+Released: 2026-03-27
+
+### Highlights
+
+- Reworked the collected-data overview into a clearer split between KPI cards and a switchable treemap distribution.
+- Added a direct Earth entry on the dashboard and tightened several admin-side scrolling/layout behaviors.
+
+### Added
+
+- Added a dashboard quick-access card linking directly to `/earth`.
+- Added collected-data treemap switching between `按数据源` and `按类型`.
+- Added data-type-specific icons for the collected-data overview treemap.
+
+### Improved
+
+- Improved collected-data summary behavior so overview counts follow the active filters and search state.
+- Improved the collected-data treemap with square tiles, a wider default overview panel width, and narrower overview scrollbars.
+- Improved responsive behavior near the tablet breakpoint so the collected-data page can scroll instead of clipping the overview or crushing the table.
+
+### Fixed
+
+- Fixed the user-management table overflow issue by restoring `ant-table-body` to auto height for that page so the outer container no longer incorrectly takes over vertical scrolling.
+- Fixed overly wide scrollbar presentation in collected-data and related admin surfaces by aligning them with the slimmer in-app scrollbar style.
