Joomla 1.5 stable
Joomla 1.5 is now officially "stable" (it has been for a few days, but we just noticed today). Some early poke-and-prod testing indicates it should be up to the task of being 10stripe's CMS. Expect to see more about this soon.
On a related note, I have to say I am extremely disappointed that Joomla 1.5 seems to have carried over the "use a table for everything" disease. The page source for the default homepage is a really impressive disaster. Hopefully we will be able to coerce it into doing the Right Thing.
