Sep 1, 2025

September 2025 monthly summary focused on delivering migration-ready documentation for translation management, strengthening terminology governance, and introducing a deprecation path to the core translation system. The work is designed to reduce migration risk for customers, accelerate adoption of the core translation features, and improve maintenance through clearer guidance and better link integrity across documentation. Impact highlights include: a migration-focused documentation suite for moving translation handling from the Language Pack plugin to core translation management (6.7.3, with 6.8 deprecation), comprehensive terminology and guidance updates for base/fallback languages, and a new deprecation banner in Language Pack Settings with styling, unit tests, and a refactor to simplify rendering. These efforts reduce customer friction, enable faster onboarding for new installations, and provide a consistent reference point for developers and partners. Technologies and skills demonstrated include documentation best practices, translation system domain knowledge, front-end styling with SCSS, unit testing, and cross-repository collaboration to align docs with code changes.
