 <h3>Known issues</h3>
 <ul>  
   <li>Watermark portal images are now saved in the main/default_course_document/images/ folder. If you used portal-wide watermarks before, you might need to upload the watermark image again.</li>
+  <li>A style-specific switch had been added in 1.8.8.2, which improved the appearance of older style but went against MVC's principles and broke copies of Chamilo-based styles. This switch has been removed, which may lead to the breadcrumb in non-chamilo-based styles to appear as less attractive, but keeps the MVC model safe so anyone can modify the appearance safely from the CSS. This might require very little cosmetic changes from you (in your style's default.css file), but we believe it's for the best.</li>
 </ul>
