I have released a new version of Seed7: seed7_05_20110522.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).

- FAQ answers, explaining that Seed7 is not a descendant of Pascal
    and how Seed7 uses abstract data types, were added.
- Documentation comments were added or improved in the files
    "bigfile.s7i", "bigint.s7i", "bigrat.s7i", "binary.s7i", "cgi.s7i",
    "charsets.s7i", "complex.s7i", "encoding.s7i", "float.s7i",
    "getf.s7i", "gzip.s7i", "inifile.s7i", "keybd.s7i", "rational.s7i",
    "shell.s7i", "socket.s7i", "strifile.s7i", "stritext.s7i",
    "time.s7i", "utf16.s7i", "utf8.s7i", "fil_rtl.c" and "ut8_rtl.c".
- The new libraries "color.s7i", "enable_io.s7i",
    "external_file.s7i", "file.s7i", "null_file.s7i", "osfiles.s7i",
    "stdio.s7i", and "text.s7i" were added. The contents of this
    libraries were extracted from the "seed7_05.s7i" library. Programs,
    which need functionality from "text.s7i", "osfiles.s7i" or
    "color.s7i", must now include them.
- To keep basic compatibility, the "stdio.s7i" library is included
    from "seed7_05.s7i", but in a future version this may change. To
    cope with this change programs, which use standard I/O, should
    include "stdio.s7i".
- The interpreter and the runtime library were improved to support
    forward declarations of variables (the action DCL_FWDVAR is used
    for this purpose).
- All usages of the function 'fileExists' and its definition in the
    "seed7_05.s7i" library, were removed. The functions 'fileType' and
    'fileOpenSucceeds' can be used as replacement.
- Checks for 'sqrt' were added to the "chkbig.sd7" program.
- The bigInteger 'sqrt' function was improved, to return 0_ for
    sqrt(0_) instead of raising an exception.
- The logic of 'null_file' and 'socket' was changed, such that the
    functions 'length', 'seek' and 'tell' raise FILE_ERROR (This files
    are not seekable).
- The function 'replaceHexChars' in "cgi.s7i" was renamed to
- The function 'removeUtf16SurrogatePairs' in "charsets.s7i" was
    renamed to 'replaceUtf16SurrogatePairs'.
- The new function 'openSocket' was introduced in "socket.s7i".
- Unnecessary definitions were removed from "graph.s7i".
