If I try to build my otherwise unchanged book with mdbook v0.5.1 and tera 0.6.0, I get this error:

mdbookversion 0.5 introduced breaking changes to preprocessors. All of the preprocessors, includingmdbook-tera, need to be updated. Here's the version 0.5 migration guide.In the mean time, I recommend using
mdbookversion 0.4.52.Hoffenbar commentedon Jan 29, 2026
