> breeze 0.12 has been released for more than half a year, and it brings lots 
> of new features, performance improvement and bug fixes.
> One of the biggest features is LBFGS-B which is an implementation of LBFGS 
> with box constraints and much faster for some special case.
> We would like to implement Huber loss function for {{LinearRegression}} 
> (SPARK-3181) and it requires LBFGS-B as the optimization solver. So we should 
> bump up the dependent breeze version to 0.12.
> For more features, improvements and bug fixes of breeze 0.12, you can refer 
> the following link:
