I'd say hold off a little while until we're more certain on the planned interface changes, to avoid you rebase your code back and forth; unless you're pretty confident that this will be the right approach. I apologize on not having looked at any of the QAT/IAA compression / zero detection series posted on the list; I do plan to read them very soon too after Fabiano. So I may not have a complete full picture here yet, please bare with me. If this series is trying to provide a base ground for all the efforts, it'll be great if we can thoroughly discuss here and settle an approach soon that will satisfy everyone. Thanks, -- Peter Xu
