Thanks for the advice. Would I be correct in thinking that, if I do the 1.3 install, it will include all the improvements and bug fixes covered by the previous firmware upgrades, i.e remote flash and more comprehensive configuration of e-dials, etc?

I am either confused or dim, but this whole issue of firmware upgrading is baffling me. I received a shiny new K10D from Santa and after much messing about and proding and poking, I noticed that it has firmware version 1.00. I also noticed that the latest firmware available is 1.3 and according to the instructions for upgrading to the latest version, I need to, I quote "Make sure your camera currently has firmware version 1.00 through 1.20.".
The trouble is when I went searching for version 1.10, on the Pentax website, the earliest version I was able to download was version 1.11. Even though I found the link to version 1.10 it took me to the download for 1.11 and if I clicked the link for version 1.20 it took me to the download page for 1.30.
I suppose my question is, is it necessary to upgrade up to 1.20 before I can install 1.30?
