We've recently added a new page type -- the Variable page -- and additional options for item pages. These options, combined with a new format option (pretty_url_encode/decode), allow you to use almost any URL structure for your database-driven pages, and also to eliminate database IDs from URLs.

There's a new set of support articles that cover all this in detail:

• Customizing URL Generation (Overview)
• Using Custom Item Identifiers
• Using the Variable Page Type
