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...

By "electronic sound" if they mean the beep, mine is working fine in both the 10 second and 2 second delay.

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

Thank you, but I gonna wait a bit again when the fixed update is out - to be on the safe side. But I appreciate that Canon still releases firmware updates for the 5D4. I still like to use mine, and I don't care about those "DSLRs are dead" sort of postings. The future of DSLRs is over, no doubt, but as long as my old steam engines can deliver good images in my steam-punk-hands, I use them.

Incidents like this is why I delay updating my devices by 30-90 days. This gives the manufacturer the opportunity to fix any flaws that early adopters will encounter.

Last thing a working photographer or someone like me want to deal with is down time due to faulty software.
