Directly after our last lighttpd announcement where we wrote about the (in our view) deprecated option server.set-v6only we have been contacted by a lighttpd developer who corrected us. To cite him:server.set-v6only still exists as an option, though I have removed someof the documentation. server.v4mapped should be used, instead.
Our perl versions were outdated for quite some time. Finally the old versions have been replaced with 5.34 and 5.36.
