UPDATE: Leopard build 9A321 is reportedly [1] adding an "Answering Machine" feature on iChat.

Early this week, Apple has seeded the build 9A321 of Mac OS X Leopard to developers.

The new build fixes several minor bugs and improves performance. No new features have been reported for this build.

A recent report claimed [2] that Apple will replace the Aqua user interface by a new one called "Illuminous". However, reports on Leopard's latest build don't mention any user interface changes.
