Version 2.0 Beta 2: You Finally Made a Monkey Out of Me

• Load the WP REST API before the main query runs.

  The rest_api_loaded function now hooks into the parse_request action.
  This change prevents the main query from being run on every request and
  allows sites to set WP_USE_THEMES to false. Previously, the main query
  was always being run (SELECT * FROM wp_posts LIMIT 10), even though the
  result was never used and couldn't be cached.

• Register a new field on an existing WordPress object type.

  Introduces register_api_field() to add a field to an object and
  its schema.

• List registered namespaces in the index for feature detection.

  The index (/wp-json by default) now contains a list of the available
  namespaces. This allows for simple feature detection. You can grab the index
  and check namespaces for wp/v3 or pluginname/v2, which indicate the
  supported endpoints on the site.

  (props @rmccue,, #1283)

• Standardize link property relations and support embedding for all resources.

  Change link properties to use IANA-registered relations. Also adds embedding
  support to Attachments, Comments and Terms.
