Apple has just released Java Update 2 for OS X 10.5. It’s 137 megabytes. I would recommend that everybody apply this update. It can be downloaded here.

This update also applies to OS X 10.4. This is update 7. This update is only 79 megabytes and is available from here.

Java updates are security updates and bug fixes.

All of the details, what little information is available, is located here.

This update is for OS X 10.4 or higher.

“This release updates Java SE 6 to version 1.6.0_07, J2SE 5.0 to version 1.5.0_16, and J2SE 1.4.2 to 1.4.2_18.”
