We have recently released the Symbian^3 snapshot quality metrics for December. We have included a comparison between the functionally complete Symbian^2 baseline (PDK2.0.0) and the first Symbian^3 (PDK3.0.a). I was expecting these two versions to be significantly different, and here are the results per Technology domain:
The overall change reflected by the metrics is lots of activity in the UI domain – UIaccelerator, Graphics and Homescreen seem to have the larger churn.
Hope this makes it clear that Symbina^3 is a substantial upgrade with respect Symbian^2. I will keep you post it on further progress.
