I've been working on implementing XEP-0496 (Pubsub Node Relationships) and XEP-0499 (Pubsub Extended Discovery) in Libervia to allow a tree-like hierarchy in pubsub nodes.
This is a big deal for many reasons, from better organisation to features which become possible (think about file sharing, forums, etc).

1. A screen capture of Libervia CLI in a terminal showing a tree of pubsub nodes on the work-in-progress email gateway. The tree show a root node for forums, then the identifiers of 2 mailing lists converted from email to XMPP (`membes.xmpp.org` and `standards.xmpp.org`). This is a test instance, so only 3 comment nodes are seen for the `standards.xmpp.org` mailing list. We can read this: ``` % li pubsub list -cs email.tazar3.int urn:xmpp:forum:0 ├── members.xmpp.org └── standards.xmpp.org ├── urn:xmpp:microblog:0:comments/685041b7.050a0220.3aa7c3.52e0@mx.google.com ├── urn:xmpp:microblog:0:comments/685041ba.050a0220.3aa7c3.52e1@mx.google.com └── urn:xmpp:microblog:0:comments/91ca1f6a-489a-4f1c-ab34-a7583d97e21e@movim.eu ```
