Zot vs Zot6 protocol
Zot6 is a more recent version of Zot and it's my understanding that these two are not compatible. Osada and Zap support Zot6 while Hubzilla supports Zot (and only Zot6 internally). My suggestion would be to add this distinction. More information on Zot and Zot6: https://medium.com/we-distribute/got-zot-mike-macgirvin-45287601ff19
