Access your site's data through an easy-to-use HTTP REST API. (Version 2)

== Description ==
WordPress is moving towards becoming a fully-fledged application framework, and we need new APIs. This project was born to create an easy-to-use, easy-to-understand and well-tested framework for creating these APIs, plus creating APIs for core.

This plugin provides an easy to use REST API, available via HTTP. Grab your site's data in simple JSON format, including users, posts, taxonomies and more. Retrieving or updating data is as simple as sending a HTTP request.

Want to get your site's posts? Simply send a `GET` request to `/wp-json/wp/v2/posts`. Update user with ID 4? Send a `PUT` request to `/wp-json/wp/v2/users/4`. Get all posts with the search term "awesome"? `GET /wp-json/wp/v2/posts?filter[s]=awesome`. It's that easy.

The WordPress REST API exposes a simple yet easy interface to WP Query, the posts API, post meta API, users API, revisions API and many more. Chances are, if you can do it with WordPress, the API will let you do it.

The REST API also includes an easy-to-use JavaScript API based on Backbone models, allowing plugin and theme developers to get up and running without needing to know anything about the details of getting connected.

Check out [our documentation][docs] for information on what's available in the API and how to use it. We've also got documentation on extending the API with extra data for plugin and theme developers!

All tickets for the project are being tracked on [GitHub][]. You can also take a look at the [recent updates][] for the project.

[docs]: http://v2.wp-api.org/
[GitHub]: https://github.com/WP-API/WP-API
[recent updates]: http://make.wp-api.org/

== Installation ==

Install the WP REST API via the plugin directory, or by uploading the files manually to your server.

For full-flavoured API support, you'll need to be using pretty permalinks to use the plugin, as it uses custom rewrite rules to power the API.

Once you've installed and activated the plugin, [check out the documentation](http://v2.wp-api.org/) for details on your newly available endpoints.

== Changelog ==

= 2.0 Beta 13.0 (March 29, 2016) =

* BREAKING CHANGE: Fix Content-Disposition header parsing.

  Allows regular form submissions from HTML forms, as well as properly formatted HTTP requests from clients. Note: this breaks backwards compatibility, as previously, the header parsing was completely wrong.

  (props @rmccue, [#2239](https://github.com/WP-API/WP-API/pull/2239))

* BREAKING CHANGE: Use compact links for embedded responses if they are available.

  Introduces curies for sites running WordPress 4.5 or greater; no changes for those running WordPress 4.4.

  (props @joehoyle, [#2412](https://github.com/WP-API/WP-API/pull/2412))

* JavaScript client updates:

  * Support lodash, plus older and newer underscore: add an alias for `_.contains`
  * Add args and options on the model/collection prototypes
  * Rework category/tag mixins to support new API structure
  * Add workaround for the null/empty values returned by the API when creating a new post * these values are not accepted for subsequent updates/saves, so explicitly excluding them. See https://github.com/WP-API/WP-API/pull/2393
  * Better handling of the (special) `me` endpoint
  * Schema parsing cleanup
  * Introduce `wp.api.loadPromise` so developers can ensure api load complete before using

  (props @kjbenk, [#2377](https://github.com/WP-API/WP-API/pull/2377))

* Supports taxonomy collection args on posts endpoint.

  (props @joehoyle, [#2287](https://github.com/WP-API/WP-API/pull/2287))

* Removes post meta link from post response.

  (props @joehoyle, [#2288](https://github.com/WP-API/WP-API/pull/2288))

* Registers `description` attribute when registering args from schema.

  (props @danielbachhuber, [#2362](https://github.com/WP-API/WP-API/pull/2362))

* Uses `$comment` from the database with `rest_insert_comment` action.

  (props @danielbachhuber, [#2349](https://github.com/WP-API/WP-API/pull/2349))

* Removes unnecessary global variables from users controller.

  (props @claudiosmweb, [#2335](https://github.com/WP-API/WP-API/pull/2335))

* Ensures `GET /wp/v2/categories` with out of bounds offset doesn't return results.

  (props @danielbachhuber, [#2313](https://github.com/WP-API/WP-API/pull/2313))

* Adds top-level support for date queries on posts and comments.

  (props @BE-Webdesign, [#2266](https://github.com/WP-API/WP-API/pull/2266), [#2291](https://github.com/WP-API/WP-API/pull/2291))

* Respects `show_avatars` setting for comments.

  (props @BE-Webdesign, [#2271](https://github.com/WP-API/WP-API/pull/2271))

* Uses cached `get_the_terms()` for terms-for-post for better performance.

