Keyword argument error in optim.RMSprop()

Hi, I am trying to implement a optimizer of RMSprop type.
The optimizer is initialized as follows:
optimizer = torch.optim.RMSprop(model.parameters(), alpha = 0.95, eps = 0.0001, centered = True)
Then I got the following error:
init() got an unexpected keyword argument ‘centered’

I am wondering is there any change made to the RMSprop so that it no longer support centered version ?

the centered option is in master but not in 0.1.10. It is due to appear in 0.1.11 today/tomorrow.
