Apple yesterday revealed 90 of its 140 proposed Worldwide Developers Conference 2005 sessions, with a particular focus on Mac OS X 10.4 "Tiger".

As anticipation that Apple is set to debut Tiger sooner rather than later mounts, the company has also upgraded its RSS feeds for developers. Tiger will include Safari RSS, which offers RSS newsreading capabilities.

Promising a "full-spectrum" experience, the company says: "With extensive coverage of Tiger and other cutting-edge Apple technologies, WWDC 2005 is certain to be the most important developer event of the year."

Topics promised at the conference include: a guide to the new features of .Mac in Tiger ("how to extend your application using the SDK's new APIs for Internet-based collaboration, workflow and security"); how to add syncing capabilities to applications; Xcode; Advanced Widgets and 86 more.

One of the listed sessions is highly promising. That session is called: "Building 64-bit Solutions for Tiger". "Learn the specifics of Tiger's 64-bit support and how to factor a Carbon or Cocoa application to run in conjunction with 64-bit backend processes," Apple says.

New developer documents released within the last 24-hours include: a technical Q&A on adding the ability to read and write Keynote 2 documents to an application; movie conversion without displaying a settings dialogue; optimizing OpenGL on Mac OS X.
