The new version of Opendelight, version 1.1, has been released today and is available for download.
This version carries only bug fixes since the time we released 1.0. The issues include wrong object reference in install file and error throwing due to argument incompatibility at loader in certain PHP environments. With the change of URL of the feed URL, the requisite modifications have also been done to feed URL fetch method on IDE.
