3## Breaking changes to the API
4
5* `AdjustContrast` kernel deprecated, new kernel `AdjustContrastv2` takes and
6 outputs float only. `adjust_contrast` now takes all data types.
7* `adjust_brightness`'s `delta` argument is now always assumed to be in `[0,1]`
8 (as is the norm for images in floating point formats), independent of the
9 data type of the input image.
10* The image processing ops do not take `min` and `max` inputs any more, casting
11 safety is handled by `saturate_cast`, which makes sure over- and underflows
12 are handled before casting to data types with smaller ranges.
Geoffrey Irvingcbff45c2016-01-12 08:06:56 -080013* For C++ API users: `IsLegacyScalar` and `IsLegacyVector` are now gone from
14 `TensorShapeUtils` since TensorFlow is scalar strict within Google (for
15 example, the shape argument to `tf.reshape` can't be a scalar anymore). The
16 open source release was already scalar strict, so outside Google `IsScalar`
17 and `IsVector` are exact replacements.
Josh Levenbergdb7478e2016-01-20 14:54:50 -080018* The following files are being removed from `tensorflow/core/public/`:
19 * `env.h` -> `../platform/env.h`
20 * `status.h` -> `../lib/core/status.h`
21 * `tensor.h` -> `../framework/tensor.h`
22 * `tensor_shape.h` -> `../framework/tensor_shape.h`
23 * `partial_tensor_shape.h` -> `../framework/partial_tensor_shape.h`
24 * `tensorflow_server.h` deleted
Geoffrey Irving56437752016-01-25 09:43:13 -080025* For C++ API users: `TensorShape::ShortDebugString` has been renamed to
26 `DebugString`, and the previous `DebugString` behavior is gone (it was
27 needlessly verbose and produced a confusing empty string for scalars).

Josh Levenberg02dff6d2016-01-07 18:37:54 -080030## Bug fixes
31
32* The Python API will now properly set the `list` member of `AttrValue` in
33 constructed `GraphDef` messages for empty lists. The serialization of some
34 graphs will change, but the change is both forwards and backwards compatible.
35 It will break tests that compare a generated `GraphDef` to a golden serialized
36 `GraphDef`.

41## Major Features and Improvements
42
43* Python 3.3+ support via changes to python codebase and ability
44 to specify python version via ./configure.
45
46* Some improvements to GPU performance and memory usage:
47 [convnet benchmarks](https://github.com/soumith/convnet-benchmarks/issues/66)
48 roughly equivalent with native cudnn v2 performance. Improvements mostly due
49 to moving to 32-bit indices, faster shuffling kernels. More improvements to
50 come in later releases.
51
52
53## Bug fixes
54
55* Lots of fixes to documentation and tutorials, many contributed
56 by the public.
57
58* 271 closed issues on github issues.
59
60## Backwards-incompatible changes
61
62* tf.nn.fixed_unigram_candidate_sampler changed its default 'distortion'
63 attribute from 0.0 to 1.0. This was a bug in the original release
64 that is now fixed.
