V3.4.2 — 2026-05-21
Fixed
- issue #31: Feishu card PATCH updates are now serialized per session so older card snapshots cannot land after newer content and cause thinking/answer text to flicker or roll back.
- Concurrent Hermes callback events now allocate per-message sequence numbers under a lock, preventing duplicate sequence ids that could make valid
thinking.delta/answer.deltachunks look stale.
Tests
- Added regression coverage for out-of-order PATCH completion and concurrent runtime sequence allocation.
