This release is mainly a maintenance release in order to be compatible with the Eclipse 3.0 release. There are only a few changes in the user interface concerning the editor preferences and the outline view, which shines with new symbols. Many thanks to Narushima Hironori who provided the gifs!
Like always there are two *alternative* ways of installation: download either the zip file and unzip to your eclipse installation or use the update site at http://rubyeclipse.sf.net/updatesite. You can find further information on our wiki at http://rubyeclipse.sf.net.
