This is blocked on a new version of mdbook-svgbob being released with support for Rust 2024 edition.

When trying to manually build the book with these changes (after manual installation of mdbook-svgbob from the git repo - as there is no release yet) I get this error from linkcheck (0.7.7)

$ mdbook build

When linkcheck is disabled this change looks good to me.

Looks like mdbook-linkcheck has the same issue as mdbook-svgbob of depending on an old version of mdbook. mdbook-linkcheck hasn't had a release in over 2 years and seems unmaintained, but mdbook-linkcheck2 is an active fork which fixes the issue so I've switched to that instead.

There is still the issue with the new crate version mdbook-svgbob 0.2.2 not yet pushed but otherwise this now looks good to me!
