• Improvements to documentation
• Added arm_fir_decimate_f64
• Removed some gcc workarounds that are no more needed for Helium
• Removed redundant test in arm_atan2_q15 and arm_atan2_q31
• Replaced INFINITY by maximum positive float
• Replaced hex constants with 2's complement equivalents
• Added C++ template extension (outside of pack - headers available from github repository)
• Added new compilation defines (ARM_DSP_ATTRIBUTE, ARM_DSP_TABLE_ATTRIBUTE and ARM_DSP_CUSTOM_CONFIG)
• Solved several github issues
• Corrected wrong version number in pack for v1.16.0
• Corrected issue #201 in v1.16.1 (related to new ARM_DSP_ATTRIBUTE)

• Switched to semantic versioning
• Corrections to MFCC
• Updated support for cmsis build tools 2.0
• Compute graph removed. It is now part of CMSIS-Stream
• Github issues:
  • 95,96,105,106,108,111,112
• New FFT initializations to allow linker to do code size optimizations
  • If you know the size of the transform at build time, prefer functions like
    arm_cfft_init_64_q15 to functions like arm_cfft_init_q15.
    It applies for CFFT, RFFT and MFCC and other datatypes.
