Today we get an iLife '09 update, and a bunch of camera RAW updates.
Here's what Apple has to say about the iLife update:
Provides system software resources that are shared by iLife and other applications. This update improves overall stability for the Media Browser and iPhoto slideshows. It also provides compatibility between Aperture 3 and the Media Browser.
The update is recommended for all users of iLife '09, iWork '09, and Aperture.
And the camera updates:
This update extends RAW image compatibility for Aperture 3 and iPhoto '09 for the following cameras and formats:
Canon PowerShot S90
Leica D-LUX 4
Panasonic Lumix DMC-G1
Panasonic Lumix DMC-GH1
Panasonic Lumix DMC-LX3
It's not earthshaking, but will be welcome for heavy iLife '09 users. You can get these from the software update option under the Apple menu.
