Canon’s “flagship” 1DX Mark III benefits from a firmware update (1.2) released last night, which includes the addition of 23.98P shooting for cineasts who like to use 4k UHD and FullHD. It also increases networking speed, and finally – eight months after launch – fixes the crash issue that plagued users of the electronic viewfinder level. It appears the superior R5 eye tracking is making its way back to the DSLR with this update, in particular the ability to narrow the focus point to the eye from a greater distance. Finally, some of the R5’s nifty remote access features have been ported back, allowing for remote browsing of images and the option of transferring only those images that have been marked as protected.

As the Canon US site fails to put the release notes on the page, and it is not in the actual firmware compressed package, here are the English release notes as downloaded from the UK:
