From the page:

https://mongodb.github.io/mongo-java-driver/4.1/driver/

I clicked the 4.0.5 API link to API docs which led me to a 404 at:

https://mongodb.github.io/mongo-java-driver/4.0/javadoc/

From inspecting the Hugo variables contained in mongo-java-driver/docs/landing/data/releases.toml on the 4.1.x branch, I would have expected it to render in the correct location as:

https://mongodb.github.io/mongo-java-driver/4.0/apidoc/

For some reason, the published version does not seem to follow the directive.

I'm curious what the solution is.
