About Arize Phoenix
Phoenix ships near-daily, steadily wiring evals and agent behavior into its traces.
Phoenix releases the server, client, CLI and MCP packages almost daily, with many entries being dependency bumps. Substantive changes cluster around tracing: eval results in the trace tree, a new DECISION span kind, and bash tool spans flagged as errors on non-zero exits. The TypeScript client keeps gaining project and prompt management helpers.
