- implemented generic item_refs: Item_refs are symbolic references to content items, stored in the xowiki folder or below (under pages or other folders). The item_refs are currently only used for internal links (between [[...]]), but will be used on other places as well (refering to included pages, refering to variable of other pages, etc.) - adjusted Link resolver logic to use item_refs (typed links (like the glossary link) are currently not supported) Item names with slashes are not allowed anymore! - remove old package parameter "top_portlet" - update dependencies - bump version number
