- Division and modulus operators (/, //, %) now match Python (flooring) semantics. tf.div is renamed to tf.division. New operators tf.truncatediv and tf.truncatemod are available for achieving the previous C++ (truncation) division/modulus semantics.
- 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 thewrite_versionargument,tf.train.Savernow 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_lsandself_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.
BusAdjacencyenum replaced with a protocol bufferDeviceLocality. PCI bus indexing now starts from 1 instead of 0, and bus_id==0 is used where previously BUS_ANY was used.Env::FileExistsandFileSystem::FileExistsnow return a tensorflow::Status intead of a bool. Any callers to this function can be converted to a bool by adding .ok() to the call.- The C API type
TF_SessionWithGraphhas been renamed toTF_Session, indicating its preferred use in language bindings for TensorFlow. What was previouslyTF_Sessionhas been renamed toTF_DeprecatedSession. - Renamed TF_Port to TF_Output in the C API.
- Removes RegisterShape from public API. Use C++ shape function registration instead.
indexing now starts from 1 instead of 0, and
bus_id==0is used where previouslyBUS_ANYwas used. - Most RNN cells and RNN functions now use different variable scopes to be
consistent with layers (
tf.contrib.layers). This means old checkpoints written using this code will not load after this change without providingSavera list of variable renames. Examples of variable scope changes includeRNN->rnnintf.nn.rnn,tf.nn.dynamic_rnnand moving fromLinear/Matrix->weightsandLinear/Bias->biasesin most RNN cells. - Deprecated tf.select op. tf.where should be used instead.
Env::FileExistsandFileSystem::FileExistsnow return atensorflow::Statusintead of a bool. Any callers to this function can be converted to a bool by adding.ok()to the call.- C API: Type
TF_SessionWithGraphhas been renamed toTF_Session, indicating its preferred use in language bindings for TensorFlow. What was previouslyTF_Sessionhas been renamed toTF_DeprecatedSession. - C API: Renamed
TF_PorttoTF_Output. - C API: The caller retains ownership of
TF_Tensorobjects provided toTF_Run,TF_SessionRun,TF_SetAttrTensoretc. - Renamed
tf.image.per_image_whitening()totf.image.per_image_standardization() - Move Summary protobuf constructors to
tf.summarysubmodule. - Deprecate
histogram_summary,audio_summary,scalar_summary,image_summary,merge_summary, andmerge_all_summaries. - Combined
batch_*and regular version of linear algebra and FFT ops. The regular op now handles batches as well. Allbatch_*Python interfaces were removed. tf.all_variables,tf.VARIABLESandtf.initialize_all_variablesrenamed totf.global_variables,tf.GLOBAL_VARIABLESandtf.global_variables_initializerrespectively.
- Use threadsafe version of
lgammafunction. - Fix
tf.sqrthandling of negative arguments. - Fixed bug causing incorrect number of threads to be used for multi-threaded benchmarks.
- Performance optimizations for
batch_matmulon multi-core CPUs. - Improve trace,
matrix_set_diag,matrix_diag_partand their gradients to work for rectangular matrices. - Support for SVD of complex valued matrices.

- CUDA 8 support.
- cuDNN 5 support.
- HDFS Support.
- Adds Fused LSTM support via cuDNN 5 in
tensorflow/contrib/cudnn_rnn. - Improved support for NumPy style basic slicing including non-1 strides,
ellipses, newaxis, and negative indices. For example complicated expressions
like
foo[1, 2:4, tf.newaxis, ..., :-3:-1, :]are now supported. In addition we have preliminary (non-broadcasting) support for sliced assignment to variables. In particular one can writevar[1:3].assign([1,11,111]). - Deprecated
tf.op_scopeandtf.variable_op_scopein favor of a unifiedtf.name_scopeandtf.variable_scope. The new argument order oftf.variable_scopeis incompatible with previous versions. - Introducing
core/util/tensor_bundlemodule: a module to efficiently serialize/deserialize tensors to disk. Will be used in TF's new checkpoint format. - Added tf.svd for computing the singular value decomposition (SVD) of dense matrices or batches of matrices (CPU only).
- Added gradients for eigenvalues and eigenvectors computed using
self_adjoint_eigorself_adjoint_eigvals. - Eliminated
batch_*methods for most linear algebra and FFT ops and promoted the non-batch version of the ops to handle batches of matrices. - Tracing/timeline support for distributed runtime (no GPU profiler yet).
- C API gives access to inferred shapes with
TF_GraphGetTensorNumDimsandTF_GraphGetTensorShape. - Shape functions for core ops have moved to C++ via
REGISTER_OP(...).SetShapeFn(...). Python shape inference RegisterShape calls use the C++ shape functions withcommon_shapes.call_cpp_shape_fn. A future release will removeRegisterShapefrom python.
- Documentation now includes operator overloads on Tensor and Variable.
tensorflow.__git_version__now allows users to identify the version of the code that TensorFlow was compiled with. We also havetensorflow.__git_compiler__which identifies the compiler used to compile TensorFlow's core.- Improved multi-threaded performance of
batch_matmul. - LSTMCell, BasicLSTMCell, and MultiRNNCell constructors now default to
state_is_tuple=True. For a quick fix while transitioning to the new default, simply pass the argumentstate_is_tuple=False. - DeviceFactory's AddDevices and CreateDevices functions now return a Status instead of void.
- Int32 elements of list(type) arguments are no longer placed in host memory by default. If necessary, a list(type) argument to a kernel can be placed in host memory using a HostMemory annotation.
uniform_unit_scaling_initializer()no longer takes afull_shapearg, instead relying on the partition info passed to the initializer function when it's called.- The NodeDef protocol message is now defined in its own file
node_def.protoinstead of graph.proto. ops.NoGradientwas renamedops.NotDifferentiable.ops.NoGradientwill be removed soon.dot.h/ DotGraph was removed (it was an early analysis tool prior to TensorBoard, no longer that useful). It remains in history should someone find the code useful.- re2 / regexp.h was removed from being a public interface of TF. Should users need regular expressions, they should depend on the RE2 library directly rather than via TensorFlow.

