We have not really explored going to netty 4.0. I know at some point we will probably have to switch over to use it, but for the time being most of the dependencies that we have seen still use netty 3.X, but if you have code to use netty 4.x and want to contribute I would be happy to review it and see what we can do to support that. Even if it involves doing some shading to support it. - Bobby

From what I understand, Storm (at least till the 0.10.0 dev branch I checked out) still depends on Netty 3.x. and Netty 4.x is not compatible with 3.x code Link <http://netty.io/wiki/new-and-noteworthy-in-4.0.html>. I could not find any related issues in the Apache Storm Jira, and is curious to know if anyone has explored implications and impact of such a change. Regards, Julian
