Apple has posted some details on the various conference sessions that will be available at the Worldwide Developer's Conference 2007.

The sessions are divided into 6 tracks:

- Leopard Innovations
- Mac OS X Essentials
- Information Technologies
- Developer Tools
- Graphics and Imaging
- Content and Media

The Leopard session descriptions are not particularly revealing, but does remind us of some upcoming features of Leopard that have previously been revealed:

- Core Animation is an incredible layer-based animation system that will revolutionize the user experience of your application.
- Mac OS X Leopard elevates video communication with iChat Theater, a new API that shares content from your application over video chat.
- The Calendar Store framework, provided in Mac OS X Leopard, is a simple interface to a user's iCal data. Using the Calendar Store, applications can read, create, and modify events and tasks with just a few lines of code.

An original overview of Leopard remains posted on Apple's site, but Steve Jobs hinted in August 2006 that several "top secret" features of Mac OS X 10.5 (Leopard) were being held back in Leopard and would not be revealed until a later date. Very few details about these secret features have been leaked to date, but many have speculated on significant visual changes to finder.

Leopard has been targeted for a "Spring 2007" release. WWDC 2007 takes place between June 11-15th in San Francisco.
