+# Changelog
+
+## 2.0.0-beta.9
+
+### Added
+
+- Full SwiftUI-idiomatic modifier API:
+  - `chartData`, `chartXRange`, `chartYRange`
+  - `chartGridLines`, `chartGridStroke`, `chartGridBaseline`
+  - `chartXAxisLabels`, `chartYAxisLabels`, `chartAxisFont`, `chartAxisColor`
+  - `chartLineWidth`, `chartLineBackground`, `chartLineMarks`, `chartLineStyle`, `chartLineAnimation`
+  - `chartInteractionValue`
+- Immutable chart configuration structs and environment-key-based composition.
+- Updated docs/examples and generated showcase app.
+
+### Changed
+
+- Major clean break from mutating chain APIs.
+- Chart style/data/range/axis/grid/line configs are now modifier-driven and value-based.
+
+### Fixed
+
+- Removed required `@EnvironmentObject` interaction dependency for basic chart rendering paths.
+- Existing regression and smoke tests remain green after API shift.
+
+### Migration
+
+- See `MIGRATION.md` for full old-to-new mapping.
