What’s in WordPress 4.4 “Clifford”

WordPress 4.4 “Clifford” is here. 2015. is year were more important updates have been released for WordPress.

Version 4.4 of WordPress, named “Clifford” in honor of jazz trumpeter Clifford Brown… New features in 4.4 make your site more connected and responsive. Clifford also introduces a new default theme, Twenty Sixteen…

Responsive Images


When users upload images to WordPress, it automatically crops them to smaller sizes. For example, if you upload an image that’s 1500 x 706, the image sizes might look like this:

  • Full Size – 1500 x 706
  • Large – 500 x 235
  • Medium – 300 x 141
  • Thumbnail – 150 x 150

WordPress 4.4 adds srcset and sizes support to WordPress. This allows the software to automatically use and display the right image based on a device’s screen size. If I attach a full size 1500 x 706 image to a post in WordPress 4.4 to be viewed on a desktop, mobile devices will see the large or medium-sized image instead.

This decreases the amount of bandwidth used to load websites since smaller images have smaller file sizes.Responsive images don’t have any settings to configure as the magic happens behind the scenes.

Embed Everything

For a number of years, users have been able to embed content from trusted sources simply by pasting the URL into the visual editor. In 4.4, WordPress itself becomes a trusted oEmbed source which allows anyone to easily embed content from WordPress powered sites.

Embedded content displays in an iframe with a link to comments, a share icon, and an excerpt of the post. Here’s an example of what an oEmbedded post from a site running WordPress 4.4 looks like.

If you want to disable the ability for people to embed your content, install and activate the Disable Embeds plugin. Disable Embeds does the following:

  • Prevents others from embedding your site.
  • Prevents you from embedding other non-whitelisted sites.
  • Disables all JavaScript related to the feature.


As with most WordPress releases, there is now a new default theme–say hello to Twenty Sixteen! Twenty Sixteen is a modern take on the classic blog design. It is completely compatible with all screen sizes and was built to provide  a fluid experience no matter the screen: laptop, smartphone, tablet, you name it.


“Clifford” brings nice features and with rest of few backend changes will help improve old and new themes that are built by the community. All of my clients are already updated with new Clifford and we suggest others to do that as well.

P.S. Don’t forget to backup your database before.