  (props @rmccue, [#2257](https://github.com/WP-API/WP-API/pull/2257))

* Ensures comments search is an empty string.

  (props @rmccue, [#2256](https://github.com/WP-API/WP-API/pull/2256))

* If no title is provided in create attachment request or file metadata, falls back to filename.

  (props @danielbachhuber, [#2254](https://github.com/WP-API/WP-API/pull/2254))

* Removes unused `$img_url_basename` variable in attachments controller.

  (props @danielbachhuber, [#2250](https://github.com/WP-API/WP-API/pull/2250))

= 2.0 Beta 12.0 (February 9, 2016) =

* BREAKING CHANGE: Removes meta endpoints from primary plugin.

  If your project depends on post meta endpoints, please install [WP REST API Meta Endpoints](https://wordpress.org/plugins/rest-api-meta-endpoints/). For the gory history of meta, read [#1425](https://github.com/WP-API/WP-API/issues/1425) and linked issues. At this time, we recommend using `register_rest_field()` to expose meta ([docs](http://v2.wp-api.org/extending/modifying/)).

  (props @danielbachhuber, [#2172](https://github.com/WP-API/WP-API/pull/2172))

* BREAKING CHANGE: Returns original resource when deleting PTCU.

  Now that all resources require the `force` param, we don't need to wrap delete responses with the `trash` state.

  (props @danielbachhuber, [#2163](https://github.com/WP-API/WP-API/pull/2163))

* BREAKING CHANGE: Uses `roles` rather than `role` in the Users controller.

  Building the REST API gives us the opportunity to standardize on `roles`, instead of having both `roles` and `role`.

  (props @joehoyle, [#2177](https://github.com/WP-API/WP-API/pull/2177))

* BREAKING CHANGES: Moves to consistent use of `context` throughout controllers.

  Contexts limit the data present in the response. Here's how to think of them: `embed` correlates with sidebar representation, `view` represents the primary public view, and `edit` is the data expected for an editor.

  (props @danielbachhuber, [#2205](https://github.com/WP-API/WP-API/pull/2205), [#2204](https://github.com/WP-API/WP-API/pull/2204), [#2203](https://github.com/WP-API/WP-API/pull/2203), [#2218](https://github.com/WP-API/WP-API/pull/2218), [#2216](https://github.com/WP-API/WP-API/pull/2216), [#2230](https://github.com/WP-API/WP-API/pull/2230), [#2184](https://github.com/WP-API/WP-API/pull/2184), [#2235](https://github.com/WP-API/WP-API/pull/2235))

* BREAKING CHANGE: Removes `post_*` query param support for `GET /wp/v2/comments`.

  The proper pattern is to use `GET /wp/v2/posts` to fetch the post IDs to limit the request to.

  (props @danielbachhuber, [#2165](https://github.com/WP-API/WP-API/pull/2165))

* BREAKING CHANGE: Introduces `rest_validate_request_arg()`/`rest_sanitize_request_arg()`.

  Dedicated functions means we can use them for validating / sanitizing query args too. Removes `WP_REST_Controller::validate_schema_property()` and `WP_REST_Controller::sanitize_schema_property()`.

  (props @danielbachhuber, [#2166](https://github.com/WP-API/WP-API/pull/2166), [#2213](https://github.com/WP-API/WP-API/pull/2213))

* Requires minimum value of 1 for `page` param.

  (props @danielbachhuber, [#2241](https://github.com/WP-API/WP-API/pull/2241))

* Introduces `media_type` and `mime_type` params for `GET /wp/v2/media`.

  (props @danielbachhuber, [#2231](https://github.com/WP-API/WP-API/pull/2231))

* Uses the term cache for post data.

  (props @rmccue, [#2234](https://github.com/WP-API/WP-API/pull/2234))

* Supports for querying comments where `post=0`.

  (props @danielbachhuber, [#1865](https://github.com/WP-API/WP-API/pull/1865))

* Exposes taxonomy and post type capabilities in `context=edit`.

  (props @danielbachhuber, [#2216](https://github.com/WP-API/WP-API/pull/2216))

* Errors early when user can't GET types or taxonomies when `context=edit`.

  (props @danielbachhuber, [#2218](https://github.com/WP-API/WP-API/pull/2218))

* Passes original $request context to `prepare_items_query`.

  (props @danielbachhuber, [#2211](https://github.com/WP-API/WP-API/pull/2211))

* Adds `parent` and `parent_exclude` params to GET Comments.

