IPPS FFT Initialization has changed (Headers vs. Documentation)

I don't know when, but obviously did the Initialization of the IPPS FFT functions change.

ippsFFTInitAlloc is no longer available.

The current initialization process using

ippsFFTInit_R_32f,
                   ( IppsFFTSpec_R_32f** ppFFTSpec,
                     int order, int flag, IppHintAlgorithm hint,
                     Ipp8u* pSpec, Ipp8u* pSpecBuffer ))

is not clear and also not documented (the documentation still refers to the deprecated ippsFFTInitAlloc).

Any thoughts? Thanks!
