News

New in Version 0.2 
================== 
 
* 16 bit support using 32-bit addressing syntax 
 
* New form: Local labels support/declarations 
  (locals (<label-name> ...) <item> ...) 
 
* Syntax change: all label definitions are now written 
  (label <name> <item> ...) 
 
* Syntax change: For consistency, the "direcs" directive has been 
  replaced by "begin". "begin" is now usable in data and heap 
  directives. 
 
* Support for Guile 1.8 
 
* Support for Scheme48 module interfaces 
 
* sassy-mode minor Emacs mode (sassy.el) 
 
* Segment Override prefixes and branch hinting prefixes 
 
* Better handling of default operand sizes, optimizing generated code 
  sequences for size. 
 
* New version of sassy-make-bin (includes a data section now) 
 
* Fixes for with-win with-lose with-win-lose, so that writing assembly 
  in a, umm, "natural" cps style is possible. 
 
* Numerous bug fixes, clean-ups, and more error checks. 
  See files ChangeLog and CHANGES-old for details.
