January 2026 monthly summary for grafana/metrics-drilldown. Delivered comprehensive internationalization (i18n) enablement and code-quality automation, improving global reach and developer productivity. Implemented i18n infrastructure with Grafana-version aware resource loading, translations (en-US/es-ES), and a Crowdin-powered localization workflow. Migrated ESLint to a flat config and integrated @grafana/i18n rules to catch untranslated strings and top-level translations. Localized Trail breadcrumbs using t() with safe fallbacks and updated related tests. UI improvements include background task counters for breakdown panels and user-friendly, translated rule-filter tooltips. Updated routing dependencies (qs, @remix-run/router, react-router, react-router-dom) for security and compatibility, and stabilized E2E tests by ensuring i18n is available in the Playwright container. Fixed a translation-loading edge case when version is undefined, preventing runtime errors and improving CI reliability.
