Today Apple released 10.8.2, the second major update to OS X Mountain Lion. To eliminate any potential issues, we generally recommend to update any supported systems using the standalone combo installer available from Apple.com, and not the built-in Software Update.
Be sure to back up any important data, and if possible clone your hard drive before applying the update. If you have any issues post-update, boot using Uni-beast.

What we know about 10.8.2 so far…

• 12.2.0 Darwin kernel
• Facebook integration
• Improved battery life for Mac laptops
• Updated AMD, Intel, and NVIDIA graphics drivers
• If you use customized or edited graphics kexts, it will be necessary to make the edits again using the new drivers as a base.
• If you OpenCL Enabler, reapply it before reboot
• If you’ve used the official 10.8.1 Nvidia drivers to fix glitchy Fermi cards, reapply the drivers before reboot
• Updated audio drivers
• You will have to reinstall the Patched AppleHDA using MultiBeast before rebooting.
• If you use VoodooHDA, you will not need to make any modifications

It's only fair to share...
