In a recent post Justin Tadlock takes a look ahead and talks about the upcoming WordPress 3.0 version and some of what will come with it.
There's typically a ton of hype surrounding new WordPress releases, and WordPress 3.0 certainly won't be short of people singing its praises. This upcoming release might even have more hype than usual because the sheer number of new features will be overwhelming. When WordPress 3.0 is released, it'll mark the release of several things I've been waiting for in the last couple of years. It'll be at a point where it can be molded to create any type of website.
He talks about what things will make this release stand out from some of the ones in the past and what features with come with it including custom post types, improved navigation menu features, built-in shortlinks, custom headers/backgrounds and and more standardized comment form.
If I were to dub this release anything it'd be WordPress: Custom.