  (props @danielbachhuber, [#2206](https://github.com/WP-API/WP-API/pull/2206))

* Enforces minimum 1 and maximum 100 values for `per_page` parameter.

  (props @danielbachhuber, [#2209](https://github.com/WP-API/WP-API/pull/2209))

* Adds `author` and `author_exclude` params to GET Posts and Comments.

  (props @danielbachhuber, [#2200](https://github.com/WP-API/WP-API/pull/2202), [#2200](https://github.com/WP-API/WP-API/pull/2202))

* Adds `menu_order` param for `GET` Pages; support `menu_order` orderby.

  (props @danielbachhuber, [#2193](https://github.com/WP-API/WP-API/pull/2193))

* Only calls `sanitize_text_field()` when sanitizing `type=string,format=email`.

  (props @danielbachhuber, [#2185](https://github.com/WP-API/WP-API/pull/2185))

* Validates `GET /wp/v2/comments` private query params.

  Returns an error when user doesn't have permission to use them, instead of silently discarding.

  (props @danielbachhuber, [#2178](https://github.com/WP-API/WP-API/pull/2178))

* Explicitly prevents uploading attachments to other attachments or revisions.

  (props @danielbachhuber, [#2180](https://github.com/WP-API/WP-API/pull/2180))

* Permits user urls to be edited through the API.

  (props @danielbachhuber, [#2182](https://github.com/WP-API/WP-API/pull/2182))

* Marks all Status, Type and Taxonomy fields as `readonly`.

  (props @danielbachhuber, [#2181](https://github.com/WP-API/WP-API/pull/2181))

* Adds validation callbacks to collection query params.

  (props @danielbachhuber, [#2170](https://github.com/WP-API/WP-API/pull/2170), [#2171](https://github.com/WP-API/WP-API/pull/2171), [#2176](https://github.com/WP-API/WP-API/pull/2176), [#2174](https://github.com/WP-API/WP-API/pull/2174), [#2175](https://github.com/WP-API/WP-API/pull/2175))

* Links taxonomy terms to the post type collections they support.

  (props @danielbachhuber, [#2167](https://github.com/WP-API/WP-API/pull/2167))

* Returns error when making a `GET` request with invalid context.

  (props @danielbachhuber, [#2169](https://github.com/WP-API/WP-API/pull/2169))

* Adds `trash` status to `GET /wp/v2/statuses`.

  (props @danielbachhuber, [#2158](https://github.com/WP-API/WP-API/pull/2158))

* Indicates when fields have HTML in schema.

  (props @joehoyle, [#2159](https://github.com/WP-API/WP-API/pull/2159))

* Permits viewing of User who has published any Public posts.

  (props @danielbachhuber, [#2155](https://github.com/WP-API/WP-API/pull/2155))

* Respects `show_avatars` option when adding avatars to Users.

  (props @nullvariable, [#2151](https://github.com/WP-API/WP-API/pull/2151))

* Controllers use `$namespace` and `$rest_base` class variables for easier subclassing.

  (props @danielbachhuber, [#2119](https://github.com/WP-API/WP-API/pull/2119), [#2130](https://github.com/WP-API/WP-API/pull/2130), [#2131](https://github.com/WP-API/WP-API/pull/2131), [#2132](https://github.com/WP-API/WP-API/pull/2132), [#2133](https://github.com/WP-API/WP-API/pull/2133), [#2134](https://github.com/WP-API/WP-API/pull/2134), [#2139](https://github.com/WP-API/WP-API/pull/2139), [#2141](https://github.com/WP-API/WP-API/pull/2141), [#2142](https://github.com/WP-API/WP-API/pull/2142))

= 2.0 Beta 11.0 (January 25, 2016) =

* BREAKING CHANGE: Moves Post->Term relations to the Post Resource

  Previously, a client would fetch a Post's Tags with `GET /wp/v2/posts/<id>/tags`.

  In Beta 11, an array of term ids is included on the Post resource.

  The collection of terms for a Post can be fetched with `GET /wp/v2/tags?post=<id>`.

  The `WP_REST_Posts_Terms_Controller` class no longer exists.

  (props @joehoyle, [#2063](https://github.com/WP-API/WP-API/pull/2063))

* BREAKING CHANGE: Adds latest JS client including a minified version.

  See pull request for a summarized changelog.

  (props @adamsilverstein, [#1981](https://github.com/WP-API/WP-API/pull/1981))

* BREAKING CHANGE: Changes `featured_image` attribute on Posts to `featured_media`.

