The syntax of the actions.xml file has not changed.

A few methods of the EditAction class were made final, since these three values must be known even if the action instance in question has not been loaded:

This change does not affect plugins that define actions using an actions.xml file. However, if your plugin creates action instances dynamically, you will need to make calls like the following instead of overriding these methods:

jEdit.setTemporaryProperty("action name.label",
    "Hello World");
jEdit.setTemporaryProperty("action name.toggle",
    "true or false");
jEdit.setTemporaryProperty("action name.mouse-over",
    "some string");

Make sure to use jEdit.setTemporaryProperty() and not jEdit.setProperty() since the latter will save the values to the user properties file, which is probably not what you want.

The jEdit.getActions() method has been deprecated, since it must load all plugin actions.xml files in order to return an array of EditAction instances. Use jEdit.getActionNames() instead, which returns an array of strings.

A new abstract method was added to the InputHandler class:

The removeKeyBinding() method of the DefaultInputHandler class has finally been implemented. Previously it always threw an InternalError when invoked.
