• Undo for everything: closing duplicates, archiving, organizing and switching to an already-open tab can all be undone (notice, palette, or Alt+Shift+U).
• Preview before applying: see proposed groups (and rename them) or the tabs that would be closed before anything changes.
• Duplicate handling now only applies to newly opened tabs and never closes different pages on the same site; closed duplicates are archived.
• New tabs join a matching tab group automatically (can be turned off).
• Site rules: sites to never close, and sites to keep to one tab.
• Choose after how many days unused tabs are archived, with optional automatic archiving.
• Welcome page, tab count on the toolbar icon, light and dark theme, download progress for the on-device AI model.
• The on-device AI runtime is now bundled instead of loaded from a CDN.
