@section S2_1_versions Release versions

All releases are numbered vYY.MM Where YY are the last two digits of the year, and MM the month number.
If there is more than one release in a month then an extra sequential number is appended at the end:

	v17.03 (First release of March 2017)
	v17.03.1 (Second release of March 2017)

 - Deprecated functions / interfaces:
   - Non-descriptor based interfaces for NEThreshold, CLThreshold
   - Non-descriptor based interfaces for @ref NEScale, @ref CLScale and GCScale
   - In @ref NESoftmaxLayer, @ref NELogSoftmaxLayer, @ref CLSoftmaxLayer, @ref CLLogSoftmaxLayer and GCSoftmaxLayer :
      The default "axis" value for @ref CLSoftmaxLayer, @ref CLLogSoftmaxLayer and GCSoftmaxLayer is changed from 1 to 0.
      Only axis 0 is supported.
      The default "axis" value for @ref NESoftmaxLayer, @ref NELogSoftmaxLayer is changed from 1 to 0.
      Only axis 0 is supported.
 - The support for quantized data types has been removed from @ref CLLogSoftmaxLayer due to implementation complexity.

   - This support allows to export the OpenCL buffer used for the reshaped RHS matrix to the OpenCL image object.
   - The padding requirement for the OpenCL image object is considered into the CLGEMMReshapeRHSMatrixKernel.
