No mention of R5, R6 or IBIS

・Focusing performance has been improved when using the Servo AF continuous shooting mode.

Computer updates can be risky at times but at least I can reformat and reinstall from scratch. Cameras and lenses, not so much if the update process screws up. Kinda makes me nervous there are so many updates for the R series when its still so relatively new.

Not an EOS R5 owner in the near future but even so I have updated my 4 RF lenses. Also, I updated my EOS R. So here is your guinea pig :D
Everything went smoothly!
Have you noticed any improvement in the IS with you EOS R? I thought these updates were solely for EOS R5.?

I haven't applied it yet, but the lens firmware is specific to the R5/R6. But the R/RP firmware gets you a few new options plus covers you for the new glass that's coming.