  While featuring other attachment types isn't yet officially supported, this makes it easier for us to introduce the possibility in the future.

  (props @danielbachhuber, [#2044](https://github.com/WP-API/WP-API/pull/2044))

* BREAKING CHANGE: Uses discrete schema title for categories and tags.

  If you've used `register_rest_field( 'term' )`, you'll need to change `'term'` to `'tag'` and/or `'category'`.

  (props @danielbachhuber, [#2005](https://github.com/WP-API/WP-API/pull/2005))

* BREAKING CHANGE: Makes many filters dynamic based on the controller type.

  If you were using the `rest_prepare_term` filter, you'll need to change it to `rest_prepare_post_tag` or `rest_prepare_category`.

  If you were using `rest_post_query` or `rest_terms_query`, you'll need update your use to `rest_page_query`, etc.

  If you were using `rest_post_trashable`, `rest_insert_post` or `rest_delete_post`, they are now dynamic based on the post type slug.

  (props @danielbachhuber, [#2008](https://github.com/WP-API/WP-API/pull/2008), [#2010](https://github.com/WP-API/WP-API/pull/2010), [#2057](https://github.com/WP-API/WP-API/pull/2057), [#2058](https://github.com/WP-API/WP-API/pull/2058))

* Renames `GET /wp/v2/comments` `user` param to `author` to match resource attribute.

  Not a breaking change, because it didn't work in the first place.

  (props @danielbachhuber, [#2105](https://github.com/WP-API/WP-API/pull/2105))

* Adds support for `GET /wp/v2/pages parent=1,2,3`.

  (props @danielbachhuber, [#2101](https://github.com/WP-API/WP-API/pull/2101))

* Persists image metadata title and caption when not present in the request.

  (props @danielbachhuber, [#2079](https://github.com/WP-API/WP-API/pull/2079))

* Add `parent_exclude` param to `GET /wp/v2/posts`.

  (props @danielbachhuber, [#2077](https://github.com/WP-API/WP-API/pull/2077))

* Adds `slug` param support for collections of Posts, Users, and Taxonomy Terms.

  (props @danielbachhuber, [#2071](https://github.com/WP-API/WP-API/pull/2071), [#2072](https://github.com/WP-API/WP-API/pull/2072), [#2103](https://github.com/WP-API/WP-API/pull/2103))

* When a comment is already trashed, returns `410:rest_already_trashed`.

  (props @danielbachhuber, [#2069](https://github.com/WP-API/WP-API/pull/2069))

* Filter the responses by context after processing additional fields.

  (props @danielbachhuber, [#2067](https://github.com/WP-API/WP-API/pull/2067))

* Adds `offset` param support for collections of Posts, Users, Comments, and Taxonomy Terms.

  (props @danielbachhuber, [#2061](https://github.com/WP-API/WP-API/pull/2061), [#2062](https://github.com/WP-API/WP-API/pull/2062), [#2064](https://github.com/WP-API/WP-API/pull/2064), [#2076](https://github.com/WP-API/WP-API/pull/2076))

* Adds `rest_insert_{$taxonomy}` and `rest_delete_{$taxonomy}` actions.

  (props @danielbachhuber, [#2060](https://github.com/WP-API/WP-API/pull/2060))

* Provides more helpful error message/code on Post Create/Update fail.

  (props @danielbachhuber, [#2053](https://github.com/WP-API/WP-API/pull/2053))

* Forces `GET /wp/v2/media` to be limited to `'status' => [ inherit, private, trash ]`

  (props @danielbachhuber, [#2026](https://github.com/WP-API/WP-API/pull/2026))

* Uses more correct error code for `Comment::delete` permission check.

  (props @danielbachhuber, [#2054](https://github.com/WP-API/WP-API/pull/2054))

* Calls `prepare_item_for_response()` directly in create and update methods.

  This lets us pass the original request through, giving the method and its filter genuine context, and avoids an
unnecessary call to `get_item()`.

  (props @danielbachhuber, [#2038](https://github.com/WP-API/WP-API/pull/2038), [#2040](https://github.com/WP-API/WP-API/pull/2040), [#2041](https://github.com/WP-API/WP-API/pull/2041), [#2043](https://github.com/WP-API/WP-API/pull/2043), [#2042](https://github.com/WP-API/WP-API/pull/2042))

* Moves permission check methods across controllers.

  Placing them above the method they're supposed to check makes the code more readable.

