The Joomla! community is pleased to announce the immediate availability of Joomla! 1.5.4 [Naiki]. This is a normal maintenance release which includes a few low to moderate security issues, many bug fixes, and several very nice improvements. It has been a little over ten weeks since Joomla! 1.5.3 was released (content/view/4852/74/) on April 24, 2008. The Development Working Group (http://community.joomla.org/contributors/developers.html)'s goal is to continue to provide regular, frequent updates to the Joomla! community containing the latest bug fixes and minor enhancements.
