WordPress 4.1 has been released! This release brings with it a new distraction-free writing mode, the new Twenty Fifteen theme, a new simple language chooser in the general settings, the ability to log out of your account everywhere you may have left it logged in, plugin recommendations based on the plugins you’re already using, and more!
283 volunteers contributed to this release, led by John Blackbourn. At the time of writing this, WordPress 4.1 has been out for less than an hour and has already been downloaded 37,298 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.
