 - Fixed [frontend/public/earth/js/tv.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/tv.js) by refactoring repeated iframe/video reset paths into shared helpers, so TV source switching, empty-state fallback, and playback retry handling no longer duplicate cleanup logic across multiple branches.
 
+## 0.26.2
+
+Released: 2026-04-12
+
+### Highlights
+
+- Stabilized the new reusable scrollbar work by restoring reliable sidebar visibility and extending the same floating scrollbar language to the Data Sources tables without letting scrollbars squeeze layout width or regress the console navigation.
+
+### Added
+
+- Added [frontend/src/components/Scrollbar/ScrollbarOverlay.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/ScrollbarOverlay.tsx) as an overlay variant that binds to existing scroll containers such as Ant Table bodies, so heavy data grids can adopt the new scrollbar visuals without replacing their built-in scrolling mechanics.
+
+### Improved
+
+- Improved [frontend/src/components/Scrollbar/Scrollbar.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/Scrollbar.tsx), [frontend/src/components/AppLayout/AppLayout.tsx](/home/ray/dev/linkong/planet/frontend/src/components/AppLayout/AppLayout.tsx), and [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by reverting the sidebar to a reliable vertical-first scrollbar path, then reintroducing automatic dual-axis support with independent floating tracks that no longer hide the thumb when only the sidebar needs vertical scrolling.
+
+### Fixed
+
+- Fixed [frontend/src/pages/DataSources/DataSources.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/DataSources/DataSources.tsx) and [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) so the built-in and custom datasource tables now use the new overlay scrollbar instead of native table scrollbars, keeping horizontal and vertical scrolling available without changing Ant Table’s internal layout behavior.
