This is better discussed in the Apple Developer Tiger forums that you have access to if you are a registered developer [who has the right to download Tiger]. This way you don't accidentally disclose information here that is covered under the NDA you had to sign to get the pre-release software.
It looks like you can download a new version (8A325) right now... but if you do, don't go talking about it around here or the Apple Ninjas will swoop down and take you out like yesterday's garbage.
