They translated 572 out of 1951 PO file strings, reaching 29.3% completion and enabling Polish-speaking users to access documentation in their native language. Ytwaltiyt utilized Weblate for translation management and Git-based collaboration, integrating updated UX strings to improve the onboarding and support experience. Their work focused on documentation, localization, and translation, laying the groundwork for broader internationalization efforts. While no bugs were fixed during this period, the feature delivered enhanced accessibility and supported future localization pipeline readiness.
