[voltan]

I think about use ZF3 on Pi, on zf3 package system changed and need load all files by Autoloader , did you check zf3 before?

what is your idea? can we update to zf3 easy?

Update loading system is important , for start we can update to zf2.5 ( or 2.6 / 2.7 ) and use new method for load zf2 , after that update to zf3 is easyer

I could update zf2.4 to zf2.5 :
1- Get zf2.5 by composer
2- relapse new folder by Zend folder
3- add this code on Pi\Application\Autoloader ( on __construct function or autoloadStandard ) => include Pi::path('lib/Zend/autoload.php'); ( set true path )

every things will work , after this update we will ready for work on zf3
