Over the past few months there has been some development on a new ET client. As of now its a work in progress client and will be subject to change and updates over the next few months.
Right now the client fully supports lua and has a lot of settings you can tweak and change.
Our biggest accomplishment so far with this client is that we are able to fully support ETpro 3.2.6 without any problems.
ETpro 3.2.6(non punkbuster)
Jaymod 2.2.0 ( also supports F|A Servers )
I will post the lua script that we have made so you can get a general idea of what can be capable with this client. As of now its private and will be released soon with full feature and api wiki.
Heres a small video showing it working.
If anyone is interested in testing it out privately and/or help make scripts for it feel free to get in contact with me.
