Specifically, Apple said the 10.19MB update resolves issues with:
Transferring personal data, settings, and compatible applications from a Mac running Mac OS X Snow Leopard to a new Mac running Mac OS X Lion
Certain network printers that pause print jobs immediately and fail to complete
System audio that stops working when using HDMI or optical audio out
A similar 10.23MB update was released for Snow Leopard Server.
For those Macs that haven't yet moved to Snow Leopard version 10.6.8, Apple re-released its distributions of that point release with the supplemental fixes baked in:
Mac OS X 10.6.8 Update v.1.1 (453MB)
Mac OS X 10.6.8 Update Combo v1.1 (1.09GB)
Mac OS X Server v10.6.8 Update v1.1 (518MB)
Monday's releases would appear to be the final updates Apple has planned for the Snow Leopard operating system, with the company having released Mac OS X Lion last Wednesday.
