Version 2.20 - October 8, 1994
------------------------------

This release fixes a bug in the lexer used by AKA, to do with
recognition of number literals in scientific notation. Previous
versions would treat as an identifier the 'e' embedded in, for
example:

  -1.3e-10

The resulting .OPP file would then fail to translate, requiring
manual amendment.

Version 2.21 - October 10, 1994
-------------------------------

Bug fixed whereby the long keywords CREATESPRITE, APPENDSPRITE
and CHANGESPRITE were being truncated in the .OPP file by AKA,
requiring manual amendment.

Version 2.30 - January 12, 1995
-------------------------------

The size of the symbol table is increased from 1024 to 1536
entries.
