This should never be released until there is some sort of notification/change log, in the Forum, Avast Blog or other medium.
Confusion would also be greatly reduced if Avast would stop using the same bloody BETA version number for a regular release.
The release process isn't happening in one second. Usually the whole process takes more than one hour and it doesn't appear on all servers at the same time. So for some time someone might be getting old and someone new version...
So there are 2 approaches:
1. post the release notes when the release is in process....then someone will complain that the links still point to old version
2. post the release notes with some delay after the release......then someone will complain where the heck are the release notes ;-)
which one you prefer?
