WordPress 4.3 has been released! This release introduces menu and site icon controls to the customizer, formatting shortcuts to the editor, stronger password enforcement, and more.
246 volunteers contributed to this release, lead by Konstantin Obenland. At the time of writing this, WordPress 4.3 has been out for a bit over 2 hours and has already been downloaded 373,399 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.
