Changes:
- The library vecfont10.s7i, which defines the standard vector font
with capital height 10, was added. Now mahjong.sd7 and shisen.sd7
use vecfont10.s7i.
- The programs mahjong.sd7, pairs.sd7, shisen.sd7 and sokoban.sd7
were improved to fit into a screen with a resolution of 1024 x 768.
- The library make.s7i was improved: The parsing of command
parameters (used by the Unix version of the echo command), was
improved. The processing of pattern rules was improved (The rule
with the shortest stem value is used, when several rules match).
- Functions to read a makefile were moved from make.s7i to the new
library makedata.s7i.
- The reading of makefiles was improved: The processing of the gmake
directives 'ifeq' and 'ifneq' was improved to allow else clauses.
The processing of the nmake directive 'if' was added. Merging of
dependencies for rules with the same target was improved.
- The parse function for time values (library time.s7i) was improved
to allow fractions of a second.
- The functions getSubNodes and getContent and a for-loop for xmlNode
values were defined in the library xmldom.s7i.
- The compiler was improved to initialize bstring literals correctly,
when pointers are 64-bit and integers are 32-bit.
- The font libraries cronos16.s7i, cronos27.s7i, modern27.s7i and
vecfont18.s7i were improved to include vectorfont.s7i.
- The font libraries stdfont10.s7i, stdfont12.s7i, stdfont14.s7i,
stdfont16.s7i, stdfont18.s7i, stdfont20.s7i and stdfont24.s7i were
improved to include bitmapfont.s7i.
- The program dnafight.sd7 was improved to limit the speed of the
animation.
- The program make7.sd7 was improved to recognize the options
correctly. Additionally make7 inherits also all improvements of
makedata.s7i and make.s7i.
- The program ftp7.sd7 was improved to accept the option -?.
- The graphic libraries drw_x11.c and drw_win.c were improved to draw
the background of maximized windows with the color of the last
clear command.
Feature safe: yes
Changes:
20121007:
- An error message, that could occur when the Seed7 interpreter is
compiled, is explained in the FAQ and to 'src/read_me.txt'.
- A description of the for-step-statement was added to the manual.
- The library make.s7i was improved. Now makefile dependencies can
contain colons (:) and equal signs (=). The parameters of the echo
command are parsed better now. Calls of the function callOwnProgram
are also avoided now. This way the library works correctly, when it
is used by programs other than make7.sd7.
- The library tar.s7i was improved to set the file mode, when an
archive is extracted.
- Testcases for a variant of the @:= operator, which copies a string
to another, were added to the program chkstr.sd7.
- Interpreter and compiler were improved to support the situation,
when source and destination of the @:= operator (action STR_POSCPY)
are identical.
- The compiler was improved to support the action ITF_DESTR.
- The compiler was improved, to call C compiler and linker with
specific options, such that unneeded functions are ommited (when
the linker and executable file format support this feature).
- The compiler was improved to remove debug symbols, unless called
with -g (some makefiles now define LINKER_OPT_NO_DEBUG_INFO).
- The function name(PROGRAM) was improved, to return the program name
without following symbolic links.
- The function path(PROGRAM) was improved, to follow symbolic links
(see function followLink in cmd_rtl.c). Consequently dir(PROGRAM)
also follows symbolic links.
- The function CommandLineToArgvW in cmd_win.c was improved.
- The files itf_rtl.c and itf_rtl.h, which contain interface
functions, were added.
- The makefile mk_mingc.mak was added to support compilation of the
self extracting version of Seed7.
20120923:
- Experimental support for automatic memory management with reference
counting was added to the interpreter.
- The libraries external_file.s7i, field.s7i, stritext.s7i, gzip.s7i,
listener.s7i, pixmap_file.s7i, shell.s7i, socket.s7i, strifile.s7i,
dir.s7i, utf16.s7i, utf8.s7i and xmldom.s7i were improved to use
the function toInterface.
- The function name(PROGRAM) was improved, to return the name of the
program without extension and without path.
- The interpreter was improved to support the action ITF_DESTR.
Feature safe: yes

cmd_environment() and cmd_getSearchPath().
- In cmd_rtl.c the functions add_stri_to_array() and
complete_stri_array() were introduced and used in read_dir(),
getSearchPath() and cmdEnvironment().

to fit to the names used in graph.s7i.
- Parameter names in clib_file.s7i, keybd.s7i, sockbase.s7i,
socket.s7i, utf8.s7i, fil_rtl.c, gkb_rtl.c, kbd_rtl.c, soc_dos.c,
soc_rtl.c and ut8_rtl.c were changed to fit to each other.
- The function conv_from_os_stri() was added to striutl.c .
- The function concat_path in str_rtl.c was improved to work
correctly, when the relative path contains "..".

improved.
