WordPress 4.4 has landed. As usual, early on you will need to manually initiate the auto-update. I’m guessing in a day or so it will just happen by itself.
I did the update on 5 installations and all went through with no dramas. There will no doubt be a slew of updates over the next few days, which is pretty common after a big release. The auto-update feature means you can take the lazy approach and just let it do its thing. 🙂