  (props @danielbachhuber, [#2030](https://github.com/WP-API/WP-API/pull/2030), [#2029](https://github.com/WP-API/WP-API/pull/2029), [#2034](https://github.com/WP-API/WP-API/pull/2034), [#2036](https://github.com/WP-API/WP-API/pull/2036), [#2037](https://github.com/WP-API/WP-API/pull/2037), [#2035](https://github.com/WP-API/WP-API/pull/2035), [#2039](https://github.com/WP-API/WP-API/pull/2039))

* Requires `force` argument for `DELETE /wp/v2/<taxonomy>/<id>`.

  (props @danielbachhuber, [#2028](https://github.com/WP-API/WP-API/pull/2028))

* Conditionally requires and defines REST API classes and functions.

  (props @danielbachhuber, [#2023](https://github.com/WP-API/WP-API/pull/2023), [#2024](https://github.com/WP-API/WP-API/pull/2024))

* Avoid a duplicate query for the comment count.

  (props @rmccue, [#2015](https://github.com/WP-API/WP-API/pull/2015))

* Parses `$date` if available in `prepare_date_response()`

  (props @adamsilverstein, [#1951](https://github.com/WP-API/WP-API/pull/1951))

* Abstracts `POST /wp/v2/media` permissions check.

  (props @danielbachhuber, [#2003](https://github.com/WP-API/WP-API/pull/2003))

* Adds `exclude` param to getting collections of Posts, Users, Comments, and Taxonomy Terms.

  (props @danielbachhuber, [#1998](https://github.com/WP-API/WP-API/pull/1998), [#1999](https://github.com/WP-API/WP-API/pull/1999), [#2000](https://github.com/WP-API/WP-API/pull/2000), [#2002](https://github.com/WP-API/WP-API/pull/2002))

* Adds `rest_comment_query` for filtering `GET /wp/v2/comments`.

  (props @danielbachhuber, [#2007](https://github.com/WP-API/WP-API/pull/2007))

* Uses HTTP status code `500` for `db_update_error` when creating an attachment.

  (props @danielbachhuber, [#1993](https://github.com/WP-API/WP-API/pull/1993))

* Adds helpful description to `force` param across all `DELETE` registrations

  (props @danielbachhuber, [#2004](https://github.com/WP-API/WP-API/pull/2004), [#2027](https://github.com/WP-API/WP-API/pull/2027))

* In `GET /wp/v2/<taxonomy>`, drops support for `orderby=>term_id`.

  Only one `id` is exposed through the REST API.

  (props @danielbachhuber, [#1990](https://github.com/WP-API/WP-API/pull/1990))

= 2.0 Beta 10.0 (January 11, 2016) =

* SECURITY: Ensure media of private posts are private too.

  Reported by @danielbachhuber on 2016-01-08.

* BREAKING CHANGE: Removes compatibility repo for WordPress 4.3.

  WordPress 4.4 is now the minimum supported WordPress version.

  (props @danielbachhuber, [#1848](https://github.com/WP-API/WP-API/pull/1848))

* BREAKING CHANGE: Changes link relation for types and taxonomies.

  In Beta 9, this link relation was introduced as `item`, which isn't correct. The relation has been changed to `https://api.w.org/items`.

  (props @danielbachhuber, [#1853](https://github.com/WP-API/WP-API/pull/1853))

* BREAKING CHANGE: Introduces `edit` context for `wp/v2/types` and `wp/v2/taxonomies`.

  Some fields have moved into this context, which require `edit_posts` and `manage_terms`, respectively.

  (props @danielbachhuber, [#1894](https://github.com/WP-API/WP-API/pull/1894), [#1864](https://github.com/WP-API/WP-API/pull/1864))

* BREAKING CHANGE: Removes `post_format` as a term `_link` for Posts.

  Post formats aren't a custom taxonomy in the eyes of the REST API.

  (props @danielbachhuber, [#1854](https://github.com/WP-API/WP-API/pull/1854))

* Declares `parent` query param for Pages.

  (props @danielbachhuber, [#1975](https://github.com/WP-API/WP-API/pull/1975))

* Permits logged-in users to query for media.

  (props @danielbachhuber, [#1973](https://github.com/WP-API/WP-API/pull/1973))

* Removes duplicated query params from Terms controller.

  (props @danielbachhuber, [#1963](https://github.com/WP-API/WP-API/pull/1963))

* Adds `include` param to `/wp/v2/posts`, `/wp/v2/users`, `/wp/v2/<taxonomy>` and `/wp/v2/comments`.

