With this fix release the AMP pages have a template-template_name class added to the html element. e.g. template-amp_thread_view that can be used for specific styling rules on certain pages.
Revert a part of 1.4.7 Beta 2 that allowed other addons to render invalid LD+JSON data in the AMP pages even when the ampEnableJSONLD-option is disabled (which it is by default)
