28 Commits • 10 Features
Feb 1, 2026February 2026 (2026-02) focused on stabilizing Explore experiences, accelerating rendering performance, and tightening code quality while delivering targeted UX improvements and business-value releases. Key outcomes include stability fixes for imagery loading on Explore (handling missing imagery, initial load, and end-of-street cases) and a reduction in unnecessary canvas rerenders, along with race-condition fixes. Tutorial completion was fixed and labeling reliability improved. The Explore notification system was overhauled and sign-up translations updated to improve onboarding. Infra3d integration was advanced with backend formatting and cleanup, complemented by targeted codebase simplifications. Additional performance and release-quality work included speed-limit prefetch optimization, a grunt tooling stability fix, and a version bump to 11.0.0, plus Pedestrian Signal tag updates for Zurich servers to support regional deployments. Overall, these changes reduce user-support needs, improve map exploration reliability, and enable faster iteration cycles for labeling workflows.

Apr 1, 2025April 2025 delivered a comprehensive Admin UI/data migration overhaul on the SidewalkWebpage, enabling a loaded Admin page with migrated Overview and Activities, populated with key analytics stats and user metrics. Frontend polish included a Bootstrap date picker upgrade, removal of unnecessary JS mime types, and code cleanups, reducing technical debt and improving maintainability. Major architectural and performance improvements encompassed clustering code migrations with spatial-index optimizations, nightly clustering, and caching the PS version across pages to improve consistency and response times. Multiple migrations across UI, API, and data models enhanced type safety, API reliability, and admin UX (TimeInterval enum, Slick-based Street Distance query, Admin UI tab migrations for Labels/Users/Teams, and Admin Analytics graph migrations). These changes collectively increase business value by delivering faster admin workflows, more accurate analytics, and a more scalable, maintainable codebase.
