+TODO: better Theano conv doc
+
 Highlight:
+ - Many computation and compilation speed up
+ - More numerical stability by default for some graph
+ - Jenkins (gpu tests run on PR in addition to daily buildbot)
+ - More graph optimization (faster execution and smaller graph, so more readable)
+ - Less c code compilation
+ - Better Python 3.5 support
+ - Support newer Mac and Windows version
+ - Conda packages for Mac, Linux and Windows
+ - scan with checkpoint (trade off between speed and memory usage, useful for long sequences)
+ - Added a bool dtype

-Computation and compilation speed up
-Multi-cores convolution and pooling on CPU
-More numerical stability by default for some graph.
-New 3d convolution and pooling interface
-CuDNN: 5.1, batch normalization, RNN
-Dilated convolution
-Multiple-GPU, synchrone update (via platoon, use NCCL)
-Partial function evaluation
-Add gradient of solve, tensorinv (CPU), tensorsolve (CPU) searchsorted (CPU)
-Add Multinomial Without Replacement
-Pooling parameters can change at run time
-Jenkins (gpu tests run on PR in addition to daily buildbot)
+ - New back-end:
+   - float16 storage
+   - print pci bus id
+   - More pooling support on GPU when cudnn isn't there.

+Interface changes:
+ - New pooling interface
+ - Pooling parameters can change at run time
+ - When converting empty list/tuple, now we use floatX dtype
+ - The MRG random generator now try to infer the broadcast pattern of its output
+ - Move softsign out of sandbox to theano.tensor.nnet.softsign
+ - Roll make the shift be modulo the size of the axis we roll on

-Add DownsampleFactorMaxGradGrad.grad
-Better Python 3.5 support
-Mac, Windows new versions fixes
-More Rop support
-More stack trace in error message
-Speed up cholesky grad
-conv3d2d support full and half mode
-indexing support ellipsis a[..., 3], a[1,...,3]
+Convolution updates:
+ - Multi-cores convolution and pooling on CPU
+ - New abstract 3d convolution interface similar to the 2d convolution interface
+ - Dilated convolution

-Details
-Doc/error message fixes/updtes
-GpuJoin support negative axis.
-Move softsign out of sandbox to theano.tensor.nnet.softsign
-norm(keepdims) param added
-Add flag profiling.ignore_first_call
-More op in the new back-end.
-Crash fixes
-More graph optimizations
-tensor5, dtensor5...
-compiledir_format support device
-make scan grad more deterministic.
-Add support for space in path
-Roll make the shift be modulo the size of the axis we roll on

+GPU:
+ - CuDNN: support versoin 5.1 and wrap batch normalization (2d and 3d) and RNN functions
+ - Multiple-GPU, synchrone update (via platoon, use NCCL)
+ - GpuAdvancedSubtensor in new back-end
+ - Gemv(matrix-vector product) speed up for special shape
+ - Support for MaxAndArgMax for some axis combination
+ - cublas gemv workaround when we reduce on an axis with a dimensions size of 0
+
+New feature:
+ - Add gradient of solve, tensorinv (CPU), tensorsolve (CPU) searchsorted (CPU)
+ - Add Multinomial Without Replacement
+ - conv3d2d support full and half mode (REMOVE?)
+ - Add DownsampleFactorMaxGradGrad.grad
+ - Allow partial evaluation of compiled function
+ - More Rop support
+ - Indexing support ellipsis: a[..., 3], a[1,...,3]
+ - Added theano.tensor.{tensor5,dtensor5, ...}
+ - compiledir_format support device
+
+
+Others:
+ - Speed up argmax only on gpu (without also needing the max)
+ - A few unfrequent bugfix 
+ - More stack trace in error message
+ - Speed up cholesky grad
+ - log(sum(exp(...))) now get stability optimized


-ALL THE PR BELLOW HAVE BEEN CHECKED

+
+Other more detailed changes:
+ - Allow more then one output to be an destructive inplace
+ - Add flag profiling.ignore_first_call, useful to profile the new gpu back-end
+ - Doc/error message fixes/updates
+ - More support of negative axis
+ - Added the keepdims parameter to the norm function
+ - Crash fixes
+ - Make scan gradiant more deterministic
+ - Add support for space in path on Windows
+ - remove ProfileMode (use Theano flag profile=True instead)
