Motivation: Estimation algorithm currently used for WriteTasks is complicated and wrong. Additionally, some code relies on outbound buffer size incremented only on actual writes to the outbound buffer. Modifications: - Throw away the old estimator and replace with a simple algorithm that uses the client-provided estimator along with a statically configured WriteTask overhead (io.netty.transport.writeTaskSizeOverhead system property with the default value of 48 bytes) - Add a io.netty.transport.estimateSizeOnSubmit boolean system property allowing the clients to disable the message estimation outside the event loop Result: Task estimation is user controllable and produces better results by default

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
The 'master' branch is where the development of the latest major version lives on. The development of all other 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.
