Here's the NEWS:

Changes in Version 0.1.3
	
	* initial support for SGI hardware
	 
        * -Wall used for compilation: no warnings except for some flex
	  related stuff that is hard to correct, and an unsigned/signed
	  comparison that cannot be avoided in libsoundfile/soundfile.cc.

	* many opcodes ported from Csound (butterworth filters, flanger,
	  ugens3)

	* new envelope opcode added, but not tested. does complex, trigger
	  related enveloping from a function table, with multiple stages
	  and complete arbitrariness.

	* new flanger module (it sounds *cool*; hook up the delay
          input to the LFO)

	* LFO module now has output amplitude of 0-1, making it more
	  useful for control purposes.

	* function table code cleaned up and somewhat rationalized

	* new make.config file, to support platform-specific build
          issues
	  
        * audio hardware related files now in separate library, to
	  make multi-platform stuff easier and cleaner. config.h contains
	  definitions to control which audio HW interfaces are usable,
	  since you can use more than one (eg OSS and ALSA at the same
	  time).

	* new Platform() object to support platform-specific issues.

	* GtkCurve modified to support envelope setting (not complete)

	* many, many bug fixes
