WordPress Multi-user 1.0 has been released. WordPress MU is designed for hosting and managing hundreds or thousands of blogs, similar to WordPress.com. Setup of WordPress MU is considerably more difficult than setting up a stand-alone WordPress installation. Here’s some text from the post to the WordPress development blog:
WordPress MU is an official branch of WordPress that is designed for managing and hosting thousands of blogs instead of just one. It’s the software that powers WordPress.com, for example. MU has been in heavy development for about a year now, and we’ve finally polished it up to a place where we feel like it’s ready for public consumption. Since setup is a bit more complex than the 5-minute install of regular WordPress, MU is best suited for a more server-savvy audience. You can download it on the WordPress MU site.
bbPress 0.72 was also released. bbPress is a piece of forum software “with the WordPress touch”.
Head on over to the WordPress Development blog for more info on both of these products.
