I was starting to write with the CMSIS-DSP stuff and noticed the library (ie. arm_math.h) is version 1.1.0 from Feb 2012.
This version is getting pretty old, I think the latest is 1.5.1 from Jan 2017.
I'm particularly interested because it appears new, faster versions of the floating point FFTs are now available with the old ones being deprecated.
"The main functions are arm_rfft_fast_f32() and arm_rfft_fast_init_f32(). The older functions arm_rfft_f32() and arm_rfft_init_f32() have been deprecated but are still documented."

These 'fast' functions do not appear to be available in the older 1.1.0.
