	73	+In order to fix a cache issue related to attachment, we change the behaviour of [[##Document#getAttachmentURL##>>http://nexus.xwiki.org/nexus/service/local/repositories/public/archive/org/xwiki/platform/xwiki-platform-oldcore/11.3/xwiki-platform-oldcore-11.3-javadoc.jar/!/com/xpn/xwiki/api/Document.html#getAttachmentURL-java.lang.String-]] methods.
	74	+
	75	+Those methods now return by default [[a ##downloadrev## URL>>Documentation.DevGuide.Architecture.URL Architecture.Standard URL Format||anchor="HAction:downloadrev"]] containing a query parameter part.
	76	+
	77	+If you want to add a query parameter for the returned URL, please don't append it to the returned URL, but [[use the dedicated API>>http://nexus.xwiki.org/nexus/service/local/repositories/public/archive/org/xwiki/platform/xwiki-platform-oldcore/11.3/xwiki-platform-oldcore-11.3-javadoc.jar/!/com/xpn/xwiki/api/Document.html#getAttachmentURL-java.lang.String-java.lang.String-java.lang.String-]].
