Canon's BeBit website has posted firmware v1.1.0 for the EOS 5D and the EOS-1D Mark II N.
The update for the EOS 5D includes enhanced support for direct printing with two upcoming Canon Pixma printers and fixes two fairly esoteric bugs, one related to EOS Capture software and another involving uncommanded flash mode setting changes when using a Speedlite Transmitter ST-E2 and a Speedlite 580EX.
The update for the EOS-1D Mark II N includes only the direct printing enhancements.
