Hmm, I'm not immediately sure on that one. There could have been a procedural error during the release process, but I don't see one.
An edge cache that wasn't fully purged, or even client-side caching, could theoretically cause that, but neither condition should have occurred.
In any event, I'll keep a close eye on it as this next build (9.7.5.44) is released to fix that Keep Awake submenu.
Unrelated, but just FYI, that the Server Edition update notifications are usually delayed a couple days.
If you continue to see that cyclic update behavior, please let me know.