  (props @danielbachhuber, [#1961](https://github.com/WP-API/WP-API/pull/1961), [#1964](https://github.com/WP-API/WP-API/pull/1964), [#1968](https://github.com/WP-API/WP-API/pull/1968), [#1971](https://github.com/WP-API/WP-API/pull/1971))

* Ensures `GET /wp/v2/posts` respects `order` and `orderby` params.

  (props @danielbachhuber, [#1962](https://github.com/WP-API/WP-API/pull/1962))

* Fixes fatal by loading `wp-admin/includes/user.php` to expose `wp_delete_user()`.

  (props @danielbachhuber, [#1958](https://github.com/WP-API/WP-API/pull/1958))

* Permits making a post sticky when also supplying an empty password.

* BREAKING CHANGE: Move tags and categories to top-level endpoints.

  Tags are now accessible at `/wp/v2/tags`, and categories accessible at `/wp/v2/categories`. Post terms reside at `/wp/v2/posts/<id>/tags` and `/wp/v2/<id>/categories`.

  (props @danielbachhuber, [#1802](https://github.com/WP-API/WP-API/pull/1802))

  This is consistent with `/wp/v2/types` and `/wp/v2/statuses`.

  (props @danielbachhuber, [#1825](https://github.com/WP-API/WP-API/pull/1825))

* BREAKING CHANGE: Remove `rest_get_timezone()`.

  `json_get_timezone()` was only ever used in v1. This function causes fatals, and shouldn't be used.

  (props @danielbachhuber, [#1823](https://github.com/WP-API/WP-API/pull/1823))

* BREAKING CHANGE: Rename `register_api_field()` to `register_rest_field()`.

  Introduces a `register_api_field()` function for backwards compat, which calls `_doing_it_wrong()`. However, `register_api_field()` won't ever be committed to WordPress core, so you should update your function calls.

  (props @danielbachhuber, [#1824](https://github.com/WP-API/WP-API/pull/1824))

* BREAKING CHANGE: Change taxonomies' `post_type` argument to `type`.

  For a long time, the REST API loaded wp-admin/includes/admin.php to make use of specific admin utilities. Now, it only loads those admin utilities when it needs them.

* Show public user information through the user controller.

  In WordPress as of [r32683](https://core.trac.wordpress.org/changeset/32683) (scheduled for 4.3), `WP_User_Query` now has support for getting users with published posts.

  To match current behaviour in WordPress themes and feeds, we now expose this public user information. This includes the avatar, description, user ID, custom URL, display name, and URL, for users who have published at least one post on the site. This information is available to all clients; other fields and data for all users are still only available when authenticated.

  (props @joehoyle, @rmccue, @Shelob9, [#1397][gh-1397], [#839][gh-839], [#1435][gh-1435])

* Send schema in OPTIONS requests and index.

  Rather than using separate `/schema` endpoints, the schema for items is now available through an OPTIONS request to the route. This means that full documentation is now available for endpoints through an OPTIONS request; this includes available methods, what data you can pass to the endpoint, and the data you'll get back.

  This data is now also available in the main index and namespace indexes. Simply request the index with `context=help` to get full schema data. Warning: this response will be huge. The schema for single endpoints is also available in the collection's OPTIONS response.

  **⚠️ This breaks backwards compatibility** for clients relying on schemas being at their own routes. These clients should instead send `OPTIONS` requests.

  Custom endpoints can register their own schema via the `schema` option on the route. This option should live side-by-side with the endpoints (similar to `relation` in WP's meta queries), so your registration call will look something like:

  ```php
  register_rest_route( 'test-ns', '/test', array(
    array(
      'methods' => 'GET',
      'callback' => 'my_test_callback',
    ),

    'schema' => 'my_schema_callback',
  ) );
  ```

  (props @rmccue, [#1415][gh-1415], [#1222][gh-1222], [#1305][gh-1305])

* Update JavaScript API for version 2.

  Our fantastic JavaScript API from version 1 is now available for version 2, refreshed with the latest and greatest changes.

  As a refresher: if you want to use it, simply make your script depend on `wp-api` when you enqueue it. If you want to enqueue the script manually, add `wp_enqueue_script( 'wp-api' )` to a callback on `wp_enqueue_scripts`.

  (props @tlovett1, @kadamwhite, @nathanrice, [#1374][gh-1374], [#1320][gh-1320])

* Embed links inside items in a collection.

  Previously when fetching a collection of items, you only received the items themselves. To fetch the links as well via embedding, you needed to make a request to the single item with `_embed` set.

