Now the firmware update is also available for the Canon R6, which should give users longer recording times and shorter waiting times when filming in demanding video modes. The release notes for version 1.1.1 read exactly the same as for 
update for the Canon R5, so you can assume that the heat limits are actually improved.
Furthermore, the stabilization in video mode is also improved for the R6 and the interaction of the stabilization with the RF 100-500mm F4.5-7.1 L IS USM is optimized.
Meanwhile, by the way, the circumvention of the heat limit for the R5 and R6 was optimized by users in the Magic Lantern Forum with a simple trick optimized. So it is not even necessary to rip the battery out of its compartment while recording and risk damaging the file system of the memory card, but it is sufficient to change the date of the camera after overheating and then immediately remove the battery to mess up the internal timer. (If you film for a very long time in this way (with repeated interruptions, of course), you do this of course at your own responsibility).
