Changelog

All notable changes to the Diff Checker Chrome extension.

v1.1.11 April 2026

Improved

  • Editor now uses the system monospace font (Cascadia Code on Windows, Menlo on macOS) — popup opens faster and works fully offline
  • No more network requests to Google Fonts when the extension opens

Fixed

  • Cursor and diff highlights could appear offset by several characters from the actual text — most visible on Microsoft Edge or behind a corporate proxy / tracking-prevention that blocked the font CDN
v1.1.10 April 2026

New

  • Configurable context lines around changes when "Show Diff Only" is enabled — pick 0, 1, 2, 3, or 5 lines via dropdown next to the button
  • Pure-diff mode: choose "0 lines" to hide all surrounding code and see only the changes

Improved

  • Default context line count is 3, matching Git and VS Code

Fixed

  • "Show Diff Only" button now activates correctly after pasting or typing text directly into the editor
v1.1.9 April 2026

New

  • Word wrap toggle in the toolbar

Improved

Fixed
