Today's earlier iLife updates are a sign that Lion is set to drop any day now. Not only do the updates add full-screen support to the iLife apps under the latest Lion Developer Preview release, they also tweak some UI elements of iPhoto to match the upcoming UI Finder elements found in OS X 10.7.
The image shows a side-by-side comparison of the source list of iPhoto '11 (version 9.1.4) and iPhoto '11 (version 9.1.5). Both are running under Mac OS X 10.6.8. Gone are the colorful icons designating Events, Photos, Faces, and Places. They've all been replaced with grayed-out counterparts that mimic the look of the Finder's source list in Lion.
The source list in iWeb has retained its color icons, though that's no surprise as iWeb (and most likely iDVD) has no future as part of the iLife suite and their minor updates today were solely focused on 10.7 compatibility.
