Version 4.1 of WordPress, named “Dinah” in honor of jazz singer Dinah Washington, is now available for install and upgrade via Softaculous. New features in WordPress 4.1 help you focus on your writing, and the new default theme lets you show it off in style.
The newest default theme, Twenty Fifteen, is a blog-focused theme designed for clarity.
Twenty Fifteen has flawless language support, with help from Google’s Noto font family.
The straightforward typography is readable on any screen size.
Your content always takes center stage, whether viewed on a phone, tablet, laptop, or desktop computer.
Sometimes, you just need to concentrate on putting your thoughts into words. Try turning on distraction-free writing mode. When you start typing, all the distractions will fade away, letting you focus solely on your writing. All your editing tools instantly return when you need them.
Choose a language
Right now, WordPress 4.1 is already translated into over forty languages, with more always in progress. You can switch to any translation on the General Settings screen.
Log out everywhere
If you’ve ever worried you forgot to sign out from a shared computer, you can now go to your profile and log out everywhere.
Vine embeds
