Update to Windows Phone 8.1 Update 1 from WP8.1 DP

If my Lumia 920 using the Windows Phone 8.1 Developer Preview, should I need to update to the Official Update of Lumia Cyan before I want to update to Windows Phone 8.1 Update 1?

Short answer: Nope

Lumia Black/Cyan/whatever is a separate entity from Windows Phone 8, 8.1, 8.1 U1 but they are typically distributed together.

no... it is just a firmware update, and you can install it whenever you want (it also download windows phone 8.1 (update 0/original) if your current OS is lower than the OS it download)

Ok I just got denim....not sure if was the official one or DP is there a way to tell?
I just saw the notification you have an update..clicked it and it went straight into phone update...i didn't open dp....any way to tell where the update came from? Official or DP?

Same for me this morning. After the update I looked to see if I was still running DP & I was. Still had the box ticked.
I would say it was official.
