AddedAdded a release notes button in Settings > Updates that opens the latest GitHub release in the user's browser
AddedAdded pane-native drag and drop for Agents sidebar threads, so chats and subagents can open in panes, move existing chat tabs, or create split panes
AddedAdded a floating drag preview for Agents sidebar threads with the thread title, runtime, and active or error state while dragging
ChangedChanged file-tree drag behavior so dropping existing notes, PDFs, and files onto editor panes opens them as tabs instead of inserting embed markup
ChangedChanged file-tree and external file drops to use pane-native targeting for pane centers, tab strips, and pane edges, while AI composer drops still attach to chat
ChangedPolished the chat composer expand and collapse button with clearer diagonal arrow directions and a subtle hover highlight
FixedFixed AI chat tabs restored from saved history so persisted identifiers no longer leak into live runtime commands
FixedFixed workspace tab dragging so file-attachment drag events emitted by tabs no longer clear the pane split or drop preview
