 # Changelog

+## 2026-04-04 - 3.55.1 - fix(appui)
+replace hardcoded app UI theme colors with shared dees CSS variables
+
+- Standardizes app UI component styling on shared --dees-* theme tokens across app bar, menus, tabs, main content, and bottom bar
+- Removes remaining hardcoded light/dark color values in favor of centralized background, border, text, badge, tooltip, scrollbar, and accent variables
+
+## 2026-04-04 - 3.55.0 - feat(theme)
+centralize theme CSS tokens in theme defaults and add missing interactive color variables
+
+- Refactors theme CSS variables to derive light and dark values from the shared themeDefaults token map instead of hardcoded color literals.
+- Adjusts dark background token values so secondary and tertiary surfaces align more consistently with the dark UI palette.
+- Adds new theme variables for interactive states, focus ring, tooltip, link, code, selection, and scrollbar styling.
+
+## 2026-04-04 - 3.54.0 - feat(media)
+rename media tile components to thumbnail components and add shared thumbnail base exports
+
+- Replaces dees-tile-* media component exports and implementations with dees-thumbnail-* counterparts for audio, image, video, note, folder, and pdf previews.
+- Introduces a shared DeesThumbnailBase and shared thumbnail styles for consistent sizing, hover overlays, loading states, error states, and lazy-loading behavior.
+- Updates the media index to export the new thumbnail component modules.
+- Includes a small layout cleanup in dees-dataview-codebox by removing forced full-height and absolute grid positioning.
+
 ## 2026-04-03 - 3.53.0 - feat(dees-pdf-viewer)
 add configurable sidebar position support
