This is rather long series. Please, start from the fixes series first that is independent on the features. I see here ~3 sequential series. Can we rather do them this way? Personally I stopped reviewing on patch 12 (without even opening DT stuff) because it's exhaustive. Documentation usually suggests the series to be limited by ~15 patches IIRC. -- With Best Regards, Andy Shevchenko
