Canon EOS 50D Firmware

[Zeewayz]

Hello, I recently got myself a canon eos 50D, but the firmware version in it is the 1.0.3, in order to update it to the current one ( 1.0.9 ) do i have to update it to 1.0.4, 1.0.5, 1.0.6 .. etc. If yes, would you please give me the links to download the firmwares because i can't find them, I only found the recent one 1.0.9. Thank you very much
