4.25 will give warnings whenever any of the WebHare 3.xx layout attributes are set in XML. The matching properties have also been completely removed in the HareScript components. These properties have never done anything useful in the new Tollium interface and will now be removed
To help you dealing with this, we’ve added experimental (screen) XML cleanup to the dev module.
wh dev:cleanupmodule --xml <modulename> should remove the obsolete attributes from XML and convert the XML file to a canonical structure while we’re at it.
(please note that this is about the border attribute - 4.x uses the borders attributes and that one’s going nowhere.
