Major version release? Now, I'm totally lost. The optiboot page authored by Bill[ie, westfw] gives no indication of a version 5. So ?https://code.google.com/p/optiboot/
Bobuino has SCL/SDA in the correct place too.
how could you map these into the A4,A5 positions?
I'm a big fan of the 1284 as I'm using it on a my custom boards for electronic props for compat games.I like the idea of an Uno or Mega compatible footprint, although most people using 1284 are probably at a stage where they'd be designing a board, or using something like Crossroads Bobuino board. Still, it's a good idea as another option for people into this nice little MCU with the extra resources that will satisfy many larger projects.I notice that SPI and UART are on incompatible pins than Uno. The Bobuino pinmapping makes these compatible, RXT/TXD on D0/D1 and SPI on D10-D13. You have SPI on D4-D7 and RX0/RX1 on D8/D9.Surely a standard shield won't work with your pins as is? An SPI shield may do, if it uses the SPI header, rather than pins 10-13, although I believe the Ethernet shield uses Pin 10 for its SS, whereas you have SPI on D4-D7
