Here's where I first heard about it. You have to read through the Support Board to know what they have in mind. When I first saw this they said they "intend to phase out CQG support 100% by year end". Since, they have back-tracked a bit... saying they "still might offer CQG in Package 11 and 12, but "probably at a higher price". ??

I didn't receive any notification from SC at all... that "Package 3 will have only delayed data, not real time,
beginning with service renewals after April 15... and suggest if you want RT data consider packages 5, 10, 11, 12".
Refer to the following for how to setup Denali for the CME Group data:
Denali Exchange Data Feed: *Setup Instructions: CME Exchanges* (link)
My renewal date is April 16. I didn't want to challenge their LIS of April 15, so I upgraded from Package 3 to Package 10 yesterday. In spite of the first instructions I encountered, I didn't have to change any settings or symbols... just did the Denali "signup/activation". It was easier than I was lead to believe.
(I was surprised to see that after upgrading my Selected Service is still "CQG Web API".... I thought it would change to "SC.. All Services", and I would have to change the symbols... but no. Then again, I wouldn't be surprised to eventually learn that they are not telling us the "whole story".)
