I have released a new version of Seed7: seed7_05_20070305.tgz

In the Seed7 programming language new statements and operators
can be declared easily. Types are first class objects and therefore
templates/generics need no special syntax. Object orientation is
used when it brings advantages and not in places when other
solutions are more obvious.

Seed7 is covered by the GPL (and LGPL for the Seed7 runtime library).

- The support for float was changed to use IEEE 754 NaN and Infinity
    instead of exceptions.
- The exception checking program chkexc.sd7 was improved and the
    chkflt.sd7 program was added.
- All exponentiation operators were improved to evaluate 0 ** 0 to 1.
- The associativity of the ** operator was changed to work right to
- A declaration for an = and <> operator was added for interface
- Basic support for exceptions in compiled programs was added.
- Parts of the manual describing float operations and exponentiation
    were improved.
- The performance of the flt_ipow action was improved.
- The compiler was improved to produce better code for the primitive
    actions arr_sort, arr_times, cls_eq, cls_ne, flt_isnan, flt_log10,
    int_fact, rfl_append, rfl_cpy, rfl_for, rfl_mklist, rfl_ne, rfl_tail
    and str_str.
