WebberZone Code Block Highlighting

1.2.1

Release Date – 20 August 2026

• Improvement: Setting defaults are now resolved from a single lightweight list instead of building every settings field, so reading an option early in the page load no longer risks a “translation loading triggered too early” notice.
• Fix: Fixed settings on a multisite network reading another site’s values in the same request after a switch_to_blog() call.
• Fix: Fixed the settings wizard silently dropping repeater field rows on save.

1.2.0

Release Date – 6 August 2026

Release post: https://webberzone.com/announcements/code-block-highlighting-v1-2-0/

• New: File name tab. The file name set on a block now renders as an editor-style tab above the code block, coloured to match the active Prism theme. Works identically in client-side and server-side modes.
• New: “File Name Style” setting to choose between the new tab and the previous toolbar label.
• New: wzcbh_file_tab_html filter to customise the file name tab markup.
• New: Download snippet button. A “Download” button now appears next to “Copy” in the code block toolbar, saving the snippet as a file named after the block’s file name, or snippet.{ext} derived from its language. Enabled by default; it can be turned off globally with the new “Download Snippet” setting, or per block from the “Download button” control in the block sidebar.
• New: wzcbh_download_extensions filter to customise the language-to-file-extension map used for downloads.
• Fix: File names saved by the older Code Syntax Block plugin (stored as a title attribute on the <pre>) are now displayed on the frontend without needing the post to be re-saved.
• Fix: The block editor canvas no longer picked up background: window from the forced-colors media query in several themes, which left the editor code block unstyled.

1.1.0

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.
