This release features LiveConnect support with Safari, a new JFileChooser, integration with system proxy settings, and overall performance improvements. Please note that 1.4.2 completely replaces the current Java 1.4.1 implementation on Panther systems, and is not removableonce installed.

A developer preview of Java 1.4.2 Update 1 is also available to All ADC members via the ADC Member Site. Like the 1.4.2 release, the DP is not removable and will replace your current 1.4.x installation. Please limit installation of the previews to non-critical systems.
