A couple of weeks ago Canon released firmware v1.3.2 for the Canon EOS 5D Mark IV. It was a minor firmware update, but earlier this week Canon pulled the firmware. The exact reason Canon pulled it was unknown at the time.

A Canon Rumors reader has sent me communication from Canon USA that explains why the firmware was pulled.

From Canon USA

Firmware version 1.3.2 caused a phenomenon when using the self-timer shooting (10 seconds) with the electronic sound set to “ON” where the timer will repeat for 10 to 3 seconds and does not shoot.

This firmware version has been removed from our website and a current fix is being implemented. This fix is expected to be released in the first half of June, there is not an exact release date available at this time.

It's great that canon is still trying to improve their current hardware with software/firmware upgrades. Gives confidence as a buyer.
