Just five days after Apple released Snow Leopard dev build 10A402a, we now have another new release in Snow Leopard Developer Preview Update 10A411. This latest update is 748MB in size, and according to Apple, includes “general operating system fixes for stability, compatibility, and security.”  Getting a bit more specific though, a reader on the MacRumors forums has pinpointed a few changes:

• Dock Expose now previews windows from other spaces.
• Expose’s animations are very smooth now. I think they sped up the animation, so the user’s perception of the OS is visually faster as well.
• In the Desktop & Screen Saver preference pane, selecting “Change picture every…” and then “Random Order” does not select a random photo at first—the first photo will always be selected.
• A bug is still present where applications do not retain proper focus when activating spaces. For instance, this Safari window is in focus, and a Preference Pane is opened behind it. Start spaces—and the pane appears on top.
• No put back for items trashed from Dock or stacks.
• Updated QuickTime.
• Items can now be dragged to trash from stacks.
• Trashed desktop items no longer fade away.

Once again, the update is available through Software Update, so have at it.
