Thiago, I'm guessing you created the apidocs after bumping the version to 5.6.0 on your desktop. That might explain why the published apidocs pages all say 5.6.0 at the top. Not a major problem, just wanted to let you know.
Also, there's an extraneous directory tree of yours in there left over from Sep 2019: https://tapestry.apache.org/5.4.5/coffeescript/home/thiago/ Again, not causing any real harm there.
