+
+## [2.0.0] - 2026-07-12
+
+### Added
+
+- A two-layer component API that keeps the edge and ground shadow fixed while the cap moves.
+- JaydenART green and brown variants with documented CSS custom properties.
+- Keyboard focus, disabled, reduced-motion, forced-colors, and touch interaction states.
+- A responsive, dependency-free live demo with a strict Content Security Policy.
+- Deterministic contract tests and CI on Node.js 20, 22, and 24.
+- Contributing, security, and release documentation.
+
+### Changed
+
+- The live demo uses semantic HTML, local stylesheets, responsive layout, and stable press geometry.
+- The README documents the component structure, customization API, accessibility behavior, and development checks.
+
+### Fixed
+
+- Pressing the modern component no longer moves the base or changes layout dimensions.
+- Keyboard focus is visible instead of being removed.
+- The demo no longer depends on an external background image or inline JavaScript.
+
+### Compatibility
+
+- The original `.JayBrown` single-element class remains available for existing markup.
+
+[2.0.0]: https://github.com/JaydenART/JaydenART_Realistic_3D_CSS_Button/releases/tag/v2.0.0
