Jun 1, 2025June 2025 (mbta/dotcom) delivered updates across content, UI, privacy, and infra, reinforcing content freshness, accessibility, reliability, and maintainability. Key features included a new media-relations block on the News page with adjusted layout, an auto-refresh for juxtapose iframes to keep content current, and multiple UI/timeliness improvements. The alerts system was hardened for accurate current-status displays, future alerts were filtered, and access-state handling was added. Cache keys now ignore query parameters to share cache entries efficiently. Privacy controls were tightened by removing Informizely data from Sentry and CSP, addressing privacy and cost concerns. Maintenance and infra work modernized dependencies and container builds, and transit data displays were updated (Orange Line peak frequency and Maps UI). Accessibility enhancements (ferry stop accessibility and responsive timetable UI) and a discrimination-complaints right rail were added to improve customer support. These changes improved business value by delivering fresher content, faster responses, better compliance and security posture, and more maintainable systems.

Feb 1, 2025February 2025 was focused on delivering user-centric features, stabilizing multilingual UX, improving developer productivity, and strengthening data/monitoring capabilities across mbta/dotcom. Key work delivered locale-preserving language handling in MyCharlie, clarified navigation for Charlie Service Center, and reduced UI clutter by removing banners. The team introduced local component development tooling, added robust DateTime utilities with DST handling, and expanded schedule data with stop_headsign support. Planned disruptions logic was implemented and exposed in the system status UI, with groundwork for service-range grouping. Several reliability improvements included an event download link encoding fix and subdomain noindex to prevent internal environment indexing. These efforts collectively enhance business value through improved user experience, faster development cycles, and clearer operational visibility.
