The project has undergone a full rewrite! (This happened a while ago but I never released it)
There were many fixes and API simplifications, as well as the following major changes:

Backend

The provided backend now uses native_db - a simple embedded database using the redb KV store. This change has the benefit of being much more lightweight than the previous implementation.

DIDs

DWNs now use the new xdid crate for DID resolution. This new library was designed to be smaller and simpler than other DID libraries. Currently the did:key and did:web methods are implemented.
