@@ -5,3 +5,4 @@ Changes to make to API when we are ready to make backward incompatible changes:
 - DataContentViewerHex and Strings can have the public setDataView methods removed in favor of the new private ones
 - Content.getUniquePath() should not thrown TskException.  We should deal with it in the method.
 - Make the list of events that Case fires off to be part of an enum to group them together (like IngestManager does). 
+- Sub-modules in RecentActivity have a bunch of public/protected variables that do not need to be. (i.e. ExtractRegistry.rrFullFound).
