v2.0.0

v2.0.0

Features

• GitHub Gist URL support — paste a gist.github.com/user/id URL to load diffs directly from GitHub Gists (single-file, with truncation handling)
• URL hash size warning — diffs too large to share via URL now show a warning instead of silently creating broken links

Improvements

• SRI integrity hashes on dynamically loaded highlight.js theme CSS (closes the last CDN integrity gap)
• Clipboard fallback (execCommand) for tutorial copy buttons and share URL copy on non-HTTPS contexts
• Specific error message for GitHub API rate limit (403) responses

v1.9.0

v1.9.0

Features

• File search filter — filter input in sidebar filters files by path in real-time, hiding non-matching files in both the sidebar tree and the diff/tutorial view

• Context-aware export filenames — HTML exports use diff.html / tutorial.html, or diff-filtered.html / tutorial-filtered.html when a filter is active
• Footer — links to the GitHub repository

Improvements
