We should be�restrained at the start of Pharo 4 development too because we firstly need to improve modularization of the system. It's common that at the start of the development cycle a huge amount of various modifications is integrated and often with only little regards on modularization. Then to improve the Pharo in this frontline is very hard and�ungrateful task.�
At the start of the new release we firstly need to change our system and integration tools to take this into account...
