Why aren't I receiving new builds (Stuck on build 10080 for months)?

[WPCentral Question]

I don't seem to be receiving new builds (Stuck on build 10080 for months)

I never actually downloaded the Technical Preview (I'm still running 8.1) because of all the bugs reported
but I was thinking about doing the one that is coming next week (I have a 930)

Do I have to first update to this build (10080 / 10.0.12562.84)?
