jetpack writes to make sure we're aware that Apple's OS X 10.5.2 update is available and that it contains plenty of improvements and fixes that users have been asking for. Macworld enumerates some of the big ones, saying that the update "shows Apple listens to users" (sometimes). A couple of the new features simply restore Tiger (10.4) capabilities that Leopard (10.5) had inexplicably withdrawn. You can now shut off the much-maligned transparency of the menu bar, and organize your Dock stacks hierarchically and display them as folders. And Apple has provided welcome access to common Time Machine functions in the menu bar.
