Jetpack 3.1 Released!

The new jetpack logo

Automattic has released Jetpack 3.1 with a new logo and a couple of new features. New features include responsive videos, custom post types and an updated admin interface. The update also comes with new API endpoints for the JSON API module, so there’s new functionality for theme and plugin developers. Jetpack just keeps growing and growing, so let’s take a look at some of the features and how to incorporate them into your site. After activation, you should see the following screen:

Custom Post Types (Portfolio)

Jetpack 3.1 comes with the Custom Post Types module. To activate the new feature, just look for the menu:

The new jetpack menu found in the dashboard

Just click on Settings and you should be sent to the Module Activation/Deactivation screen:

The module settings screen

Just make sure that Custom Content Types is activated (blue highlight). You should now be able to see two options. Click on Configure.

You will be brought to the Writing screen, you can find the Custom Content Types options at the bottom. Unfortunately, at this time of this writing, portfolio is the only content type available.

Configure custom post types

After the plugin has been activated, all you need to do is use the following shortcode into your post or page:


You can use the following attributes to customize the display:

  • ‘display_types’: display Project Types. (true/false)
  • ‘display_tags’: display Project Tags. (true/false)
  • ‘display_content’: display project content. (true/false)
  • ‘include_type’: display specific Project Types. Defaults to all. (comma-separated list of Project Type slugs)
  • ‘include_tag’: display specific Project Tags. Defaults to all. (comma-separated list of Project Tag slugs)
  • ‘columns’: number of columns in shortcode. Defaults to 2. (number, 1-6)
  • ‘showposts’: number of projects to display. Defaults to all. (number)

For example:

[portfolio display_type=true display_tags=true columns=4 showposts=8]

This shortcode will display the type, tags, and will show a total of 8 posts in 4 columns.

In the future, the Jetpack team at Automattic promises to keep up with the new standardization of Custom Post Types. You can take a look at the Portfolio Shortcode Documentation to learn more.

Responsive Videos

Responsive videos are extremely simple to add into your theme(s), just add this to your functions.php file:

<?php add_theme_support( 'jetpack-responsive-videos' ); ?>

There is no additional coding needed because everything should work right out of the box.


For theme developers, there some new endpoints that you can use to interact with the JSON API module. You can test them out here.
