There is another firmware upgrade for the Fuji s700 (S5700). The stated improvements include further compatibility with Windows Vista and the 4GB card and improvements in communication from PC to camera.
Since there are sometimes other changes, I did the upgrade without a hitch. As always, be careful to follow the instructions exactly.
By the way the file size of the DAT file doesn't exactly match what is stated. I suspect that part of the instructional page was not updated from the last upgrade.
Also, one of the "secret" improvements of the last firmware upgrade (1.01) is actually now mentioned on the page. "Fix the issue that the lamp of self-timer does not be turned off only after shooting with 2-second self timer function is used with NO beep sound (beep volume setting: OFF)."
