+v0.1a - initial release (7 Nov 1998)
+
+v0.1b - released 1 Oct 99
+ - filter subband and window subband from Lame3.x added
+ - cleaned up some memory stuff in psy.c
+ - a fast mode switch (-f) which turns off psychoacoustics
+ -instead of having the psymodel calculate SNR
+ just use a bunch of preset values. I just made up
+ some SNR values based upon my test file. These
+ could probably be tuned so that there's a set of SNR
+ values for rock, pop, classical, voice etc.
+
+v0.1d - released 14 Oct 99
+ - cleaned up some code
+ - removed decoding source code (use mpg123 instead :)
+ - renamed subs.c to fft.c (which is mostly what it does :)
+ - moved the filter/window_subband into subband.c
+ - split encode.c into generic code (encode), LayerI code (encodeI)
+ and layerII code (encodeII)
+ - no longer use obtain_parameters(). interactive input is a pain
+
+v0.1e - released 15 Oct 99
+ - cleaned up some code
+ - defaults to 192kbps, psy model 1 with extension mp2 (see encoder.h)
+ - added (-a) downmix to mono option (code in encode.c/get_audio() )
+ - transplanted FHT-based fft() from LAME.
+ - II_f_f_t() now calls fht(). heaps faster. (in tonal.c used by psymodel 1)
+ This could be neater though.
+ - PDS's II_scale_factor_calc() put in encodeII.c
+
+v0.1f - released 16 Oct 99
+ - PDS's updated scale_factor_calc
+ - integrated a few functions in tonal.c/II_psycho_one() which gave about a 15%
+ speedup when using psymodel 1
+
+v0.1g - released
+ - tweaked tonal.c/threshold() 10-15% improvement in this routine.
+
+v0.2a - released 24 october 1999
+ - changed base source code from mpegaudio.tar to the dist10/lsf/encoder. This new code includes lower sampling frequency (LSF) extensions.
+ - added in most of the changes already done.
+ - LSF mode is faulty. Seg faults after about 190 frames here. LSF mode works if you turn off psy models though (-f)
+
+v0.2b - released 30 October 1999
+ - added a "-q n" mode. will only calculate the psy model every n frames.
+ "-q 0" is equivalent to "-f".
+ - reimplemented "downmix to mono" -a switch
+ - WAV file support from Nick Burch <gagravarr@SoftHome.net>
+ - some code cleanup - removed more LayerI & III stuff.
+
+v0.2c - skipped this release
+
+v0.2d - released 6 November 1999
+ - used Mathew Hendry's enhanced fht() with table lookup (20% faster)
+ - made add_db an inline function and tweaked it (25% faster)
+ - code cleanup - renamed psy.c->psycho_II.c, tonal.c->psycho_I.c, other misc stuff
+ - added a "no padding" (-r) switch. Needed by the rfa.org (thanks to Federico Grau)
+ - tweaked threshold 33% speedup.
+
+v0.2e - released 14 December 1999
+ - Some minor speedups from PDS in encode.c
+ - Changed // comments to /* */ style
+ - Merged some functions in subband.c
+ - Cleaned up file input parsing a little.
+ - Now reads PCM from /dev/stdin if this is specified as input filename (kludgy but works for me)
+ - Started putting tables into exe. (only enwindow done so far)
+
+v0.2f - released 15 April 2000
+ - mainly cosmetic changes in the source and code layout
+ - removed a lot of unused functions, and split common.c into more logical subumits.
+ - about 15-20% faster when using psymodel I. (merged some functions in psycho_i.c)
+
+v0.2g - released 22 April 2000
+ - added a VBR mode. See README.VBR
+ - cleaned up more code.
+
+v0.2h - stdio/stdout now parse a little better using '-'
+ - tables now included in the exe thanks to Oliver Lietz <lietz@nanocosmos.de>
+ (I haven't had a chance to test it much though)
+ - including the tables in the exe seems to have boosted speed quite a bit (25%?)
+ - re-implemented byte-swapping in get_audio.c (command line switch -x )
+
+v0.2i - Released 13 July 2001
+ - DAB extensions from Phillipe Jouguet <philippe.jouguet@vdldiffusion.com>
+ - Added a switch to swap the input channels (can someone confirm that toolame
+ swaps them incorrectly by default)
+
+v0.2j - Released 13 February 2003
+ - Definitely LGPL
+ - VBR mode is stable for all sampling frequencies. (See README.VBR for details)
+ - speedups and cleanups from
+ Phillipe Jouguet - philippe.jouguet at vdl.fr
+ (spelling, LSF using psyII, WAVE reading)
+ Henrik Herranen - leopold at vlsi.fi
+ (WAVE reading)
+ Andreas Neukoetter - anti at webhome.de
+ (verbosity patch '-t' switch for transcode plugin)
+ Sami Sallinen - sami.sallinen at g-cluster.com
+ filter_subband loop unroll
+ psycho_i fix for "% 1408" calcs)
+
+v0.2k - Released 16 February 2003
+ - Nicolas Croiset
+ unlimited file read size for stdin
+ fixed bitstream ending so that mp2 files can be concatenated
+ DAB options now comes with a size argument
+ (finally?) fixed the core dump in psycho_1
+ - Ricardo Schelp ricardoschelp at arnet.com.ar
+ combined window/filter subband routine. nice speed increase.
+
+v0.2l - Released 3 March 2003
+ - Added new psychomodels
+ -1 use precomputed values
+ 0 very low complexity
+ 1 same old psy model 1
+ 2 same old psy model 2
+ 3 psy model 1 rewritten from scratch
+ 4 rewritten psy model 2
+ - Rewrote the bitstream encoding routines
+ - Sped up the sin/cos/atan stuff in psymodel 4 (using tables now)
+
+v0.2l with ZMQ output - February 2014
+ - added outputzmq.{h, c}
+ Matthias P. Braendli
+ - integrate into FDK-AAC-DABplus in February 2016
