netcfg v2 is a complete rewrite of the netcfg that was previously included within 'initscripts'. netcfg v2 has been moved into a different package 'netcfg'. netcfg v2 is feature compatible, but not configuration compatible. Configurations need to be rewritten for netcfg v2, and examples are included in /etc/network.d/examples. For more information on transitioning to netcfg v2, please check the wiki: http://wiki.archlinux.org/index.php/Network_Profiles
The latest release of perl 5.10.0 has been moved to core. This package is built following the Perl Policy document found on the wiki. Pay attention to the upgrade notes because some things have changed and may require some action.
