@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)
	v17.04 (First release of April 2017)

@note We're aiming at releasing one major public release with new features per quarter. All releases in between will only contain bug fixes.

v20.11 Public major release
 - Various bug fixes.
 - Various optimisations.
 - Performance regressions can be noted when executing Depthwise Convolution on Arm® Neon™ with a depth multiplier > 1 for quantized data type.

 - Removed OpenCL kernels / functions:
   - CLGEMMLowpQuantizeDownInt32ToUint8Scale
   - CLGEMMLowpQuantizeDownInt32ToUint8ScaleByFloat
 - Removed Arm® Neon™ kernels / functions:
   - NEGEMMLowpQuantizeDownInt32ToUint8Scale
   - NEGEMMMatrixAccumulateBiasesKernel
 - 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.
 - Removed padding requirement for the input (e.g. LHS of GEMM) and output in @ref CLGEMMMatrixMultiplyNativeKernel, @ref CLGEMMMatrixMultiplyReshapedKernel, @ref CLGEMMMatrixMultiplyReshapedOnlyRHSKernel and @ref CLIm2ColKernel (NHWC only)
   - This change allows to use @ref CLGEMMConvolutionLayer without extra padding for the input and output.
   - Only the weights/bias of @ref CLGEMMConvolutionLayer could require padding for the computation.
   - Only on Arm® Mali™ Midgard GPUs, @ref CLGEMMConvolutionLayer could require padding since @ref CLGEMMMatrixMultiplyKernel is called and currently requires padding.
 - Added support for exporting the OpenCL buffer object to the OpenCL image object in @ref CLGEMMMatrixMultiplyReshapedKernel and @ref CLGEMMMatrixMultiplyReshapedOnlyRHSKernel.
   - 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 @ref CLGEMMReshapeRHSMatrixKernel.
   - The reshaped RHS matrix stores the weights when GEMM is used to accelerate @ref CLGEMMConvolutionLayer.
