AMP for WordPress - Version 0.7.0

Version Description

(2018-05-03) =

Render an entire site as "Native AMP" if the theme calls add_theme_support( 'amp' ). See #857, #852, #865, #888. Props westonruter, kaitnyl, ThierryA.
Use the AMP spec to automatically discover the required AMP component scripts to include on the page while post-processing. See #882, #885. Props westonruter.
Automatically concatenate stylesheets from style tags with loaded stylesheets from link tags combined in one style[amp-custom]. See #887, #890, #935. Props westonruter.
Update serialization to use HTML instead of XML; update minimum version of PHP fro, 5.2 to 5.3. See #891.
Add support for widgets. See #870. Props kienstra.
Add support for forms. See #907, #923. Props DavidCramer.
Use "Paired Mode" if the theme calls add_theme_support( 'amp' ) and passes a 'template_dir' value for the AMP templates. See #856, #877. Props westonruter, kaitnyl.
Add AMP implementations of audio/video playlists. See #954. Props kienstra.
Allow full Customization when the theme supports 'amp'. See #952. Props westonruter.
Add support for all default WordPress widgets. See #921, #917. Props kienstra, westonruter.
Add support for more default embeds: Issuu, Post, Meetup, Reddit, Screencast, Tumblr, and WordPress Plugin Directory. See #889. Props kaitnyl.
Allow native WordPress commenting, in fully valid AMP. See #1024, #1029, #871, #909. Props DavidCramer, westonruter.
Add a UI for displaying validation errors, including invalid tags and attributes, with tracing for the source for each error according to which theme/plugin's shortcode, widget, or other hook is responsible. Includes debug mode to suspend sanitizer. See #971, #1012, #1016. Props westonruter, kienstra.
On activating a plugin, validate a front-end page and display a notice if there were errors. See #971. Props westonruter, kienstra.
Creation of AMP-related notifications, on entering invalid content in the 'classic' editor. See #912. Props kienstra, westonruter, ThierryA.
Optionally use <amp-live-list> to display comments, avoiding full-page refreshes on adding comments. And enable making requests for an <amp-live-list>, like for displaying posts. See #1029, #915. Props DavidCramer, westonruter.
Support <amp-bind>, enabling more dynamic elements. See #895. Props westonruter.
Add output buffering, ensuring the entire page is valid AMP. See #929, #857, #931. Props westonruter, ThierryA.
Add validation of host names in URLs. See #983. Props rubengonzalezmrf.
Add WP-CLI scripts to test AMP support of comments and widgets. See #924, #859. Props DavidCramer, kienstra.
Improve test coverage, including for AMP_Theme_Support. See #1034. Props DavidCramer, kienstra.
Update the generated sanitizer file to the AMP spec, and simplify the file that generates it. See #929, #926. Props westonruter.
Several sanitizer updates, including for styles, and preventing valid tags from being removed. See #935, #944, #952. Props westonruter, davisshaver.
Improve sanitization of <amp-img>, <amp-video>, and <amp-iframe>. See #937, #1054. Props kienstra, amedina.
Fix an issue where the JSON inside <script type="application/json"> was wrapped with CDATA. See #891. Props westonruter.
Allow use of AMP components outside of AMP documents, including in PWA. See #1013. Props westonruter.
Access the AMP query var with amp_get_slug(), instead of AMP_QUERY_VAR. See #986. Props westonruter, mjangda.
Update build scripts, including PHP versions in .travis.yml. See #1058, #949. Props westonruter.
Prevent New Relic script from being injected in AMP responses. See #932. Props westonruter.

             == Description ==
-            -
            This plugin adds support for the [Accelerated Mobile Pages](https://www.ampproject.org) (AMP) Project, which is an open source initiative that aims to provide mobile optimized content that can load instantly everywhere.
-            -
            With the plugin active, all posts on your site will have dynamically generated AMP-compatible versions, accessible by appending `/amp/` to the end your post URLs. For example, if your post URL is `http://example.com/2016/01/01/amp-on/`, you can access the AMP version at `http://example.com/2016/01/01/amp-on/amp/`. If you do not have [pretty permalinks](https://codex.wordpress.org/Using_Permalinks#mod_rewrite:_.22Pretty_Permalinks.22) enabled, you can do the same thing by appending `?amp=1`, i.e. `http://example.com/?p=123&amp=1`

            Note #1: homepage, the blog index, and archives are not currently supported.
-            -
            Note #2: this plugin only creates AMP content but does not automatically display it to your users when they visit from a mobile device. That is handled by AMP consumers such as Google Search. For more details, see the [AMP Project FAQ](https://www.ampproject.org/docs/support/faqs.html).

13	== Description ==
14
15	+ Bring the speed and features of the open source [AMP project](https://www.ampproject.org/) to your site, the WordPress way.
16
17	+ With the plugin active, all posts on your site will have AMP-compatible versions, accessible by appending `/amp/` to the end your post URLs. For example, if your post URL is `http://example.com/2016/01/01/amp-on/`, you can access the AMP version at `http://example.com/2016/01/01/amp-on/amp/`.

18
19	+ Also, your pages and custom post types can have AMP versions. Simply check their boxes on the 'AMP Settings' page in `/wp-admin`.
20
21	+ Your entire site can render as "Native AMP" if your theme calls `add_theme_support( 'amp' )`. There will only be one version of each URL: the AMP version. There won't be separate URLs with `/amp` or `?amp` appended. See this [wiki page](https://github.com/Automattic/amp-wp/wiki/Adding-Theme-Support#native-amp) for details and restrictions.
22	+
23	+ Your theme can also use [Paired Mode](https://github.com/Automattic/amp-wp/wiki/Adding-Theme-Support#paired-mode), with your own custom templates for the AMP URLs.
24	+
25	+ "Native AMP" and "Paired Mode" add full support for commenting and widgets.
26	+
27	+ If your theme doesn't support `'amp'`, this will use basic legacy post templates for AMP consumers like Google Search and Twitter. And when visiting the site, the AMP content won't normally appear without appending strings to the URL like `/amp` or `?amp`.
