WordPress 4.4.1 is now available. This is a security release for all previous versions and we strongly encourage you to update your sites immediately.

WordPress versions 4.4 and earlier are affected by a cross-site scripting vulnerability that could allow a site to be compromised. This was reported by Crtc4L.

There were also several non-security bug fixes:

Emoji support has been updated to include all of the latest emoji characters, including the new diverse emoji! 👍🏿👌🏽👏🏼

Some sites with older versions of OpenSSL installed were unable to communicate with other services provided through some plugins.

If a post URL was ever re-used, the site could redirect to the wrong post.
