Here’s a terse draft:

fast-agent 0.7.0

This release focuses on structured automation, cleaner configuration, and stronger runtime/export tooling.

Highlights

• Added fast-agent batch structured for JSONL/CSV batch jobs with JSON Schema or Pydantic schema output, resumable
  runs, sampling, per-row errors, telemetry, and summaries.
• Expanded structured-output support across providers, including JSON Schema loading, Pydantic schema models,
  structured_tools policies, and a fast-agent check structured-tools compatibility probe.
• Introduced plugin slash-command actions, allowing global or agent-scoped commands to be registered from config/cards
  and run in both TUI and ACP clients.
• Renamed the default config files to fast-agent.yaml and fast-agent.secrets.yaml, with new fast-agent home
  discovery via FAST_AGENT_HOME / --env.
• Added privacy-filtered session trace export using the optional privacy extra, including local model resolution/
  download and redaction summaries.
• Added xAI Responses support, including Grok 4.3 defaults and experimental websocket transport.
• Improved shell runtime behavior: inherited fast-agent environment, better idle timeout semantics, safer output
  draining, and head/tail truncation for large outputs.
• Added MCP Apps metadata support alongside existing Skybridge/OpenAI Apps SDK metadata.
• Added fast-agent model export to generate editable local model overlay manifests from catalog entries.
• Refreshed model aliases and catalog defaults for current OpenAI, Anthropic, Gemini, Grok, Kimi, MiniMax, GLM, and
  DeepSeek routes.

Migration Notes

• Prefer fast-agent.yaml and fast-agent.secrets.yaml. Legacy fastagent.config.yaml and fastagent.secrets.yaml
  are still recognized, but keeping multiple supported names in one directory is now treated as ambiguous.
• Config discovery now prefers the active fast-agent home, then the current working directory. Parent-directory walking
  is no longer the primary implicit discovery behavior.
• Use FAST_AGENT_HOME for the active environment directory. ENVIRONMENT_DIR remains as a legacy compatibility
  alias.
• Existing scaffolds, examples, and docs should be updated from fastagent.config.yaml to fast-agent.yaml.
• Privacy-filtered export requires installing the optional extra: fast-agent-mcp[privacy] or fast-agent-mcp[privacy- gpu].
• Consumers of exported Codex trace JSONL should note event naming changes from turn_started / turn_complete toward
  task_started / task_complete, with additional timing and token usage metadata.
• Some model aliases were updated or removed to track current provider catalogs. Pin explicit model names if you depend
  on old aliases.
• Structured-output calls with tools may now use provider/model-specific policies. Use ?structured_tools=always, ? structured_tools=defer, or ?structured_tools=no_tools when you need explicit behavior.
