- The phenomenon in which the movie recording time available is not correctly displayed when the Date/Time/Zone is not set has been corrected.
Canon also announced that firmware update will be coming in early September that addresses the RF 100-500mm f/4.5-7.1L IS USM.

- Supports 6-stop image stabilization. (CIPA-compliant)
- Improves IS capabilities when performing continuous shooting under specific conditions.
Gordon Laing explains what he found using the firmware in regards to temperature control.
The update that's most interesting is the change in temperature detection. The camera will now check the three sensors more often, to give a more accurate real-time reading. There is some hope that there will be reduced cooldown times and longer record times because of this. However, Canon has not changed the temperature in which the camera will give you an overheating warning.
The 29:59 limit on record time has not been changed. Longer recording periods didn't see a significant improvement in record times or recovery times. Though there was some improvement.
However, in 4K120P, the Canon EOS R5 allows for 7 minutes and 30 seconds of record time. The new firmware does not increase that time. However, when shooting short bursts. With the original firmware, Gordon was able to record 22 30 second clips with 30 seconds of recovery time between each clip before the camera overheated. With the new firmware, that number increased to 96.
What is interesting, is that Gordon tested taking short clips at 4K120
