0.6.8 (2026-10-14)

Bug Fixes

• Disconnect, chat close, inactivity, and session-capacity retirement let accepted turns finish and persist their model, tool, and handoff results before exit. Reconnecting cancels pending retirement; explicit Stop remains effective. Cancelled public calls settle through a terminal error event and through the history API.
• With Relay 0.3.17 and Session 0.6.8 installed, affected users can remove the local backend wind-down and cancellation-settlement patches after checking the published versions in their environment.
• harden tool controls and persisted handoffs (#61) (e8cce7c)
• session: drain accepted work before lifecycle retirement (#65) (7b7e2b4)

Dependencies

• Require Agent 0.5.4 and LLM 0.5.7 so Stop during prompt construction prevents another provider call and positional conversation messages retain their order.
