   "notes": "### Added\n- Added manual pane labels through `herdr pane rename`, the `pane.rename` socket API, an optional `keys.rename_pane` binding, and the right-click pane menu.\n- Added `ui.show_agent_labels_on_pane_borders`, which can show detected or reported agent names in split pane borders when no manual pane label is set.\n- Added `herdr integration status [--outdated-only]` so installed agent integrations can be checked for legacy or outdated versions.\n- Added an optional `keys.open_notification_target` binding for jumping to the pane behind the current notification.\n- Added optional `keys.previous_agent` and `keys.next_agent` bindings for cycling through sidebar agent entries.\n\n### Changed\n- Scrolling over the tab bar now switches tabs directly, including overflowing tab bars.\n\n### Fixed\n- Indexed terminal palette colors now render correctly for 256-color terminal apps.\n- Hook-based agent integrations now reject stale out-of-order reports and base notifications on effective agent state, reducing duplicate or stuck state changes.\n- Background tabs now resize when the outer terminal size changes, preventing stale pane dimensions when switching back to them.\n- Client shutdown now drains queued control messages more reliably.\n- Pane cursors are now hidden while scrolled back, and omitted while the mobile switcher is open.\n- Mobile agent switcher entries now include tab context, making agents easier to identify on narrow terminals.\n- macOS foreground job detection now uses process groups, improving agent state tracking for foreground commands.\n- Remote SSH no longer fails before connecting when macOS temporary bridge socket paths exceed Unix socket length limits. (#103, thanks @moonsphere)\n- Nix-wrapped agent commands are now detected by their underlying agent entrypoint.\n- Pane renames made through the socket API now rerender immediately.",