*fft,*_matrix_solve) - Support for more data types in many ops
- Performance improvements
- Various bugfixes
- Documentation fixes and improvements
AdjustContrastkernel deprecated, new kernelAdjustContrastv2takes and outputs float only.adjust_contrastnow takes all data types.adjust_brightness'sdeltaargument is now always assumed to be in[0,1](as is the norm for images in floating point formats), independent of the data type of the input image.- The image processing ops do not take
minandmaxinputs any more, casting safety is handled bysaturate_cast, which makes sure over- and underflows are handled before casting to data types with smaller ranges. - For C++ API users:
IsLegacyScalarandIsLegacyVectorare now gone fromTensorShapeUtilssince TensorFlow is scalar strict within Google (for example, the shape argument totf.reshapecan't be a scalar anymore). The open source release was already scalar strict, so outside GoogleIsScalarandIsVectorare exact replacements. - The following files are being removed from
tensorflow/core/public/:env.h->../platform/env.hstatus.h->../lib/core/status.htensor.h->../framework/tensor.htensor_shape.h->../framework/tensor_shape.hpartial_tensor_shape.h->../framework/partial_tensor_shape.htensorflow_server.hdeleted
- For C++ API users:
TensorShape::ShortDebugStringhas been renamed toDebugString, and the previousDebugStringbehavior is gone (it was needlessly verbose and produced a confusing empty string for scalars). GraphOptions.skip_common_subexpression_eliminationhas been removed. All graph optimizer options are now specified viaGraphOptions.OptimizerOptions.ASSERT_OK/EXPECT_OKmacros conflicted with external projects, so they were renamedTF_ASSERT_OK,TF_EXPECT_OK. The existing macros are currently maintained for short-term compatibility but will be removed.- The non-public
nn.rnnand the variousnn.seq2seqmethods now return just the final state instead of the list of all states. tf.scatter_updatenow no longer guarantees that lexicographically largest index be used for update when duplicate entries exist.tf.image.random_crop(image, [height, width])is nowtf.random_crop(image, [height, width, depth]), andtf.random_cropworks for any rank (not just 3-D images). The C++RandomCropop has been replaced with pure Python.- Renamed
tf.test.GetTempDirandtf.test.IsBuiltWithCudatotf.test.get_temp_dirandtf.test.is_built_with_cudafor PEP-8 compatibility. parse_example's interface has changed, the old interface is accessible inlegacy_parse_example(same for related functions).- New
Variables are not added to the same collection several times even if a list with duplicates is passed to the constructor. - The Python API will now properly set the
listmember ofAttrValuein constructedGraphDefmessages for empty lists. The serialization of some graphs will change, but the change is both forwards and backwards compatible. It will break tests that compare a generatedGraphDefto a golden serializedGraphDef(which is discouraged).

-
Python 3.3+ support via changes to python codebase and ability to specify python version via ./configure.
-
Some improvements to GPU performance and memory usage: convnet benchmarks roughly equivalent with native cudnn v2 performance. Improvements mostly due to moving to 32-bit indices, faster shuffling kernels. More improvements to come in later releases.
-
Lots of fixes to documentation and tutorials, many contributed by the public.
-
271 closed issues on github issues.
tf.nn.fixed_unigram_candidate_samplerchanged its default 'distortion' attribute from 0.0 to 1.0. This was a bug in the original release that is now fixed.
Initial release of TensorFlow.
