Release Candidate 7 of DD-WRT v24 has been released. The forum reviews at their site report it as being stable. This does have the newer chipset drivers, enabling the option for "Bluetooth Co-Existance" capability. Thinking of all the Bluetooth things in your house (phone, game system controllers, etc) it's not a bad feature to enable.
It is suggested to wipe your settings after the upgrade to make sure you don't end up with old junk settings that screw up performance.
