I have released a new version of Seed7: seed7_05_20150823.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 example program raytrace.sd7 has been added. This program is a
    raytracing demo.
- The library vector3d.s7i, which supports 3D vectors, has been
- The compiler s7c has been improved to create code to manage free
    lists for struct data. This avoids many calls of malloc() and
    free(). The maximum length of the free lists is determined
    automatically at run-time.
- In color.s7i the elements of the type color have been renamed to
    redLight, greenLight and blueLight. The files mahjong.sd7 and
    draw.s7i have been changed to use the new element names of the
    type color.
- The functions doubleToCharBuffer, fltDgts and fltSci in flt_rtl.c
    have been improved to work without calls of strlen().
- The function bigHexCStri in big_rtl.c has been improved to use
    fewer calls of memmove() and strlen().
- The function process_pragma() in analyze.c has been improved to
    use fewer calls of strlen().
- The function opendir in dir_dos.c and dir_win.c has been improved
    to work without calls of strcat().
- The functions striAsUnquotedCStri and bstriAsUnquotedCStri in
    striutl.c have been improved to use fewer calls of strlen().
- The function cp_to_command in striutl.c has been improved to use
    fewer calls of os_stri_strlen.
- The function getcaps in trm_cap.c has been improved to use fewer
    calls of strcat().
- The function fix_capability in trm_inf.c has been improved to use
    fewer calls of strcat().
- The function strLit in str_rtl.c has been improved to work
    without calls of strlen().
- The functions calculate_output_length and print_stri in error.c
    have been improved to use fewer calls of strlen().
- The function prot_os_stri has been removed from traceutl.c.
- The macros 'likely' and 'unlikely' have been added to functions in
    act_comp.c, analyze.c, arr_rtl.c, big_gmp.c, big_rtl.c, chr_rtl.c,
    cmd_rtl.c, cmd_unx.c, cmd_win.c, con_win.c, hshlib.c, hsh_rtl.c,
    soc_rtl.c, striutl.c and traceutl.c.
- Checks for err_info != OKAY_NO_ERROR have been replaced by checks
    for pointer variables beeing NULL in cmd_win.c, dir_rtl.c,
    fil_rtl.c, pcs_unx.c, pcs_win.c, striutl.c. Since references to
    err_info are used this variable cannot be placed into a register.
    The pointer variables used now can be placed into a register.
- Variables in big_rtl.c, dir_rtl.c and striutl.c have been changed
    to constants.
