First PSR-4 Autoloader Released: Aura.Autoload 2.0.0-beta1
I suppose it makes sense that since the the main author behind the PSR-4 Autoloader recommendation is also the lead on the Aura project, that Aura would have the first PSR-4 implementation. You can download it here
and you can find the README here (or in the download, of course):
I expect Composer will have support for PSR-4 soon as well.
