Tumblr is now testing “Pages”:

You can now add static pages to your blog, with a few very useful options. Head to your blog’s Customize page and click the “Pages” menu to get started. There are currently three types of Pages you can create:

• Standard Layout. Create a simple page with a title and body using your current theme.
• Custom Layout. Create a page with a completely separate layout.
• Redirect. Forward a route to a page on another domain. Useful for maintaining links when moving your domain name over to Tumblr.

Developers: Check out the Theme Docs for instructions on implementing the new {block:Pages} tag.

Once again, Tumblr’s brought the platform to a whole new level. Can’t wait to test it out.
