Well, maybe this post is too late 
But, Ubuntu 8.04 aka Hardy Heron has been released on 24 April 2008. For Indonesian Ubuntu users, the ISO files can be downloaded from http://kambing.ui.edu/pub/ubuntu/ or ftp://dl2.foss-id.web.id/iso/ubuntu/
There will be some Hardy Release Party across Indonesia soon.
Happy Hardy Heron!
