🎉 What's New

✨ Strikethrough Text Formatting

Use ~~text~~ syntax for strikethrough formatting:

@slide {
  title: "Product Updates";
  
  Price: ~~$99~~ **$79** today only!
}

Renders as: Price: ~~$99~~ $79 today only!

🌐 Unicode Escape Sequences

Full support for \uXXXX (4-digit hex) and \xXX (2-digit hex):

@meta {
  title: "Copyright \u00A9 2025";    // ©
  status: "Complete \u2713";         // ✓
  author: "Caf\xE9";                 // Café
}

Features:

Perfect round-trip: parse(serialize(doc)) === doc
Automatic escaping on serialization
Full Unicode range (U+0000 to U+FFFF)

🔍 Position Tracking in Errors

All parser errors now include precise line:column information:

// Before (v1.0)
Error: Missing closing }

// After (v1.1)  
Error: Missing closing } for block meta at 15:42
Error: Expected identifier at 8:5
Error: Invalid number format at 12:18

Benefits: 10x faster debugging for large documents!

🌐 Extended HTML Rendering

HTML output now supports all content block types:

Ordered Lists - Renders as <ol>
Blockquotes - Renders as <blockquote>
Code Blocks - Syntax highlighting with <pre><code>
Images - Proper <img> tags
Links - Proper <a> tags

📝 Enhanced Markdown Export

Markdown export now preserves ALL formatting:

Strikethrough → ~~text~~
Ordered lists → 1. 2. 3.
Blockquotes → > text
Code blocks → ```language ... ```

🔒 Security Improvements

XSS Prevention - All HTML output is properly escaped:

@meta { title: "<script>alert('xss')</script>"; }

// v1.0: Would render dangerous <script> tag
// v1.1: Renders safe: &lt;script&gt;...&lt;/script&gt;

Applies to: All meta properties, document content, slide content, and sheet values.

📝 Example: New Features
