So how would you propose changes are made to an "API"? Never? The change was made in a new version, with the changes clearly laid out in the changelog .. what more do you want?
It's funny. PHP gets a bashing for the rotten bits .. when the rottern bits get patched up it gets a bashing for breaking BC.
Anyway, I don't think you understand just how empty that attack was. Frankly it was nothing more than the ramblings of an obviously very inexperienced developer.
