Streamdown 2.4: Expanded Customization, Accessibility, and Custom Rendering Features

Streamdown v2.4 introduces customization hooks, accessibility features, and user experience improvements that developers can use when rendering markdown.

Key updates include:

• Customization: The icons prop allows replacing default icons, and createCodePlugin now includes a themes option for Shiki themes, a startLine meta option for specifying the starting line number, and an inlineCode virtual component for inline code.
• Internationalization and Accessibility: The dir prop automatically sets text direction (LTR/RTL), and the translations prop supports custom languages. Table now includes a fullscreen overlay feature via the controls prop.
• Developer Tools: Streaming events can be controlled via onAnimationStart and onAnimationEnd callbacks, and a prefix prop is provided for Tailwind v4 users to prevent class conflicts.

Additionally, a bug where empty lines disappeared in syntax-highlighted blocks and a bug where ordered list animations would restart during streaming have been fixed.