  No longer! You can now request a collection with embeds enabled (try `/wp/v2/posts?_embed`). This will embed links inside each item, allowing you to build interface items much easier (for example, post archive pages can get featured image data at the same time).

  This also applies to custom endpoints. Any endpoint that returns a list of objects will automatically have the embedding applied to objects inside the list.

  (props @rmccue, [#1459][gh-1459], [#865][gh-865])

* Fix potential XSS vulnerability.

  Requests from other origins could potentially run code on the API domain, allowing cross-origin access to authentication cookies or similar.

  Reported by @xknown on 2015-07-23.

* Move `/posts` `WP_Query` vars back to `filter` param.

  In version 1, we had internal `WP_Query` vars available via `filter` (e.g. `filter[s]=search+term`). For our first betas of version 2, we tried something different and exposed these directly on the endpoint. The experiment has now concluded; we didn't like this that much, so `filter` is back.

  We plan on adding nicer looking arguments to collections in future releases, with a view towards being consistent across different collections. We also plan on opening up the underlying query vars via `filter` for users, comments, and terms as well.

  **⚠️ This breaks backwards compatibility** for users using WP Query vars. Simply change your `x=y` parameter to `filter[x]=y`.

  (props @WP-API, [#1420][gh-1420])

* Respect `rest_base` for taxonomies.

  **⚠️ This breaks backwards compatibility** by changing the `/wp/v2/posts/{id}/terms/post_tag` endpoint to `/wp/v2/posts/{id}/tag`.

  (props @joehoyle, [#1466][gh-1466])

* Add permission check for retrieving the posts collection in edit context.

  By extension of the fact that getting any individual post yields a forbidden context error when the `context=edit` and the user is not authorized, the user should also not be permitted to list any post items when unauthorized.

  (props @danielpunkass, [#1412][gh-1412])

* Ensure the REST API URL always has a trailing slash.

  Previously, when pretty permalinks were enabled, the API URL during autodiscovery looked like `/wp-json`, whereas the non-pretty permalink URL looked like `?rest_route=/`. These are now consistent, and always end with a slash character to simplify client URL building.

  (props @danielpunkass, @rmccue, [#1426][gh-1426], [#1442][gh-1442], [#1455][gh-1455], [#1467][gh-1467])

* Use `wp_json_encode` instead of `json_encode`

  Since WordPress 4.1, `wp_json_encode` has been available to ensure encoded values are sane, and that non-UTF8 encodings are supported. We now use this function rather than doing the encode ourselves.

  (props @rmccue, @pento, [#1417][gh-1417])

* Add `role` to schema for users.

  The available roles you can assign to a user are now available in the schema as an `enum`.

  (props @joehoyle, [#1400][gh-1400])

* Use the schema for validation inside the comments controller.

  Previously, the schema was merely a decorative element for documentation inside the comments controller. To bring it inline with our other controllers, the schema is now used internally for validation.

  (props @joehoyle, [#1422][gh-1422])

* Don't set the Location header in update responses.

  Previously, the Location header was sent when updating resources due to some inadvertent copypasta. This header should only be sent when creating to direct clients to the new resource, and isn't required when you're already on the correct resource.

  (props @rachelbaker, [#1441][gh-1441])

* Re-enable the `rest_insert_post` action hook for `WP_REST_Posts_Controller`

  This was disabled during 2.0 development to avoid breaking lots of plugins on the `json_insert_post` action. Now that we've changed namespaces and are Mostly Stable (tm), we can re-enable the action.

  (props @jaredcobb, [#1427][gh-1427], [#1424][gh-1424])

* Fix post taxonomy terms link URLs.

  When moving the routes in a previous beta, we forgot to correct the links on post objects to the new correct route. Sorry!

  (props @rachelbaker, @joehoyle, [#1447][gh-1447], [#1383][gh-1383])

* Use `wp_get_attachment_image_src()` on the image sizes in attachments.

  Since the first versions of the API, we've been building attachment URLs via `str_replace`. Who knows why we were doing this, but it caused problems with custom attachment URLs (such as CDN-hosted images). This now correctly uses the internal functions and filters.

  (props @joehoyle, [#1462][gh-1462])

* Make the embed context a default, not forced.

  If you want embeds to bring in full data rather than with `context=edit`, you can now change the link to specify `context=view` explicitly.

  (props @rmccue, [#1464][gh-1464])

* Ensure we always use the `term_taxonomy_id` and never expose `term_id` publicly.

  Previously, `term_id` was inadvertently exposed in some error responses.

