Redis Client lettuce 3.3.Beta1 and 4.0.Beta1 released

Details: 06 August 2015

I released today two betas of lettuce: 3.3.Beta1 and 4.0.Beta1. What is the difference between those versions? Both use netty and a very similar core to serve as Redis driver. The 4.0 branch introduces a Reactive API, stateful connections, improved API and command execution on multiple cluster nodes. 4.0 also introduces a set of breaking changes. The 3.x branch is supported for at least a year, new Redis commands will be supported in both branches. 4.0 is the next generation of lettuce.

You can find the details of both releases on Github, here's the short version:
