I've downloaded 11 books that were published on or after 2023-Jan-03. They all give the PCMAC_126 error message when attempting to download using K4PC and/or K4Mac. They all downloaded as azw3 files when using Download and transfer via USB (registered device is a PW4) and calibre was able to import them (I do have an eInk Kindle with it's serial number registered in the DeDRM plugin).
In my personal opinion, this is not a change in DRM but rather an issue with Amazon disallowing downloads by older K4PC and K4Mac applications based on publication date.
