+## [1.0.0] - 2025-09-20
+
+### Changed
+
+- Migrated from `renderLink` patch to new `drawLinkPath` patch (`ExtraLinks.js`), compatible with ComfyUI frontend ≥ 1.27.1.
+- Updated link renderers to use `{x, y}` objects (`link.startPoint` / `link.endPoint`) instead of `[x, y]` arrays.
+- Patched `calculateCenterPoint` to align markers with custom paths.
+- Improved patching lifecycle: now waits for `app.canvas.linkRenderer.pathRenderer` before applying.
+- Preserved all extension settings (Enable, Shape, Radius, Offset, Curvature).
+
+### Breaking
+
+- **Requires ComfyUI frontend ≥ 1.27.1.**
+- ExtraLinks is no longer compatible with earlier frontend builds. Users on older ComfyUI must stay on **ExtraLinks v0.0.2**.
+
+---
+
+## [0.0.2] - 2025-07-15
+
+### Added
+
+- Initial implementation of custom link shapes (`Curved`, `Rounded`).
+- Configurable Radius, Offset, and Curvature.
+- Toggle Enable/Disable from settings panel.
+- Basic marker rendering at link midpoints.
