+## [1.3] - 1998-03-18
+- Added intrinsic transcendental functions for constant literal
+ expressions (pi, sin, cos, tan atan, asin, acos, exp, ln, log, pow)
+- Added warnings for control register load/use hazards
+- More sophisticated constant expression evaluation including
+ implicit float/integer conversion. Results of expressions are
+ typed and so formatted in the listing and symbol table.
+- Various fixes including stray pointers, etc. (Thanks to Dirk Farin
+ farindk@trick.informatik.uni-stuttgart.de)

+## [1.2] - 1994-05-02
+Andreas Gustafsson <gson@joker.cs.hut.fi>
+- Added DS and DSM directives
+- Generalization of the use of "*" allowing current program counter
+ to be used in any expression (including "org l:*" which is useful
+ for changing spaces without changing the PC)
+- Noted a bug with MOVEP to a non-symbolic I/O address. I believe
+ this is now fixed.
+- Noted that mispelled argumentless operators will be treated as
+ labels. For example, N0P (N-zero-P) will be treated as a label.
+ Unfortunately, my own use of a56 (i.e. using cpp as the macro
+ pre-processor) complicates this. However, the grammar might have
+ been simpler if the lexical analyzer was able to distinguish
+ between label declarations and references instead of leaving that
+ up to the YACC parser.
+
+Tim Channon <tchannon@black.demon.co.uk> and Peter Breuer
+<ptb@comlab.ox.ac.uk>
+- Missing ";" in grammar!
+
+Rober Ganter <ganter@ifi.unibas.ch>
+- Fixed bad comment on line 10 of a56.y
+
+Quinn C. Jensen <jensenq@zdomain.com>
+- Listing now includes psect usage summary
+- Better checking of movec arguments
+- Added int(value) function to convert floating point constant
+ expression to integer (by truncation)
+- Correctly convert a floating -1.0 to 0x800000
+- Wrote a new lexical analyzer and lexical parser generator
+- Many other minor enhancements and fixes.
+- Ported to DOS using DJ Delories' GCC port. (Tools available
+ at ftp://omnigate.clarkson.edu/pub/msdos/djgpp)
+
+## [1.1] - 1992-08-06
+- Jcc, JScc, Tcc recognizes "CC" synonym for "HS" (Tom)
+- LUA syntax fixed (Tom, Stephen)
+- DIV syntax fixed (Tom)
+- XY move fixed (Tom, Stephen)
+- a56 now detects phase errors (changes in symbol values
+ between pass 1 and 2)
+- several causes of phase errors fixed
+- immediate value handling improved for both integer and
+ fixed-point values
+- symbols have type (INT or FLOAT)
+- cpp droppings are properly handled
+- ALIGN pseudo-op added
+- Many thanks to Tom Cunningham at Motorola who noted several bugs,
+ fixing most of them. Thanks also to Stephen Edwards at CalTech for
+ his fixes as well. Both he and Tom fixed up the XY parallel move
+ code; I believe all the fixes are integrated.

+## [1.0] - 1991-11-28
