 * Is it removes from cache only category and tags of one related post or all categories
   and tags on site?
    And what about home?
 * >  modified post and posts index page – clear cache for modified post and posts
   > index page
 * Is this remove only post and parent page of post, not home? – change description“
   posts index page” -> “posts parent page”, because index page – is home…
 * And can you add method “Post, category, home” – to remove only category of post(
   not tags) and home?

 * And one more question:
    What happens with pagination of home or /category/page/
   2/ or /tag/page/2/ when home/category/tag invalidated is page purged or no?

 * Is “Invalidate on comment actions” remove from cache only one commented post 
   or something else?
