I just noticed Joomla 1.5.4 was released earlier this month

Joomla! 1.5.4 [Naiki] 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 on April 24, 2008. The Development Working Group’s goal is to continue to provide regular, frequent updates to the Joomla! community containing the latest bug fixes and minor enhancements.

So far I have really enjoyed working with Joomla version 1.5.x.  I’ve been integrating that with the Virtuemart shopping cart.  I think the guys at Virtuemart are doing a fantastic job, however there are many code tweaks that need to be made before you are able to realistically send any customers to your store.  Most of them are pretty small, but hopefully they will be fixed in near-future Virtuemart releases.  They seem so basic an obvious to me….
