v6.6.0

• Dependencies from external domains have been removed
  (with the exception of those that are explicitly defined and optional: Google Analytics, Google Fonts and Disqus).
  Instead, they are now located in the assets folder and managed via Bower.
• KaTeX is no longer loaded on pages that do not contain math blocks.
• preload link tags no longer use onload. Instead callbacks are registered within a script tag.
• Code in code blocks is no longer smaller sized than inline code.
