A list of improvements in firmware version 1.2.1 is listed below.

1. Uncompressed HDMI output is now enabled.
2. Enables the center AF point to autofocus when the camera is used with Canon EF lens/extender combinations whose combined maximum aperture is f/8.
3. Improves the speed of the camera’s acquisition of focus when using a Canon Speedlite’s AF-assist beam.
4. Fixes a phenomenon in which the LCD monitor may freeze and display Err 70 or Err 80 when a still photo is taken during Live View or in movie shooting mode.
5. Fixes a phenomenon that may occur when the continuous shooting priority setting is enabled for multiple exposures, such that, after the sixth image is taken, there is a slight pause before the remainder of the sequence is completed.
6. Fixes a phenomenon in which the viewfinder display shows incorrect information during AEB shooting.
7. Communication with the WFT-E7 Wireless File Transmitter has been improved.
8. When images have been successfully transferred with the WFT-E7 Wireless File Transmitter through the FTP protocol, an “O” will be displayed. When images have not been successfully transferred with the WFT-E7 Wireless File Transmitter through the FTP protocol, an “X” will be displayed.
9. Fixes a phenomenon in which the camera may not function properly when an Eye-Fi card is used.
10. Fixes a phenomenon in which the focal length value listed in the Exif information is not displayed correctly for images shot with the EF 24-70mm F4L IS USM lens.
11. Fixes a phenomenon in which the lens firmware cannot be updated properly.
12. Corrects errors in the Arabic language menu.
13. Fixes a phenomenon in which the camera changes the AF microadjustment value to -8.
14. Fixes a phenomenon in which the on-screen guidance cannot be fully displayed when setting the maximum limit value for the “Setting the ISO Speed Range for Auto ISO” option.

You can still use them, but you get a warning and they are shown as 100% charged.

There are 15 bullet points in total according to Canon Europe, the missing one is number 14, it should be "The lens compensation data for the EF24-70mm f/4L IS USM lens has been added."

Have already downloaded it but haven't installed yet ... Excited and can't wait to get back home to install

The 6D firmware already has this "feature" ...  Somewhat annoying, but I still use my 3rd party batteries.  I just have to make sure I always carry a charged spare, since I can't tell how much juice the one in my camera has.

any comment on image quality?

Is this for ANY third-party batteries?

Have there been firmware updates for Canon lenses that are loaded through the camera?

yes, for 40mm pancake

[psolberg]

waiting on EOSHD to do a full test, but so far his early conclusions is that the uncompressed HDMI only yields minor improvements. If this is the case, the soft output of the 5DmkIII compared to other cameras, as documented on many of his tests, may in fact be impossible to fix with a firmware update, at least one from canon.

So, why are there two versions for windows in the canon usa site http://usa.canon.com/cusa/professional/products/professional_cameras/digital_slr_cameras/eos_5d_mark_iii#DriversAndSoftware ?

Just upgraded my camera to the new firmware.  I can confirm with the 600ex-rt, the autofocus with AF Assist beam is indeed noticeably faster.

Also noticed a small interface change.  Before the update when you turn the camera on you would get an almost fullscreen icon of the sensor cleaning process.  After the update, you get the Q screen with a small animated icon in the bottom right corner showing the sensor cleaning process is active.
