AMP Plugin Release v1.0-beta4

Authored by

Today we released 1.0-beta4 release. We are one step closer to releasing the v1.0 version of the AMP plugin.

Newly Redesigned Compatibility Tool

This release includes the newly redesigned Compatibility Tool feature. Care has gone into designing this feature to improve the developer’s experience in converting sites to AMP. It provides better screen designs as well as an improved workflow to help you through the AMP validation process.

Let’s look at some example screenshots to demonstrate this feature:

Redesigned AMP Invalid URLs Page
Redesigned AMP Single URL Errors Page
Redesigned AMP Single Error Term Page

We Need Your Help

We need your help to test this v0.1-beta4 release of the AMP plugin. We ask that you install the plugin, work with the Compatibility Tool, provide feedback on the workflow, and help us to ensure it’s ready for a RC release.

Please download the pre-release build ( Then install and activate in your staging site. You can also checkout the 1.0-beta4-built tag from GitHub.

Previous Beta Releases

Here are the previous beta releases:

This beta version includes all work thus far as we prepare for a release candidate (RC-1) and then the v1.0 stable release.

Not Quite Ready for Production Yet

As usual, we tested this plugin quite a bit, but this software is still in development. We recommend you not (quite) yet ship this to your production site (although we are using it for ourselves in production).

  1. This error index is really useful. Right now, one can only see the errored pages via Google Search Console and solving an error takes 48 hours to update.

    Via this error index page, I believe it will be much easier to see which pages the validator flagged and to fix it.

    Really nice, and useful, work!

    1. Also it is important to note is that errors are listed in WP are caught so that search engine indexers won’t encounter the errors on your site’s AMP pages. Either the plugin will be sanitizing (stripping out) the invalid markup, or it will redirect from the AMP version to the non-AMP version (in paired mode), or it will remove the amp attribute from the HTML element (in native mode).
