+# Changelog
+
+## 4.0.0
+
+### Breaking Changes
+
+- **Minimum React 18.0.0** (was 16.2.0)
+- **Minimum React Native 0.73.0** (was 0.50.4)
+- **`react-native-fit-image` removed** - The default `image` render rule now uses React Native's built-in `<Image>` component. Users who need auto-sizing image behavior should provide a custom `image` render rule.
+- **`prop-types` removed** - Runtime prop validation is no longer performed. Use TypeScript for type checking.
+- **Class component replaced with function component** - `<Markdown>` is now a function component using hooks. Code relying on class instance methods or refs will break.
+- **`markdown-it` upgraded from ^8 to ^14** - Custom markdown-it plugins should verify compatibility.
+- **Package entry points changed** - `main` now points to `lib/commonjs/index.js`, `module` to `lib/module/index.js`, `types` to `lib/typescript/index.d.ts`.
+
+### New Features
+
+- Full TypeScript source with auto-generated type declarations
+- Exported types: `ASTNode`, `RenderFunction`, `RenderRules`, `MarkdownStyles`, `MarkdownProps`
+- ESM module output via react-native-builder-bob
+- Proper memoization using `useMemo` hooks for better rendering performance
+
+### Improvements
+
+- All source converted from JavaScript to TypeScript
+- Deprecated `componentWillMount` and `componentWillReceiveProps` replaced with hooks
+- Broken `PropTypes` import from `react` removed in AstRenderer
+- Unused `React` and `View` imports removed from parser
+- ESLint + Prettier configured
+- Jest test suite with 99 tests across 17 suites
+- Integration snapshot tests for comprehensive markdown rendering
+
+### Removed
+
+- `react-native-fit-image` dependency
+- `prop-types` dependency
+- `chokidar` and `fs-extra` dev dependencies
+- `bin/` build scripts (replaced by react-native-builder-bob)
+- `export.json` debug artifact
+- Hand-written `index.d.ts` (replaced by auto-generated types)
+- `.npmignore` (replaced by `files` field in package.json)
