A couple of days ago the OpenWrt developers released WhiteRussian RC6 which will be the last WhiteRussian release. If it is working as expected it will be renamed OpenWrt 0.9 and no more WhiteRussian.

Instesad the devs will focus on the next generation of OpenWrt codenames Kamikaze.

The ReadMe file for the RC6 release can be found here: 00-README

The xmail tutorial is (ad you can see) a bit delayed. It will be done soon. I will also change the Installing OpenWrt Tutorial, as there is a few changes  (old tutorial will still give you a working system, some stuff is just not needed anymore :-) ).
