Late release of the Drupal 6 Branch (sorry !)
We reviewed and cleaned a lot of the code to make Basic cleaner and easier to work with when developing a new theme.
Layout.css is clearer and simpler, very easy to edit.
We also added the cache clearing from ZEN, very nice for development but remember to turn it off when the site is live, to save memory usage.
Since version 2, a new class have implemented to the body class : the browser class ! It adds a class corresponding to the browser viewing the page, so if you are using Firefox 3, the body class will be 'firefox3'. This might help for debugging some browsers without using any hacking.
Cleaner, simpler, better, easier, just more basic !
