Post here what you'd like to see for b5. Wishlists, known bugs in b4, and todos (in case you're a developer).
These issues has been addressed in the CVS version:
Support for static IP and /etc/resolv.conf (wan_dns). Inability to bring up the 802.11g interface on 1.x box (wl0_macaddr issue).
Note: If you need the aforementioned fixes, delete sources/dl/root.tar.gz and recompile the firmware - It should download the updated root from the CVS during the recompile.
These issues needs to be addressed before b5 is released:
Support for pppoe (pppoecd.mk and few files in the romfs)
