+# Release 0.12.0
+
+## Major Features and Improvements
+
+* TensorFlow now builds and runs on Microsoft Windows (tested on Windows 10,
+  Windows 7, and Windows Server 2016). Supported languages include Python (via a
+  pip package) and C++. CUDA 8.0 and cuDNN 5.1 are supported for GPU
+  acceleration. Known limitations include: It is not currently possible to load
+  a custom op library. The GCS and HDFS file systems are not currently
+  supported. The following ops are not currently implemented:
+  DepthwiseConv2dNative, DepthwiseConv2dNativeBackpropFilter,
+  DepthwiseConv2dNativeBackpropInput, Dequantize, Digamma, Erf, Erfc, Igamma,
+  Igammac, Lgamma, Polygamma, QuantizeAndDequantize, QuantizedAvgPool,
+  QuantizedBatchNomWithGlobalNormalization, QuantizedBiasAdd, QuantizedConcat,
+  QuantizedConv2D, QuantizedMatmul, QuantizedMaxPool,
+  QuantizeDownAndShrinkRange, QuantizedRelu, QuantizedRelu6, QuantizedReshape,
+  QuantizeV2, RequantizationRange, and Requantize.
+* Go: Experimental API in Go to create and execute graphs
+  (https://godoc.org/github.com/tensorflow/tensorflow/tensorflow/go)
+* New checkpoint format becomes the default in `tf.train.Saver`. Old V1
+  checkpoints continue to be readable; controlled by the `write_version`
+  argument, `tf.train.Saver` now by default writes out in the new V2
+  format. It significantly reduces the peak memory required and latency
+  incurred during restore.
+* Added a new library for library of matrix-free (iterative) solvers for linear
+  equations, linear least-squares, eigenvalues and singular values in
+  tensorflow/contrib/solvers. Initial version has lanczos bidiagonalization,
+  conjugate gradients and CGLS.
+* Added gradients for `matrix_solve_ls` and `self_adjoint_eig`.
+* Large cleanup to add second order gradient for ops with C++ gradients and
+  improve existing gradients such that most ops can now be differentiated
+  multiple times.
+* Added a solver for ordinary differential equations,
+  `tf.contrib.integrate.odeint`.
+* New contrib module for tensors with named axes, `tf.contrib.labeled_tensor`.
+* Visualization of embeddings in TensorBoard.
+
+## Breaking Changes to the API

   by adding .ok() to the call.

+* Renamed `tf.image.per_image_whitening()` to
+  `tf.image.per_image_standardization()`
+* Move Summary protobuf constructors to `tf.summary` submodule.
+* Deprecate `histogram_summary`, `audio_summary`, `scalar_summary`,
+  `image_summary`, `merge_summary`, and `merge_all_summaries`.
+* Combined `batch_*` and regular version of linear algebra and FFT ops. The
+  regular op now handles batches as well. All `batch_*` Python interfaces were
+  removed.
+* `tf.all_variables`, `tf.VARIABLES` and `tf.initialize_all_variables` renamed
+  to `tf.global_variables`, `tf.GLOBAL_VARIABLES` and
+  `tf.global_variables_initializer` respectively.
+
+## Bug Fixes and Other Changes
+
+* Use threadsafe version of `lgamma` function.
+* Fix `tf.sqrt` handling of negative arguments.
+* Fixed bug causing incorrect number of threads to be used for multi-threaded
+  benchmarks.
+* Performance optimizations for `batch_matmul` on multi-core CPUs.
+* Improve trace, `matrix_set_diag`, `matrix_diag_part` and their gradients to
+  work for rectangular matrices.
+* Support for SVD of complex valued matrices.
