+*	Bug fixes:
+	
+	*	Workaround for Internet Explorer bug: 
+		be very sure that `'` is always written as `'`.
+		
+	*	Support for empty images ref: `![image]` and `![image][]`.
+
+	*	Fixed bug in parsing attribute lists definitions.
+
+*	Minor things:
+	
+	*	Now code blocks are written as a `<code>` element inside a `<pre>`, and
+		`<code>` elements have both `class` and `lang` attributes set 
+		to the specified language.
+		
+		Example:
+
+			    Example
+			{:lang=ruby}
+		{:lang=markdown}
+		
+		produces:
+		
+			<pre><code class='ruby' lang='ruby'>Example</code></pre>
+		{:lang=xml}

 *	Syntax changes:
 
 	*	Compatibility with newest Markdown.pl: `[text]` as a synonim of `[text][]`.
