Can we know exact expiration date of this build since if there is no expiration date told for this build, insiders could easly end up with unbootable device due to expired build of non-production build of Windows.
And is this security mehanism still active or it's turned off for these builds so that insiders who joined Dev/Canary channels to test 24H2 version will be able to migrate to more stable channels in the future or even if they want, to decide to wait for final production release and upgrade to that version while perserving all settings, user data and apps since upgrading to the current build number and higher build numbers are possible with this option - it's only impossible from higher to lower builds without clean installation of Windows
