 Old Release Notes
 =================
 
+Theano 0.10.0beta1 (9th of August, 2017)
+========================================
+
+This release contains a lot of bug fixes, improvements and new features to prepare the upcoming release candidate.
+
+We recommend that every developer updates to this version.
+
+Highlights:
+ - Moved Python 3.* minimum supported version from 3.3 to 3.4
+ - Replaced deprecated package ``nose-parameterized`` with up-to-date package ``parameterized`` for Theano requirements
+ - Theano now internally uses ``sha256`` instead of ``md5`` to work on systems that forbide ``md5`` for security reason
+ - Removed old GPU backend ``theano.sandbox.cuda``. New backend ``theano.gpuarray`` is now the official GPU backend
+ - Support more debuggers for ``PdbBreakpoint``
+
+ - Scan improvements
+
+   - Speed up Theano scan compilation and gradient computation
+   - Added meaningful message when missing inputs to scan
+
+ - Speed up graph toposort algorithm
+ - Faster C compilation by massively using a new interface for op params
+ - Faster optimization step
+ - Documentation updated and more complete
+ - Many bug fixes, crash fixes and warning improvements
+
+A total of 65 people contributed to this release since 0.9.0, see list below.
+
+Interface changes:
+ - Merged duplicated diagonal functions into two ops: ``ExtractDiag`` (extract a diagonal to a vector),
+   and ``AllocDiag`` (set a vector as a diagonal of an empty array)
+ - Renamed ``MultinomialWOReplacementFromUniform`` to ``ChoiceFromUniform``
+
+ - Removed or deprecated Theano flags:

+   - ``gpuarray.sync``
+   - ``home``
+   - ``lib.cnmem``

+
+ - Changed ``grad()`` method to ``L_op()`` in ops that need the outputs to compute gradient
+
+Convolution updates:
+ - Extended Theano flag ``dnn.enabled`` with new option ``no_check`` to help speed up cuDNN importation
+ - Implemented separable convolutions
+ - Implemented grouped convolutions
+
+GPU:
+ - Prevent GPU initialization when not required
+ - Added disk caching option for kernels
+ - Added method ``my_theano_function.sync_shared()`` to help synchronize GPU Theano functions
+ - Added useful stats for GPU in profile mode

+   SVD, matrix inverse, QR, cholesky and eigh
+ - Added ``GpuCublasTriangularSolve``
+ - Added atomic addition and exchange for ``long long`` values in ``GpuAdvancedIncSubtensor1_dev20``
+ - Support log gamma function for all non-complex types

+   - Support cuDNN v6 dilated convolutions
+   - Support cuDNN v6 reductions
+   - Added new Theano flags ``cuda.include_path``, ``dnn.base_path`` and ``dnn.bin_path``
+     to help configure Theano when CUDA and cuDNN can not be found automatically.
+
+ - Updated ``float16`` support
+
+   - Added documentation for GPU float16 ops
+   - Support ``float16`` for ``GpuGemmBatch``
+   - Started to use ``float32`` precision for computations that don't support ``float16`` on GPU
+
+New features:
+ - Added a wrapper for `Baidu's CTC <https://github.com/baidu-research/warp-ctc>`_ cost and gradient functions
+ - Added scalar and elemwise CPU ops for modified Bessel function of order 0 and 1 from ``scipy.special``.
+ - Added Scaled Exponential Linear Unit (SELU) activation

+ - Added new Theano flag ``deterministic`` to help control how Theano optimize certain ops that have deterministic versions.
+   Currently used for subtensor Ops only.
+ - Added new Theano flag ``cycle_detection`` to speed-up optimization step by reducing time spending in inplace optimizations
+ - Added new Theano flag ``check_stack_trace`` to help check the stack trace during optimization process
+ - Added new Theano flag ``cmodule.debug`` to allow a debug mode for Theano C code. Currently used for cuDNN convolutions only.
+
+Others:
+ - Added deprecation warning for the softmax and logsoftmax vector case
+ - Added a warning to announce that C++ compiler will become mandatory in next Theano release ``0.11``
+
+Other more detailed changes:

+ - Removed ``theano/compat/six.py``

+ - Started to move C code files into separate folder ``c_code`` in every Theano module
+ - Many improvements for Travis CI tests (with better splitting for faster testing)
+ - Many improvements for Jenkins CI tests: daily testings on Mac and Windows in addition to Linux
