+## 0.8.9 (2026-06-15)
+
+### 🩹 Fixes
+
+- **host-container:** a TruApi-routed transaction broadcast no longer abandons itself — the chain connection is now held for the lifetime of the broadcast (until a matching `transaction_v1_stop`) instead of being torn down immediately, so transactions are actually included. Duplicate/unknown stops are idempotent no-ops.
+
+### ❤️ Thank You
