Agno's March 2026 release (v2.5.9) standardizes the Knowledge Protocol across all agents and expands the event system with new events for model requests, compression, and memory updates. New run-level parameters in Workflows enable metadata propagation and dependency injection across all downstream agents in a graph — solving a common production problem where workflow context couldn't flow to sub-agents. Positions Agno as the structured alternative to LangGraph for teams preferring Pythonic primitives.
