It has been discussed and post in lots of webboard for weeks. However, it hasn’t been released to the public yet. The Canon 40D firmware 1.1.0 (then later 1.1.1) still not appears on official Canon support download but those who went to service center all got the camera back with 1.1.1. Until K.Ber8 got the 1.1.1 firmware from Sathorn Service Center and distribute in this post. There is no document what has been updated but new version always good, right?
Those who want to try it can download directly from here. At least please leave some comment to let me know that there is still people interesting.
WARNING: Please upgrade firmware at your own risk. At least mine works.
UPDATE (Jan 20): Now it is official. Please see the release note and download the firmware from here
UPDATE (Jan 28): Remove the local file by Canon’s request. Please use the official link here instead.
