 # Bill Tracker — Changelog
 
+## v0.23.3
+
+### Changed
+- **Replaced native `confirm()` with shadcn/ui AlertDialog** — TrackerPage (mark as paid) and DataPage (import confirmation) now use themed, accessible AlertDialog components instead of browser-native `confirm()` dialogs. Consistent with the app's design system and supports dark/light mode.
+- **STRUCTURE.md tech stack corrected** — Updated from "Next.js App Router" to the actual stack (Vite + React + Tailwind + shadcn/ui + Sonner)
+
 ## v0.23.2
