Hi guys
I understand your wishes but sorry it is too much time for me. I works on my freetime on wz4 and as you everyone I don't have unlimited amount of time, and a developpment activity need it a lot. I also work on other dev projects that require time too. Working on werkkzeug code is not so easy at begining as there is no support and no documentation and dive into the wz3 code to fix bug and release new features will need a lot of investments. I will also be honest with you, I don't use wz3, so it is difficult for me to works on this project without having a good knowledge of how to use it and without getting any advantages.
I hope a programmer will be interested to work for wz3, I'm agree that it has its own advantages over wz4.
However, I'm aware to try to port some wz3 features to wz4 if it is possible.
