It still doesn't look like the all of the update servers have been updated (or are ultra busy) as my win7 netbook, which hasn't been used for beta builds reported 2015.10.0.2208 was up to date.
A further manual check appears to be downloading, however it is very slow and may even be stalled, has sat at the same progress point for over 5 minutes.
On my XP Pro system which has been used in the beta and RC builds has just thrown up a popup program update available. Update has completed on that (but the other system is still stalled) and I'm about to reboot.
