Yesterday, there were 2 instances of failing to fetch data which could be resolved with "dht findprovs" which I think is because my node couldn't find the hosting peer "dht findpeer".
In both cases, the data fetch started to work after about 30 minutes. I suspect that this is just an issue of a newly-started node taking a while to discover the nooks and crannies of the network. Whatever it is, it is nice to see that it eventually worked.

In other news, I think all of the on-IPFS v2 changes are in good shape for version 3.1. This won't enable those features but will at least mean that the system can understand them. This will avoid a lock-step break of Cacophony usage over the 3.1-4.0 upgrade (since 4.0 is where the new features will be made live).
Aside from some tightening of the data schema, the big changes in this version of the data model are to enable non-breaking extensibility for later features while also enabling a sort of "reply to" feature, for normal posts. This will allow for the emergence of discussion threads across the system so I am quite interested in this.

Probably start with 3.1 pre-releases soon,
Jeff.
