Diffsmith Changelog

Walkthroughs. Ask your agent to walk you through a feature, a bug, or the change it just made, and it writes a numbered tour of the code into Diffsmith: each step anchored to a real line, in any file, at any commit. You step through them one at a time and reply to any step to ask a follow-up. More about walkthroughs.

Changed images now open in a proper comparison view, with side-by-side, overlay, swipe and pixel-difference modes. The difference mode rings the regions that actually changed, and both sides zoom and pan together. Images tracked in Git LFS resolve from your local cache instead of failing to display.

You can now comment on a whole file when there’s no line to point at, which is the only sensible option for an image or another binary, and works on any file from its diff header.

Comment text has its own size setting in Appearance, separate from the code font, and the default is a little larger than it was. Fenced code blocks in comments keep their line breaks, so a pasted stack trace is readable.

Also: a new View menu item to collapse expanded context (⌥⌘K), expansions fold back when you switch comparison, and a refresh no longer throws the cursor to the start of a comment you’re typing.

Reviews are no longer limited to uncommitted work. You can now point a repository at a past commit, a range of commits, everything since a given commit, or a diff between two branches, and review it exactly the way you review your working tree.

If you’re using the MCP server, your agent understands when its edits won’t show up because of the comparison you’re reviewing, and a button appears to take you to the right place.

This version also cuts the number of tokens your agent spends talking to Diffsmith over MCP.

Search is here. Press Command + F to search the file you have open, or Command + Shift + F to search across every file in the diff. Searches cover the whole file, not just the changed hunks.

Bug fixes and minor improvements.
