[lwip-users] Integrating lwIp into project: which branch to check out ?

[Andrea Vallinotto]

Hi everyone.

I'm working on a project where I would like to integrate lwIP; the project 
should have production-quality code or the closest thing possible.
I've cloned the repo as instructed at the homepage, thus I'm on origin/master. 
But is this the correct way to do it or should I instead check out STABLE-2_1_x 
? The latter is two years old and I can see some important changes in master 
since then.

So from which branch/tag should I start ?

Thanks.
