I have released a new version of Seed7: seed7_05_20150201.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 option -p of the interpreter (Specify a protocol file, for
    trace output) has been documented in FAQ, s7.1 and in the help
    function of the interpreter.
- The behavior of a Seed7 program, when it receives a signal, has
    changed. Now a program is terminated, when it receives a signal.
    The old behavior, that asks for RETURN or '*', is used when
    interpreter or compiler are called with the option -ts.
- The option -ts of interpreter and compiler (Trace signals) has
    been documented in FAQ, s7.1, s7c.1 and in the help functions of
    the programs.
- Documentation comments in integer.s7i, bigint.s7i and char.s7i have
    been improved.
- The function bitsetElemAsHex (in comp/set_act.s7i) has been
    improved by a factor of 7 (measured with gcc and Valgrind).
- The operator sci has been improved in integer.s7i and bigint.s7i.
- The function check_sci, which checks the sci operator has been
    added to chkint.sd7.
- The function check_str, which checks the str function has been
    added to chkset.sd7.
- The function doRemoveCmd in cli_cmds.s7i has been improved to write
    a message when the operation is not permitted.
- The compiler has been improved to generate better code for the
    action STR_MULT.
- The function check_string_mult, which checks string
    multiplications, has been added to chkstr.sd7.
- The function bitsetNonZero has been added to set_rtl.c. This
    function uses loop unrolling inspired by Duff's device.
- The function setNext (in set_rtl.c) has been changed to call
    bitsetNonZero. This improves the speed of setNext by a factor of 2
    (measured with gcc and Valgrind).
- The function strMult in str_rtl.c has been improved to use a binary
    method for string multiplication. This improves the speed of
    setMult by a factor of 2 (measured with gcc and Valgrind).
- The function drwEmpty has been added to drw_x11.c drw_win.c and
