+# 0.2.60 — 2026-06-21
+
+## Features
+
+- **/resume** now shows sessions from your current working directory's repo at the top of the list.
+- **Too-wide Mermaid diagrams** now show a hint below the fallback box pointing to the Open Image button.
+- **Cancel behavior for running subagents** can now be set to always stop or always continue in config.toml.
+
+## Bug Fixes
+
+- **Compaction** no longer hangs indefinitely when the summarizer stream stalls after the server has finished.
+- **Slash command completion** now shows consistent suggestions and remembers recently used commands.
+- **Queued prompts** now reappear reliably after deleting the last item and re-queuing.
+- **Headless sessions** no longer produce authentication error noise from unauthenticated MCP servers.
+- **Mermaid flowchart labels** with long identifiers are now kept whole instead of being cut mid-word.
+- **Cmd+Backspace** now deletes only from the cursor to the start of the line instead of clearing the whole prompt.
+- **Inline Mermaid previews** now break long identifiers at word boundaries instead of mid-segment.
+- **Signed git commits** no longer corrupt the TUI by letting pinentry draw over the screen.
+- **Arrow keys** now move the prompt cursor or open history while a /btw answer panel is visible.
+- **Long option descriptions** in question prompts now expand fully when the row is focused.
+
+## Performance
+
+- **Large MCP tool results** are now truncated inline and saved to disk to avoid unnecessary context compaction.
