Apple today seeded build 12D58 of OS X Mountain Lion 10.8.3 to developers, marking the seventh beta iteration of the newest version of Mountain Lion. 10.8.3 was first seeded to developers in November.
Build 12D58 comes a week after build 12D54, and like the previous build, contains no known issues or features. Build 12D54 brought significant changes to WiFi, and asked developers to focus on testing AirPlay, AirPort, Game Center, Graphics Drivers, and Safari.
9to5Mac notes that the new build again contains significant changes to WiFi, but additional changes are unknown. Registered developers can download the update on Apple’s Developer Page.
This post originally referred to Build 12D58 as the eighth developer seed of OS X 10.8.3 when it was actually the seventh seed.

The slow shutdown is not really a "bug". It's an inconvenience for some people who have it. Apple has a lot more serious issues to fix during these beta tests. Something like a slow shutdown would be on the bottom of their list.
The 10.8.3 update is recommended for all OS X Mountain Lion users and includes features and fixes that improve the stability, compatibility, and security of your Mac, including the following:
• The ability to redeem iTunes gift cards in the Mac App Store using your Mac's built-in camera
• Boot Camp support for installing Windows 8
• Boot Camp support for Macs with a 3TB hard drive
• A fix for an issue that may cause Logic Pro to become unresponsive when using certain plug-ins
• A fix for an issue that may cause audio to stutter on 2011 iMacs
• Includes Safari 6.0.3
It wasn't that long ago that I remember people complaining that rebooting to upgrade Safari or other system updates was literally like the end of the world because some folks had so much stuff open for their workflows they could not handle having to launch them all manually... Now OSX offers you the choice to have it do that for you as well.
It must be fixed and as a user i don't really care how or do you want the next generation Macs with OS X to shut down in 30 seconds out of the box because it's low priority?
Why do you assume it's an easy fix? Maybe it isn't.
