 ### Fixes
 
+- Web UI: make chat refresh smoothly scroll to the latest messages and suppress new-messages badge flash during manual refresh.
 - Cron: route text-only isolated agent announces through the shared subagent announce flow; add exponential backoff for repeated errors; preserve future `nextRunAtMs` on restart; include current-boundary schedule matches; prevent stale threadId reuse across targets; and add per-job execution timeout. (#11641) Thanks @tyler6204.
 - Subagents: stabilize announce timing, preserve compaction metrics across retries, clamp overflow-prone long timeouts, and cap impossible context usage token totals. (#11551) Thanks @tyler6204.
 - Agents: recover from context overflow caused by oversized tool results (pre-emptive capping + fallback truncation). (#11579) Thanks @tyler6204.
