- by joni g.
JDK 8u20 has been released and is available from the Java Downloads page. See the JDK 8u20 Update Release Notes for details.
Highlights for this release:
The Medium security level has been removed. Now only High and Very High levels are available. Applets that do not conform with the latest security practices can still be authorized to run by adding the sites that host them to the Exception Site List. See Security for more information.
The javafxpackager tool has been renamed to javapackager, and supports both Java and JavaFX applications. The -B option has been added to the javapackager deploy command to enable arguments to be passed to the bundlers that are used to create self-contained applications. See javapackager for Windows or Linux and OS X for information.
The <fx:bundleArgument> helper parameter argument has been added to enable arguments to be passed to the bundlers when using ant tasks. See JavaFX Ant Task Reference for more information.
A new attribute is available for JAR file manifests. The Entry-Point attribute is used to identify the classes that are allowed to be used as entry points to your application. See Entry-Point Attribute for more information.
