Prototype Version History
Ouroboros is still in an early proof-of-concept prototype phase. Versions 0.x.y have no forward nor backward compatibility. We bump minor version with API or protocol changes. Within a minor version, different patch levels should be compatible (no guarantees).
Once the functionality has reached a minimal critical mass, and a sufficient degree of software stability has been achieved, a version 1.0.0 will be released with the intention to maintain backwards compatibility from that point. This is still many (man)years off.
This page summarizes the progress and the plans for the next prototype (minor) version. For a summary of the current implementation state, see our status page.
