 ! Introduction
 
-<<.from-version "5.1.23">> The ''action-log'' widget is an [[action widget|ActionWidgets]] that can be used to output debugging information to the JavaScript console supported by most browsers. This can be useful because otherwise it is difficult to observe what is going on within a sequence of actions.

 ! Content and Attributes
 
 The ''action-log'' widget is invisible. Any content within it is ignored.
 
 When the actions are invoked, the names and values of all attributes are logged to the JavaScript console.
+In addition there are optional attributes that can be used:

+|!Optional Attribute |!Description |
+|$$filter|All variables matching this filter will also be logged. |
