Please rename files so there are no repeats. For example, README.md and
Readme.md would be the same file on Windows. In this test, you would get a
warning for "readme.md" because it makes everything lowercase. There are
repeats of these filename(s) with different casing:

# 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
