Project Health

Interest in Ursa is growing with 10+ attendees at the biweekly meeting with many more asking questions on the #ursa channel in Rocket.Chat and the ursa mailing list. Version 0.1 release is expected by end of March.


Biggest concern right now is getting a CI/CD pipeline going. Sovrin has created their own for Ursa for testing the features pertinent to them. Still no word on a preferred location for artifact delivery either.


First release since incubation is expected by end of March.
