The Undertow documentation page seems pretty stale: the latest documentation is only for v2.1.0 (apparently from April 2020!), but on Maven Central the latest version is v2.3.10.Final. The GitHub page doesn't seem to have any more recent documentation. I saw that the links to an offline ZIP documentation archive mentions undertow-docs-2.1.0.zip, so I thought maybe that the latest docs would be published on Maven Central, but a search there for undertow-docs yields nothing.
Where can I find the latest documentation for Undertow, e.g. for v2.3.10.Final?
