This release finally adds support to organize pages by tags with an index and a tag cloud widget in the side pane. Also pages are now moved to the system Trash instead of being deleted immediately. Other improvements include the support to open pages by clicking in the link map, controls to increase and decrease the editor font, and support for interwiki links when exporting to HTML. A critical bug was fixed for resizing images, as well as a bug with the auto-completion of pages in various dialogs. Plugins were added to insert plots based on GNUplot, and to sort text by line in the editor.
