Upgrade Guide

From 0.1.0 to 0.2.0

No breaking changes. All 0.1.0 conformant implementations remain conformant.

New optional features you can adopt:

1. Add agent:AgentDescriptionService to profile for ANP discovery
2. Add agent:memoryType to memory episodes for taxonomy classification
3. Add agent:embeddingModel to document embedding sources
4. Update signature verification to use RDFC-1.0 canonicalization
