so-fancy/diff-so-fancy v1.4.12

on GitHub

New Features

• sem integration: First-class integration with the sem tool to show contextual commit info.
• 24-bit color support: Replaced color logic with a new color() function supporting 24-bit colors
• Human-readable dates: Date: lines now show a friendly human time

Bug Fixes

• Plain diff coloring: Plain (diff -u) input is now correctly colorized when stripLeadingSymbols is off.
• Manual coloring: Smarter detection of when to enable manual coloring mode, and a fix so it works on short diffs.
• Patch-mode line mismatch: Fixed line counts on added/deleted files in --patch mode.
• Large diff chunks: Diff chunks are split on commit and remaining lines are preserved when chunks are too large.

Security

• Output sanitization: Basic sanitization is now applied before writing anything to the screen, to avoid echoing control/escape sequences.

Encoding & Rendering

• UTF-8 everywhere: STDIN/STDOUT forced to UTF-8. It's 2026, and everything is UTF-8 now.
• Smarter box drawing: Ruler/box drawing is now content-aware.

CI / Build / Dependencies

• CI now dynamically syncs package.json version before npm publish.
• Bumped actions/checkout from 6 -> 7.

Documentation

• README updates, spelling fixes, and a corrected link to the sem project.
