WordPress 4.4 was just released and you can download it from the WordPress.org download page right now. While it has been tested extensively by tens of thousands of people, this is not a security-focused release and you’re encouraged to test it out before you load it on your site.
For a while now you’ve been able to embed various items into WordPress posts (tweets, YouTube videos, etc). Now you can actually embed a full WordPress post into a another WordPress site. This could be very useful if writing a post about another post, and being able to reference the other post in full.
The beginning of the REST API
This is more complicated than can be explained here quickly, but the REST API will allow WordPress to be extended in many awesome ways in the future, and the first part of it as arrived with WordPress 4.4.
While images have been mobile responsive in most WordPress themes for a while now, WordPress 4.4 allows you to insert images that are more responsive and it literally loads different sized images for different users. This decreases your bandwidth and loads your site more quickly, which is a win for everyone.
There is a lot more to talk about with WordPress 4.4, but those are the big changes. Read the full release post on WordPress.org, download it for yourself, and then leave a comment and let us know what you’re most looking forward to with this release.
