Re: [lwip-devel] Desiderata for 2.2.0: better support for Debian packaging and VirtualSquare

[Simon Goldschmidt]

Hi Renzo,

You're just in time, I was planning to release 2.2.0 these days. The main 
"improvement" would be that contrib is included in the main tree. I'll have a 
look into your patches.

Thanks,
Simon