  (props @jdolan, [#1430][gh-1430])

* Fix adding alt text to attachments on creation.

  Previously, this could only be set when updating an attachment, not when creating one.

  (props @joehoyle, [#1398][gh-1398])

* Throw an error when registering routes without a namespace.

  Namespaces should **always** be provided when registering routes. We now throw a `doing_it_wrong` error when attempting to register one. (Previously, this caused a warning, or an invalid internal route.)

  If you *really* need to register namespaceless routes (e.g. to replicate an existing API), call `WP_REST_Server::register_route` directly rather than using the convenience function.

  (props @joehoyle, @rmccue, [#1355][gh-1355])

* Show links on embeds.

  Previously, links were accidentally stripped from embedded response data.

  (props @rmccue, [#1472][gh-1472])

* Clarify insufficient permisssion error when editing posts.

  (props @danielpunkass, [#1411][gh-1411])

* Improve @return inline docs for rest_ensure_response()

  (props @Shelob9, [#1328][gh-1328])

* Check taxonomies exist before trying to set properties.

  (props @joehoyle, @rachelbaker, [#1354][gh-1354])

* Update controllers to ensure we use `sanitize_callback` wherever possible.

  (props @joehoyle, [#1399][gh-1399])

* Add more phpDoc documentation, and correct existing documentation.

  (props @Shelob9, @rmccue, [#1432][gh-1432], [#1433][gh-1433], [#1465][gh-1465])

* Update testing infrastructure.

  Travis now runs our coding standards tests in parallel, and now uses the new, faster container-based testing infrastructure.

= 2.0 Beta 3.0 (July 1, 2015) =

= 2.0 Beta 2.0 (May 28, 2015) =

* 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.

  (props @rmccue, [#1270][gh-1270])

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

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

  (props @joehoyle, @rachelbaker, [#927][gh-927])
  (props @joehoyle, [#1207][gh-1207])
  (props @joehoyle, [#1243][gh-1243])

* Add endpoints for viewing, creating, updating, and deleting Terms for a Post.

  The new `WP_REST_Posts_Terms_Controller` class controller supports routes for
  Terms that belong to a Post.

  (props @joehoyle, @danielbachhuber, [#1216][gh-1216])

* Add pagination headers for collection queries.

  The `X-WP-Total` and `X-WP-TotalPages` are now present in terms, comments,
  and users collection responses.

  (props @danielbachhuber, [#1182][gh-1182])
  (props @danielbachhuber, [#1191][gh-1191])
  (props @danielbachhuber, @joehoyle, [#1197][gh-1197])

* 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][gh-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.

* Add support for Composer dependency management.

  Allows you to recursively install/update the WP REST API inside of WordPress
  plugins or themes.

  (props @QWp6t, [#1157][gh-1157])

* Return full objects in the delete response.

  Instead of returning a random message when deleting a Post, Comment, Term, or
  User provide the original resource data.

  (props @danielbachhuber, [#1253][gh-1253])
  (props @danielbachhuber, [#1254][gh-1254])
  (props @danielbachhuber, [#1255][gh-1255])

  required parameters.

* Declare supported arguments for Comment and User collection queries.

  (props @danielbachhuber, [#1211][gh-1211])
  (props @danielbachhuber, [#1217][gh-1217])

* Automatically validate parameters based on Schema data.

  (props @joehoyle, [#1128][gh-1128])

* Use the `show_in_rest` attributes for exposing Taxonomies.

  (props @joehoyle, [#1279][gh-1279])

* Handle `parent` when creating or updating a Term.

  (props @joehoyle, [#1221][gh-1221])

* Limit fields returned in `embed` context User responses.

  (props @rachelbaker, [#1251][gh-1251])

* Only include `parent` in term response when tax is hierarchical.

  (props @danielbachhuber, [#1189][gh-1189])

* Fix bug in creating comments if `type` was not set.

* Only link `author` when there's a valid author

  (props @danielbachhuber, [#1203][gh-1203])

* Only permit querying by parent term when tax is hierarchical.

  (props @danielbachhuber, [#1219][gh-1219])

* Only permit deleting posts of the proper type

  (props @danielbachhuber, [#1257][gh-1257])

* Set pagination headers even when no found posts.

  (props @danielbachhuber, [#1209][gh-1209])

* Correct prefix in `rest_request_parameter_order` filter.

  (props @quasel, [#1158][gh-1158])

* Retool `WP_REST_Terms_Controller` to follow Posts controller pattern.

  (props @danielbachhuber, [#1170][gh-1170])
