Where is PSR-4 episode?

Phil mentioned episode covering PSR-4. (at http://teamtreehouse.com/library/standards-and-best-practices/autoloading-and-composer/composer ) But I can't find next episode. Where is it?

I just finished the course and didn't see anything else about PSR-4. You can check out the documentation here. Mostly, PSR-4 is exactly like PSR-0, but underscores in the name space no longer represent directories. For example:

<?php
// PSR-0 namespace with underscores
use \namespace\package\Class_Name 
// gets file at /path/to/project/lib/vendor/namespace/package/Class/Name.php

//PSR-4 namespace with underscore
use \namespace\package\Class_Name 
// gets file at /path/to/project/lib/vendor/namespace/package/Class_Name.php

Hope this helps.
