-* Fixed html export bug.  
+    * Supported `export_on_save` front-matter that exports files when you save your markdown file. However, `phantomjs`, `prince`, `pandoc`, `ebook` are not recommended for `export_on_save` because it's too slow.  
+
+    eg:
+    ```javascript
+    ---
+    export_on_save:
+        html: true
+        markdown: true
+        prince: true
+        phantomjs: true // or "pdf" | "jpeg" | "png" | ["pdf", ...] 
+        pandoc: true
+        ebook: true // or "epub" | "mobi" | "html" | "pdf" | array
+    ---
+    ```        
+    * Added `embed_svg` front-matter option for HTML export, which is enabled by default. 
+* Fixed html export bug.
