There is a weird behavior with the tags 5.6.2, 5.6.3. and 5.6.4, I don't know if this is expected.
I'm having a problem trying to upgrade from 5.6.1. When I change the version to 5.6.2, 5.6.3. or 5.6.4 the org.got5.tapestry5.jquery.utils.JQueryUtils#merge method throws the exception: java.lang.NoSuchMethodError org.apache.tapestry5.json.JSONObject.get(Ljava/lang/String;)Ljava/lang/Object; and clearly the method with that signature doesn't exist anymore, that's fine, I can understand that and probably I'm not going to be able to go beyond this point in the upgrade. However when I go to to https://github.com/apache/tapestry-5/blob/5.6.4/tapestry-json/src/main/java/org/apache/tapestry5/json/JSONObject.java to see the new source code I see comments referencing the 5.7 version. Is that expected being in the 5.6.x?
