WordPress v4.4 was recently released and is up on the blog server. It seems to be running fine, but, as always, if you notice any issued, email me.
Along with WordPress core there were a number of plugin and theme updates, as well as a new theme by WordPress called TwentySixteen. More on that in another post.

TinyMCE v4.2.8
