WordPress has announced the availability of WordPress 3.5 Beta 1 on September 27, 2012.

In a blog post the said, “this is software still in development and we really don’t recommend that you run it on a production site — set up a test site just to play with the new version.”

To test WordPress 3.5, try the WordPress Beta Tester plugin (you’ll want “bleeding edge nightlies”). Or you can download the beta here (zip).

Here’s some more of what’s new:

  • Appearance: A simplified welcome screen. A new color picker. And the all-HiDPI (retina) dashboard.
  • Accessibility: Keyboard navigation and screen reader support have both been improved.
  • Plugins: You can browse and install plugins you’ve marked as favorites on WordPress.org, directly from your dashboard.
  • Mobile: It’ll be easier to link up your WordPress install with our mobile apps, as XML-RPC is now enabled by default.
  • Links: We’ve hidden the Link Manager for new installs. (Don’t worry, there’s a plugin for that.)
