hi paolo,

i just saw this on the fftw homepage.


The FFTW Release Notes
This document describes the new features and changes in each release of FFTW.
FFTW 3.1
January 28, 2006

    * Faster FFTW_ESTIMATE planner.
    * New (faster) algorithm for REDFT00/RODFT00 (type-I DCT/DST) of odd size.
    * "4-step" algorithm for faster FFTs of very large sizes (> 2^18).
    * Faster in-place real-data DFTs (for R2HC and HC2R r2r formats).


looks active to me. :-)

ciao,
   axel.
