The Joomla! 1.0 life comes to an end. Joomla! existed since August 2005 but is itself derived from Mambo 4.5.2 which in the original version 4.5 was finished in 2003.
Joomla! 1.5 is released early in 2008, now 14 versions and 7 million downloads later, we can speak of a general acceptance of this new version, which is also reflected in the availability of numerous native Joomla! 1.5 extensions. The extensions for Joomla! 1.0 are no longer available on http://extensions.joomla.org.
There is no more reason not to upgrade, especially if you know that on July 22, 2009 the official support of Joomla! 1.0 stops. So, be aware, no more security patches.
