netcfg v2.1 is mostly a bug fix release, however there are some important changes and new features.

- Remove driver specific hacks/quirks. They now need to be enabled manually using the QUIRKS=() array. - auto-wireless has been moved from net-profiles to a separate daemon net-auto. - A new option (IWCONFIG) to run iwconfig with set arguments before connecting - Various minor fixes

Details can be found on the wiki for all these options http://wiki.archlinux.org/index.php/Network_profiles
