v3.0.0

3.0.0 (2025-05-13)

Highlights

• Please note: We no longer support MediaWiki versions 1.39-1.42.
• We've improved caching for <tabbertransclude> API requests! Your pages should load faster now as requests check edge and parser cache before accessing the database.
• Tabpanel IDs in URLs now follow the same format as MediaWiki page headings (like duplicated_2), making them more consistent.
• We've renamed $wgTabberNeueUseLegacyTabIds to the clearer $wgTabberNeueAddTabPrefix. This setting adds the tabber- prefix to tabpanel IDs to prevent conflicts with MediaWiki page headings and is enabled by default.
• Since we've updated the HTML structure, we strongly recommend purging pages that use Tabber if you have parser cache enabled.
