November 2025: Key documentation enhancement in TYPO3CMS-Reference-CoreApi to enable Crowdin translation mass approvals. Delivered API workflow documentation and a PHP 8.4+ script for programmatic approvals, with usage examples (all languages and single language), security considerations, and a web-interface alternative. Updated the extension integration guide and improved formatting (anchors, sentence-case headlines) to improve discoverability and reduce manual translation effort. This work reduces manual approval steps, accelerates localization cycles, and demonstrates strong collaboration (co-authored with Lina Wolf, PR #6228).
