Yes I know PHP 5.4 just came out, and yes I know PHP 5.3 has lovely features, but there are plenty of corporate systems running on CodeIgniter and PHP 5.3 still is not widely supported enough. CodeIgniter is great for distributed applications, and this is the highest we can reasonably go without breaking support. PHP 5.3 will most likely happen in another year or so.
