I have released a new version of Seed7: seed7_05_20140907.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 function setSearchPath has been added to the library
- The compiler has been improved to write an error message, when the
    sets of a case-statement overlap. Until now this situation was only
    recognized by the C compiler.
- The interpreter has been improved to raise an exception, when the
    current value of a case-statement is element of two sets.
- There have been changes in the libraries makedata.s7i and make.s7i.
- The macro expansion in makedata.s7i has been changed. Now all macro
    expansions (except the expansions of internal macros) are done with
    the function applyMacros.
- In makedata.s7i the function applyMacros has been improved to
    process the makefile macro functions wildcard, error and warning.
- The functions evalFunction and getMacro, that where used to do
    macro expansion when the makefile is read, have been removed.
- The code to read the definition of recursively expanded variables
    has been changed to do no macro expansion. This macros are expanded
    when they are used.
- The library make.s7i has been improved to read the parameters
    for the commands rm, cp, and mv as Unix shell parameters (with the
    function getUnixCommandParameter).
- The library make.s7i has been improved to read the parameters
    for the commands del, copy, xcopy and move as Dos/Windows batch
    parameters (with the function getDosCommandParameter).
- Interpreter and compiler have been improved to support the action
- The batch file bin/call_gcc.bat has been changed to work correctly,
    when it is called from any directory.
- Writing error messages in error.c has been changed to use prot_...
    functions instead of printf.
