WebberZone Code Block Highlighting

1.1.0 (10 June 2026)

Release Date – 10 June 2026

Release post: https://webberzone.com/announcements/code-block-highlighting-v1-1-0/

• New: Server-side highlighting mode powered by highlight.php — syntax is pre-rendered on the server with no JavaScript required for highlighting.
• New: All 21 Prism themes work identically in both client-side and server-side modes. Server mode now outputs Prism-compatible token classes and loads the same theme CSS, so switching modes produces no visual difference.
• New: Added “Plain Text” language option to the language picker. Renders with Prism theme styling but no syntax highlighting.
• Fix: Duplicate language-* class on <code> elements in client mode when the saved block HTML already carried the class.
