v4.1.0

New Features

• onLinkPress prop — custom link press handler, falls back to Linking.openURL()
• mergeStyle prop (default true) — deep-merge custom styles with defaults per key instead of replacing entire style objects
• debugPrintTree prop — log the AST tree structure to console for debugging
• maxTopLevelChildren + topLevelMaxExceededItem props — preview mode to limit rendered top-level children
• allowedImageHandlers + defaultImageHandler props — validate image URL schemes before rendering
• Image accessibility — accessibilityLabel and accessible set from image alt text

Bug Fixes

• Hardbreak renders as <Text>{'\n'}</Text> instead of <View> — fixes crash on Android when hardbreak is inside a Text node
• Code block and fence rules trim trailing newline added by markdown-it parser
• Ordered list respects the start attribute (e.g. 57. foo now renders as 57 instead of 1)

Internal

• RenderFunction type extended with ...args: unknown[] rest parameter for backward-compatible extra arguments
• New AstRendererOptions interface for renderer configuration
• AstRenderer constructor accepts optional third options argument
• 41 new unit tests (140 total across 17 suites)

Full Changelog: v4.0.0...v4.1.0

v4.0.0

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.

• Full TypeScript source with auto-generated type declarations
• Exported types: ASTNode, RenderFunction, RenderRules, MarkdownStyles, MarkdownProps
