This tool is only useful if you know what XEPs actually matter, which is not most people (nor expected to be!).

https://xmpp.org/software/ is a better resource for most people, as it provides the compliance filters (each software entry being either "core" or "advanced" in different categories, depending on e.g. whether you want a web/mobile client, etc.).

As you can see, Dino is pretty up to date: https://xmpp.org/software/dino/

Conversations, for comparison: https://xmpp.org/software/conversations/
