-1.0
+
+1.1 : (Jan 30,2004)
+    split sample_code/ into test/ and tools/
+
+    Removed 2-D fft and added N-D fft (arbitrary)
+
+    modified fftutil.c to allow multi-d FFTs
+
+    Modified core fft routine to allow an input stride via kiss_fft_stride()
+    (eased support of multi-D ffts)
+
+    Added fast convolution filtering (FIR filtering using overlap-scrap method, with tail scrap)
+
+    Add kfc.[ch]: the KISS FFT Cache. It takes care of allocs for you ( suggested by Oscar Lesta ).
+
+1.0.1 (Dec 15, 2003)
+    fixed bug that occurred when nfft==1
+    
+1.0 : (Dec 14, 2003)
     changed kiss_fft function from using a single buffer, to two buffers.
     If the same buffer pointer is supplied for both in and out, kiss will
     manage the buffer copies.
 
     added kiss_fft2d and kiss_fftr as separate source files (declarations in kiss_fft.h )
 
-0.4 : optimized for radix 2,3,4,5
+0.4 :(Nov 4,2003) optimized for radix 2,3,4,5
 
-0.3 : woops, version 2 didn't actually factor out any radices other than 2
+0.3 :(Oct 28, 2003) woops, version 2 didn't actually factor out any radices other than 2
 
-0.2 : added mixed radix, only radix 2,4 optimized versions
+0.2 :(Oct 27, 2003) added mixed radix, only radix 2,4 optimized versions
 
-0.1 :  initial release, radix 2 only
+0.1 :(May 19 2003)  initial release, radix 2 only
