Build 22631.xxxx).
August 2023 Bug Bash
Starting August 2nd, the next bug bash will take place. This event will cover the latest features available in preview builds across the Canary, Dev, and Beta Channels.

Fixes for Both Builds
Both builds bring several fixes affecting the Handwriting Software Input Panel (SIP), the Handwriting Engine, Handwriting Embedded Inking Control, and text edit controls in XAML. They also address issues affecting the Windows Kernel Vulnerable Driver Blocklist, certain CPUs, wireless wide area network (WWAN) devices, user mode printer drivers, and hybrid joined devices.
