Request your installation/upgrade to 5.3.0 now everyone! :) :) :)

I have requested day after Squiz summit and still can’t get date for even March/April. I have 2-3 major development coming in the next 6 months and it would be super useful to use some the new features but unfortunately the Squiz upgrade model is the bottleneck.
