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.

20
21* The Python API will now properly set the `list` member of `AttrValue` in
22 constructed `GraphDef` messages for empty lists. The serialization of some
23 graphs will change, but the change is both forwards and backwards compatible.
24 It will break tests that compare a generated `GraphDef` to a golden serialized
25 `GraphDef`.

30## Major Features and Improvements
31
32* Python 3.3+ support via changes to python codebase and ability
33 to specify python version via ./configure.
34
35* Some improvements to GPU performance and memory usage:
36 [convnet benchmarks](https://github.com/soumith/convnet-benchmarks/issues/66)
37 roughly equivalent with native cudnn v2 performance. Improvements mostly due
38 to moving to 32-bit indices, faster shuffling kernels. More improvements to
39 come in later releases.

41
42## Bug fixes
43
44* Lots of fixes to documentation and tutorials, many contributed
45 by the public.
46
47* 271 closed issues on github issues.
48
49## Backwards-incompatible changes
50
51* tf.nn.fixed_unigram_candidate_sampler changed its default 'distortion'
52 attribute from 0.0 to 1.0. This was a bug in the original release
53 that is now fixed.
