Release 0s                                                       October 1, 2000
      * New component: fird, a FIR filter designer, however with no
        psycho-acoustic stuff yet.
      * A quick hack: fconv, a fast convolver, ugly code lack of features and 
        so on, but can be used to demonstrate how much faster fast convolution 
	is than convolution in the time domain (which nwfiir does).
      * Fixed some Makefile stuff.

Release 0r                                                    September 16, 2000
      * Overall bugfixes
      * mls2imp: removed impulse response post-processing features
      * New component: impproc, for post-processing impulse responses.

Release 0q                                                       August 13, 2000
      * nwfiir: general optimisation of buffering code, as well as a few
        bugfixes in it.
      * mls2imp: added option for smoothing the impulse response. May be good
        if the measurement produces a noisy impulse response, but may also
	impact the fidelity.	

Release 0p                                                         June 17, 2000
      * nwfiir: ALSA pre-0.6 support updated, minor improvements of ALSA
        code.
      
Release 0o                                                         June 11, 2000
      * nwfiir: initial FIR filter support, requires MMX, and is very fast. 
        Support for ALSA pre-0.6 (hopefully, pre-0.6 ALSA API is not 
	frozen yet). Old ALSA code (for 0.5.8) included just in case.
      * wfird: minor optimisation when warp factor is set to zero (FIR design).
      * mls2imp: contains some extra dead code, but no new features.
      
Release 0n                                                        April 17, 2000
      * nwfiir: Buffering system rewritten to handle real-time operation in a
        more robust way, now there should be no sound skipping when using ALSA.
	
Release 0m                                                        March 18, 2000
      * nwfiir: ALSA support implemented (tested against 0.5.6). Added filter 
        calculation overflow detection and protection. Deactivating the filter 
	now works again.
	
Release 0l                                                        March 12, 2000
      * Programs that handle sampled data have got a more flexible way of 
        specifying the format (nwfiir, mlsgen, mls2imp).
      * wfird: phase cannot be converted to dB anymore :-)
      * mls2imp: excess phase and minimum phase options
      * nwfiir: pre-pre-preliminary FIR filter included, may not be in usable
        state. Prepared for ALSA support, although not yet implemented.
	Shared memory areas are now destroyed when nwfiir exits.

Release 0k                                                     December 12, 1999
      * mls2imp: averaging functionality removed, since it did not work, and 
        was shown unnecessary.
      * Various small bugs fixed.
      * The system has for the first time been tested for real room 
        equalisation, and been shown to work. This is likely the last release 
	before Release 1.

Release 0j                                                      December 5, 1999
      * wfird: autogain bug fixed.  Compability with GNU Scientific Library 
        version 0.5 verified (no changes were needed).

Release 0i                                                     November 21, 1999
      * nwfiir: fixed byte swap bug.
      * nwfiir: fixed double rate bug.
      * mlsgen: added feature to select tap set, to vary an MLS of the same 
        order.
      * wfird: fixed minor frequency mapping bug.
      * New component: mls2imp, converts an MLS response to an impulse response.

Release 0h                                                     November 17, 1999
      * mlsgen: fixed a bug that caused it to output negative signals.
      * mlsgen: simplified usage of it, removed unecessary options.

Release 0g                                                     November 14, 1999
      * nwfiir, wfird: fixed a parsing bug causing crashes on large input.
      * New component: a power response preprocessor, mspreproc. It is to be
        used to preprocess a measured power response prior to filter design.

Release 0f                                                     November 13, 1999
      * nwfiir: fixed a permission bug for shared memory.

Release 0e                                                      November 7, 1999
      * nwfiir: now possible to have other warp factors than 127/128, namely
        1/2, 3/4, 7/8 ... 255/256.
      * nwfiir: pthread implementation replaced with a solution using fork,
        to improve portability, and getting rid of a workaround needed due to
	poor realtime properties of LinuxThreads's pthread_cond_wait().

Release 0d                                                      November 1, 1999
      * mlsgen: fatal bug that caused it to output incorrect mls signals fixed.
      * mlsgen: increased the maximum possible mls order from 16 to 24.
      
Release 0c                                                      October 31, 1999
      * A component of the measuring system is included, an MLS (Maximum Length
        Sequence) generator.

Release 0b                                                      October 27, 1999

      * wfird: automatic gain adjustment of the filter power response.
      * wfird: possible to get the filter phase response.

      * Initial release.
