Firmware Version 2.1.1 incorporates the following fix:
1. Corrects a PTP communications vulnerability.
2. Corrects a vulnerability related to firmware update.
Firmware Version 2.1.1 is for cameras with firmware Version 2.1.0. If the camera's firmware is already Version 2.1.1, it is not necessary to update the firmware.
When updating the firmware of the camera, please review the instructions thoroughly before you download the firmware.
Notes:
1) Once the EOS-1D X camera is updated to Version 2.0.9 (or later), it cannot be restored to a previous firmware version (Version 1.0.2 through 2.0.8).
2) It is recommended that the latest application software*1 be used, once the EOS-1D X is updated to the firmware Version 2.0.3 (or later) from older firmware (Versions 1.0.2 through 1.2.4). Certain previous versions of these applications do not support functions which are added by the new firmware.
You can download the latest application software from our Web site.
*1: EOS Utility version 2.13.30 or later
*1: Digital Photo Professional version 3.13.50 or later
3) Accompanying the enhancements to the functions, the instruction manual has also been revised. Users are asked to download both the latest firmware and the instruction manual. You can download the latest instruction manual from our Web site.
4) As a result of this fix, cameras with Firmware Version 2.0.7 (or later) will not be able to read the "camera settings file" created with cameras running Firmware Version 2.0.3 (or earlier). If you require the "camera settings file", please create it after updating to firmware version 2.0.7 (or later).

(The following is the history of past firmware updates)
Changes in Version 2.1.0:
1. Fixes a phenomenon in which standard exposure may not be obtained, or an irregular exposure may result, when Silent LV (Live View) shooting with the following TS-E lenses: TS-E 50mm f/2.8L MACRO, TS-E 90mm f/2.8L MACRO, or TS-E 135mm f/4L MACRO.
2. Changes the maximum number of “Release cycles” displayed from 1,000,000 cycles to 9,999,000 cycles. This value can be checked under the “Camera system information” menu.
3. Fixes a phenomenon in which a synchronization failure may occur during multiple flash shooting.
4. Fixes a phenomenon in which Error 80 occurs depending on the shutter release timing.
Changes in Version 2.0.9:
1. Corrects a phenomenon in which when using the camera with the EF 70-300mm f/4-5.6 IS II USM lens, even if lens aberration correction is set to "Enable", correction will not be applied.
Changes in Version 2.0.8:
1. Fixes a phenomenon which occurs when the "Shutter button half-press" menu item, configured in "C.Fn5: Operation" > "Custom Controls Menu", is set to metering start only; depending on when the shutter button is half-pressed, it may initiate AutoFocus.
Changes in Version 2.0.7:
1. Improves the AF controllability when shooting in Live View mode with a wide-angle lens (fixed focal length or zoom).
2. Fixes a phenomenon in which, when shooting long exposures (several minutes), vertical lines appear on the right edge of captured images (still photos).
3. Fixes a phenomenon in which the Auto Exposure Bracketing (AEB) may not perform as intended when in continuous shooting mode and where the shutter speed is longer than 1 second.
4. Improves the reliability of the control mechanism for the Picture Style Auto setting.
5. Fixes a phenomenon in which the electronic level indicator does not work correctly.
6. Fixes a phenomenon in which, when using the "Save and read camera settings" function, the color space data that is selected in "Custom shooting mode (C1-C3)" is not saved. *
* As a result of this fix, cameras with Firmware Version 2.0.7 (or later) will not be able to read the "camera settings file" created with cameras running Firmware Version 2.0.3 (or earlier). If you require the "camera settings file", please create it after updating to firmware version 2.0.7 (or later).
7. Corrects some incorrect indications on the "English" and "Russian" menu screens.
Changes in Version 2.0.3:
1. Auto focusing performance under low-light conditions has been enhanced when performing focusing before shooting in AI Servo AF mode. The enhancement comes from the improvement in tracking capability for the first image in the low-light conditions.
2. The number of release parameters settings for the "AI Servo AF 2nd image priority" AF function has been increased to enable improved AF tracking in low light or maintain consistent high frames rates during continuous shooting.
3. The number of parameters for acceleration/deceleration tracking in the AF Configuration Tool will has been increased.
4. Exposure compensation can be performed when using manual exposure and ISO Auto.
5. The minimum shutter speed limit for ISO Auto has been increased with shutter speeds up to 1/8000.
6. A new function to keep the exposure constant by altering the ISO or shutter speed in manual exposure, when the aperture value changes when zooming or changing lenses has been added.
7. A new option has been added to orientation linked AF point to enable only the AF point to switch as you change orientation rather than both AF point/ AF area settings
8. A new option to continue to use the previously manually selected AF point as the initial starting AF point when switching to 61-point automatic selection has been added.
9. New customization of the Exposure metering and AF controls has been added for more flexibility.
10. The number of possibilities for controls to switch between one-shot AF and AI Servo AF using custom controls has been increased.
11. A function has been added to allow the playback and review of protected images only.
12. A phenomenon has been fixed in which the white balance may be disturbed by the timing of the shutter release when the drive mode is single shooting and a flash (E-TTL)is used.
Changes in Version 1.2.4:
1. Improves the speed of the camera's acquisition of focus when using a Canon Speedlite's AF-assist beam.
2. Reduces the time it takes to display the metering result on the LCD or Viewfinder when the meter has been activated.
3. Fixes a phenomenon in which a "Caution 02" message is unnecessarily recorded in the camera status log.
4. Fixes a phenomenon in which continuous shooting pauses when using a Canon Speedlite.
5. Fixes a phenomenon, when the Canon GP-E1 is attached, in which the GPS device settings are reset to default settings when the camera has been powered off.
Note:
* This phenomenon occurs only with firmware Version 1.2.1.
* After changing the GPS device settings, please be sure to power off the camera before removing the battery. This will ensure that the camera's GPS device settings will be saved.
Changes in Version 1.2.1:
1. The function to disable the Image size selection button has been added.
2. Fixes a phenomenon in which Err 70 and Err 80 may occur during certain shooting conditions.
Changes in Version 1.1.1:
1. Enables the center AF point to autofocus when the camera is used with lens/extender combinations whose combined maximum aperture is f/8 (f/5.6 without the firmware update).
* Please see the "Lenses and Usable AF points" section of the revised instruction manual for more detail on the lens & camera combinations.
2. Displays the viewfinder information (such as the AF frames, grid, etc.) in red during autofocusing in AI Servo AF.
* When shooting in dark environments during AI Servo AF, the AF points can be easily confirmed.
* During AI Servo AF, the viewfinder will be lit intermittently, not continuously.
3. Corrects a phenomenon in which the metering value of the AE sensor becomes incorrect and the captured images become pitch-black depending on the timing of lens attachment and/or detachment.
4. Fixes a phenomenon in which Err 70 may occur during AEB shooting.
5. Corrects errors in the Arabic menu.
6. Fixes a phenomenon in which the firmware of the lenses cannot be updated normally.
