 I'm on WordPress 4.7 beta 4, and I'm finding the filter syntax isn't
 working.

 The filter argument is listed in the v2 docs http://v2.wp-
 api.org/reference/posts/. But when I do a GET request to /wp-json/ filter
 is not listed in the args for the /wp/v2/posts GET endpoint.

 I have three posts in my local environment. When I do a GET request to
 /wp-json/wp/v2/posts/?categories=2 I get the one post that belongs to the
 category with the ID 2. This category has the name News and slug news.

 When I do requests like
 /wp-json/wp/v2/posts?filter[cat]=2
 /wp-json/wp/v2/posts?filter[category_name]=News
 /wp-json/wp/v2/posts?filter[posts_per_page]=1
 I get all three of my posts. From what I read on StackOverflow, this
 suggests the API isn't recognising the filter.
