Motivation: Netty could handle "connection" or "te" headers more gently when converting from http/1.1 to http/2 headers. Http/2 headers don't support single-hop headers, so when we convert from http/1.1 to http/2, we should drop all single-hop headers. This includes headers like "transfer-encoding" and "connection", but also the headers that "connection" points to, since "connection" can be used to designate other headers as single-hop headers. For the "te" header, we can more permissively convert it by just dropping non-conforming headers (ie non-"trailers" headers) which is what we do for all other headers when we convert. Modifications: Add a new blacklist to the http/1.1 to http/2 conversion, which is constructed from the values of the "connection" header, and stop throwing an exception when a "te" header is passed with a non-"trailers" value. Instead, drop all values except for "trailers". Add unit tests for "connection" and "te" headers when converting from http/1.1 to http/2. Result: This will improve the h2c upgrade request, and also conversions from http/1.1 to http/2. This will simplify implementing spec-compliant http/2 servers that want to share code between their http/1.1 and http/2 implementations. [Fixes #7355]

How to build
For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.
You require the following to build Netty:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.
Branches to look
Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
