During March 2026, Loeffler updated the API documentation in the TYPO3-Documentation/TYPO3CMS-Reference-CoreApi repository to reflect recent file renaming, focusing on the UserPassLoginForm template reference. Using reStructuredText and technical writing skills, Loeffler ensured that all documentation references matched the current repository state, reducing confusion for developers and streamlining onboarding. The work included correcting a broken link in LoginProvider.rst, which maintained the accuracy of the API overview. This targeted documentation update did not involve bug fixes or new features beyond the reference alignment, but it improved maintainability and helped prevent future discrepancies between code and documentation.
