Re: 2.6.13 and AS 4.2.3, I personally haven't tried any 2.6 series release with AS 4.x. So I'll defer to the rest of the community for detailed input. The 2.6 series is API compatible with the 2.4 series used in AS 4.2.x, and the fundamental semantics of Channel behavior are the same, so it should work fine. There are some pretty major configuration differences, but you've already seen those with your 2.6.10.merge efforts. I wouldn't expect problems moving from 2.6.10.merge to 2.6.13.
