This is a bug-fix release with related upgrading of functionality. The most useful improvements are:-
The long-standing laxity of integer-type recognition is addressed. Coan now correctly construes and calculates with values
of all the C integral types from char through unsigned long long. The integer promotions and the usual arithmetic conversions are applied.
Character constants are handled by integer parsing for the first time. Multi-byte utf8 character constants and character constants
expressed as escaped hex or octal codes, as well as ascii characters, are correctly evaluated.
A complete listing of the changes can be found in the Changelog at http://coan2.sourceforge.net/
