After months of development and anticipation, Apple has released OS 10.5.2 (Patio, you can finally upgrade to Leopard!)
You can read about the update here:

A large number of minor bugs are addressed by this update, along with a smaller number of larger issues.
Important -Read before installing:
Apple strongly recommends that you back up your system prior to installing any updates.
They also say that “the installation process should not be interrupted, even if the progress bar remains unchanged for several minutes. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Support Downloads to update.
You may experience unexpected results if you have third-party system software modifications installed, or if you’ve modified the operating system through other means. (This does not apply to normal application software installation.)
If issues occur during installation—for example, if Software Update quits unexpectedly—please see this article:
http://docs.info.apple.com/article.html?artnum=106695
To update to Mac OS X 10.5.2, use Software Update or the standalone installer. You only need to use one of these methods to update your computer.
Software Update
Choose Software Update from the Apple menu to automatically check for the latest Apple software using the Internet, including this update. (Software Update might have linked you to this article to learn more about the update.) If your computer is not up-to-date, other software updates available for your computer may appear that you should install. Note that an update’s size may vary from computer to computer when installed using Software Update. Also, some updates must be installed prior to others, so you should run Software Update more than once to make sure you have all available updates.
Standalone installer
You can download the update installer and run it manually if you don’t want to use Software Update. The standalone installer is a useful option when you need to update multiple computers but only want to download the update once. The Mac OS X 10.5.2 Update standalone installer is available from Apple Support Downloads here:

This update delivers several improvements for both PowerPC- and Intel-based Macs (as well as improvements provided in the Mac OS X 10.5.1 update.)
