# Week of May 11, 2026

> PDF viewer, find bar, image attachments in chat, drag-and-drop, and more.

## New features

* **PDF and binary file preview.** Binary files now open in a built-in viewer
  instead of trying to render as text. PDFs get a full reader with paging,
  zoom, and search. See [Tabs](/tour/tabs).
* **Floating Preview button.** When the active tab matches a hook that
  produces an output artifact (PDF, HTML, SVG, …), a **Preview** button
  appears in the top-right of the editor. Click it to open a live-reloading
  popup that refreshes every time the hook runs. See
  [Live preview](/automation/preview).
* **Find bar.** Press `Cmd/Ctrl+F` to open an in-editor find bar scoped to
  the active tab. Step through matches with `Enter` / `Shift+Enter`, and
  toggle case sensitivity. See [Keyboard shortcuts](/reference/shortcuts).
* **Image attachments in chat.** Drop or paste PNG / JPEG / GIF / WebP
  images into the chat panel to send them to the agent alongside your
  message. Useful for sharing screenshots, figures, or reference images.
  See [Steering the agent](/agent/steering-the-agent).
* **Drag files in from Finder.** Drag files from your filesystem onto the
  file tree (into any folder) or onto the tab bar to copy them into the
  workspace and open them. See [Tabs](/tour/tabs).
* **Session viewer.** A new viewer lets you replay an agent session
  end-to-end — tool calls, intermediate messages, and edits — to see
  exactly what the agent did. See [Observability](/agent/observability).

## Updates

* **Outline pane lists pending edits and comments across all tabs.** The
  outline now surfaces every tab with a pending review round or unseen
  comment, and clicking an item jumps you straight to that tab and
  location. See [Reviewing edits](/agent/reviewing-edits) and
  [Comments](/agent/comments).
* **Pending tabs float next to the active tab.** Tabs with pending agent
  edits are pulled to sit immediately after the active tab so they stay
  visible without scrolling the tab bar.
* **Accept feedback in the editor.** Accepting an agent edit now flashes
  a soft halo on the accepted text for a moment, so it's clear what just
  landed.
* **Agent plan modal renders markdown.** Plans the agent proposes now
  render with bullets, numbered steps, headings, bold, and inline code
  instead of as a wall of plaintext. See
  [Delegating tasks](/agent/delegating-tasks).
* **Sign in with a Claude Code OAuth token.** DocWriter now also accepts
  `CLAUDE_CODE_OAUTH_TOKEN` as a credential source, alongside
  `ANTHROPIC_API_KEY`, `--api-key`, and `claude login`. See
  [Install](/install).

## Bug fixes

* The agent's `Read` tool no longer tries to read binary images as text
  and instead returns a clear error explaining how to attach the image
  via the chat panel.
* Various stability fixes across the editor and chat panel.
