Agno 3.1.5–3.1.6 adds repository sandboxes and session-aware evals

v3.1.5 was published at 2026-10-19T11:53:23Z. v3.1.6 was published at 2026-10-19T13:44:23Z. This summary follows the maintainers’ release notes.

What changed

• In 3.1.5, sandboxed ClaudeAgent and CodexAgent sessions can start from a Repository configuration. The first turn pins a commit; later turns retain the pin and edits through warm reuse and checkpoint restoration.
• S3CheckpointStore stores content-addressed checkpoints in S3-compatible object storage. open_run_checkpoint exposes the archive a completed run committed.
• Schedules without a cron expression run only when triggered. External ClaudeAgent and CodexAgent instances can join the Registry.
• Version 3.1.6 adds session_id, user_id, session_state, dependencies, metadata and knowledge_filters to evaluation cases. Cases sharing a session_id run as consecutive turns, and Message inputs can attach images or files.

Before upgrading

The 3.1.5 notes say cross-replica streaming and cancellation still require Redis, even though sandbox API runs can use a Postgres durable queue without it. Configure private-repository credentials in the sandbox environment rather than embedding them in source.
