That annoying thing of not being able to delete specific port-forwards is still there but a lot are screaming about it on the forums so by actual SP2 release we might have an improved port forwarding page. It will be interesting flashing two routers with the new version in a place I installed two WHR-HP-G54's in WDS (wireless bridging) mode and it's not always brilliant, if it sorts it out they'll be over the moon. WMMS seems to be more complex looking although I never do much with it and there's a new feature 'EoIP' - 'Ethernet over IP Tunnelling', which sounds VPNish like when I read the description, but without the IP protocol necessarily in use completely 'Bridge LAN's over the internet'. There are little changes here and there for example the way the command section is layed out. I had literally no problems with V24 SP1 anyway but I'm curious to see if there's anything new in this one. I've just flashed my Bufallo WHR-HP-G54 and so far everything is looking good. Checking out the number of nightly builds from BrainSlayer it looks as if they're working pretty quick on a final version so wouldn't be much time to wait.
