Why trainbr function in Matlab 2010b doesn't present any information about validation check in nntraintool window?

I'm using trainbr function from Neural Network toolbox in Matlab2010b and the interface window (nntraintool) doesn't present any information about validation checks as I had before in previous Matlab version, for instance Matlab2008. In 2010b version, validation check is not executed as default when using trainbr function?

Validation Stopping and Regularization are alternative methods for mitigating the overtraining of an overfit network. (Others are to reduce the number of input and/or hidden nodes), See the comp.ai.neural-nets FAQ.

I guess they changed it because using both is overkill. However, I wish they hadn't.

Hope this helps.
