In a post dated 5-5-22 (yesterday), Leica Store San Francisco's blog is announcing new a firmware update 4.22.11.52 for the M10 Monochrom and other M10 cameras.
It is odd that this has not been announced and posted here, but I am not finding it in the M10 Monochrom forum.

Just found it in the M10 section: https://www.l-camera-forum.com/topic/332171-leica-m10-p-r-m-d-firmware-update-brings-compatibility-with-the-new-evf2/
Apologies for the oversight.
