 ## Release Notes
 
+### 0.131.6 - 2026-05-22
+
+- Add the first beta version of agent-view: `codex agents` can inspect saved sessions offline, and the TUI session browser can open from the composer with Left arrow.
+- Render the agent-view session browser as a full-screen overlay with grouped session rows, peek preview, delete confirmation, resume, and start-new-session flows.
+- Mark agent-view as beta in this release: the core browsing/resume workflow is available, but UI polish and interaction details may still change.
+- Fix the 0.131 merge regression where standalone `xhigh`, `ultra`, or `ulw` markers no longer submitted the current query with `xhigh` reasoning.
+- Show the per-turn xhigh override in `model-with-reasoning` status-line output while that foreground turn is pending or running, without mutating persistent session defaults.
+- Keep per-turn effort override state across thread switch capture/restore.
+- Fix background task status-line drift so `/ps` and the footer agree when background terminals or subagents start, finish, or are cleared.
+- Preserve Zellij pane scroll behavior by rendering TUI inline under Zellij instead of trapping pane scroll in the alt screen.
+- Tighten subagent spawning guidance around contract-first delegation and quota-aware cleanup.
+
 ### 0.131.5 - 2026-05-21
 
 - Show renamed session identity directly in the chat composer border with a `Session: <name>` marker.
