Wonder why the auto updater isn't picking up 68.2?

Think there was some reason why it wouldn't automatically update, 32vs64
bit versions perhaps? The release notes say ...

"Thunderbird version 68.0 is only offered as direct download from
thunderbird.net and not as upgrade from Thunderbird version 60 or
earlier. A future version 68.1 will provide updates from earlier versions."
