Not bad for a .0.1 update. The announcements lists these features:
- Media Stems Export
- Rich XML Support
- Custom Starting Timecode
- Full-screen View in Lion
- One-step Transitions on Connected Clips
- GPU-accelerated export
- New Theme: Tribute
- Camera Import SDK
- Projects and Events on Xsan
About the Xsan support, Apple notes:
Create and edit your Final Cut Pro X projects and Events on Xsan. Ideal for multi-user workflows, you can import media through Final Cut Pro X and place it directly on the SAN. Multiple users can access the same source media, and each editor can create separate projects and Events on the SAN. Users can then edit from any system attached to the SAN, making it easy to move between computers and continue working.
So no shared timelines (wait! no timelines at all! I forgot.), but it sounds like the same Xsan support in prior versions of FCP.
Finally, and this is the first time I remember Apple doing this, they pre-announced two features. "Coming in early 2012: Multicam Editing, Broadcast-Quality Video Monitoring."
