+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
