WordPress 4.4 has been released! This release introduces the new default theme Twenty Sixteen, responsive images, post embeds, the basic infrastructure for the upcoming REST API, and more.
466 volunteers contributed to this release, lead by Scott Taylor. That’s a new record for WordPress, almost doubling the last release! At the time of writing this, WordPress 4.4 has been out for only 30 minutes, and has already been downloaded 58,192 times!
All users can now safely update from Dashboard -> Updates or download and update manually, though you should probably backup first just in case, unless you’re already using VaultPress, which you really should be.
If you run into any problems, stop by the known issues first, and please let us know if it’s not covered there!
