Re: preprocessor normalize_tcp: ips ecn stream dropping SYN retransmission

[Joel Esler <jesler () sourcefire com>]

We don't release the roadmap of Snort ahead of time externally yet.  While there isn't much that will affect 
installation and usage in 2.9.4, I will have to start talking about 2.9.5 ahead of time, as it's going to change a lot 
of things.
