Download firmware v2.0.9

This is another case of the main EOS Digital site not having the latest firmware update information on it. These firmwares are only shown on the Canon Europe and Canon USA websites, which seems to be a change from the past when official firmware was only available for download from Canon’s main site in Japan.
