Ok i didnt play some some weeks so my custom race from the beta 1 was still saved as defaulth when i selected custom race. it still got the abilities i had chosend back in beta 1.
The funny thing: i still got all the 15 ability points! So my custom race had +20% economy. when i spend more points in the same ability, the bonus even stacked! so i could get abilites like +100% popultaion growth. And at the sum could spend 25 ability points...
