[FLOW3-general] magic methods changed in beta1?

[Heiko Kromm | Paints]

Hi list, 

in my test application I've used some magic methods findBy' findOneBy'. 
After upgrading to beta1 these methods return an empty 
F3\FLOW3\Persistence\Doctrine\QueryResult 

I found out, that findByUuid changed to findByIdentifier. Are there although changes to the magic methods? 

Thanks for your help 
Heiko
