Nested groups—and a more complete Arc import
Both releases support tab groups nested up to eight levels deep, plus a choice about whether links open new tabs inside groups. Arc imports now include unpinned tabs alongside Favorites and Pinned Tabs on Windows as well as Mac. That makes the migration improvement broader than a Mac-only reading might suggest.
For anyone considering a move, the sensible approach is to compare the imported workspace with the original before retiring it. More complete tab importing is useful; it should not be mistaken for a promise that every browser setting transfers.
Office files enter Chat; Figma has a platform caveat
Users on either platform can attach Word, Excel, and PowerPoint files to Chat for summaries, questions, and key points. The release notes describe document analysis—not Office-file editing—and do not specify file-size limits or supported extensions.
Figma account connections now support searching Design files, FigJam boards, and Slides, plus catching up on comments and mentions. Only the Mac changelog explicitly documents creation and editing, including filling a Slides template and converting a conversation into a FigJam diagram. Windows users should not assume those examples apply to their release.
For workplace use, treat summaries as an aid rather than the final authority: check consequential conclusions against the original document and confirm organizational approval before attaching sensitive files.
Windows gets more useful previews
Windows 1.6.0 adds several practical conveniences:
- Calendar previews offer event access and meeting joining.
- Morning Brief previews show scrollable, read-only checklists.
- Collapsed-group previews expose tabs and nested groups.
- Split-tab previews display every pane.
- Optional daily cleanup handles inactive tabs.
- Chat can save websites as PDFs.
- Dragging the sidebar or address-bar space supports Windows snapping.
The changelog also explicitly lists Teams Morning Brief support, a useful addition for Microsoft-centered workflows.
Mac users receive a separate authentication improvement: Dia handles sign-in requests from some Mac apps that previously opened Safari. “Some” matters; this is not a universal authentication fix.
The practical verdict
The strongest reason to evaluate this release is the combination of organization and fewer interruptions—not simply another place to ask an AI question. Nested groups and richer previews provide a concrete workflow to test. Whether they make Dia a better daily browser remains a hands-on judgment; these release notes establish shipped features, not measured performance gains.
