- Sparse (in feature map dimension) convolutional layer added, with full support in CPU backend and fully connected (spatial) 1x1 support in GPU backend
- You can use -std=c++11 now with CUDA 6.5 toolkit
- Gradient check added
- GTSRB switched to batch training
- Boost and OpenCV libs default paths are /usr now
- Improved performance for 1x1 convolutions in GPU backend
- Minor fixes
