it's due to pulldown-cmark{,-escape} being out of sync, not mdbook itself.
The error is like this: error: failed to select a version for the requirement `pulldown-cmark = "^0.9"` candidate versions found which didn't match: 0.10.3 So you are relying on an *older* version which is no longer available. I don't see how this could be not a bug in mdbook. Thanks.
