Changes:
* The function setSearchPath has been added to the library
process.s7i.
* 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
CMD_SET_SEARCH_PATH.
* 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.

Changelog:
* The chapter about files in the manual has been improved.
* Variants of the for-each-loop with an until condition have been
added to array.s7i.
* The parse operator for characters has been improved to accept only
strings with a length of 1.
* The function trimValue has been introduced. This function trims a
string such that it can be converted to a specified type.
* The exception handlers for RANGE_ERROR have been removed from the
functions read and readln in enable_input.s7i. The functions read
and readln now raise range RANGE_ERROR when the conversion to the
target type fails.
* Occurances of io_ok, io_error, io_empty and io_filled have been
removed from the libraries. This undocumented feature was not used
for years. The function succeeds and the functions read and readln
with default value are better suited for error checking, when data
is read.
* The exception handlers in interpreter and compiler have been
improved to allow an otherwise part.
* The function succeeds has been introduced. This function executes
a statement and returns TRUE when no exception occurs.
* The example programs nicoma.sd7 and savehd7.sd7 have been improved
to use the new function succeeds.
* The parse operator for float has been changed to raise RANGE_ERROR
when leading whitespace is found.
* The library make.s7i has been improved to accept the commands
erase, xcopy, mv, move and rem.
* The library makedata.s7i has been improved to accept the macro
functions subst and patsubst.
* The reading of rules in makedata.s7i has been improved to read
commands without macro substitution. The macros in commands are
substituted just before the commands are executed.
* The make functions in make.s7i have been changed to raise
FILE_ERROR when a command fails.
* The function applyMacros in makedata.s7i has been improved to
accept macro functions and the shorthands of patsubst.
* The function replaceSuffixes in makedata.s7i has been improved to
accept pattern substitution with the % character.
* In the library make.s7i the logging has been removed from the
functions doRm, doCp, doPwd, doEcho, doCd, doMake, doOneCommand,
doCommands and processCommand.
* The program chkflt.sd7 has been adjusted to work with the strict
parse operator for float.
* Interpreter and compiler have been improved to support the actions
PRC_BLOCK_CATCH_ALL and PRC_BLOCK_OTHERWISE.
* The program sudo.c has been improved to work without upper limit
for the parameter length.
* The functions checkIfOutsideRange and negate have been added to
int_act.s7i.

Changes:
* The handling of ctrl-c has been changed to work better under
windows.
* The runtime of the function intPowOvfChk in int_rtl.c has been
reduced to 57% (measured with gcc and valgrind).
* The generation of code in the compiler for the action INT_POW has
been improved. When the base is a negative power of two the
exponentiation is done with a shift instead of a call of intPow
(respectively intPowOvfChk).
* The overflow checking for INT_POW in the compiler has been
improved. When base or exponent is known the overflow checking is
done with inline code and intPow is called instead of intPowOvfChk.
* Documentation comments have been added to bitsetof.s7i
* Tests for ** have been added to chkint.sd7 and chkovf.st7
* The tests for * and *:= in chkovf.st7 have been reorganized.
* An interrupt_flag has been introduced in the interpreter. This flag
is used for exception handling and for signal handling. Exceptions
set interrupt_flag and fail_flag (with the macro set_fail_flag).
Signals set only the interrupt_flag (file sigutl.c). The
interrupt_flag is handled in exec_action (file exec.c).
* The functions signal_name, handle_signals, handle_segv_signal,
handle_term_signal and activate_signal_handlers in sigutl.c have
been improved.
* The functions continue_question, write_curr_position and
show_signal in runerr.c have been improved.
* The functions handle_int_signal, readChar, doGetcFromTerminal,
doGetsFromTerminal, doLineRead, doLineReadFromTerminal, doWordRead,
doWordReadFromTerminal, filGetcChkCtrlC, filGetsChkCtrlC,
filHasNextChkCtrlC, filLineReadChkCtrlC and filWordReadChkCtrlC
have been added to fil_rtl.c. This functions support reading from
a terminal with a check for ctrl*c. This functions are used by the
interpreter (file intlib.c).
* Tracing has been added to functions in int_rtl.c.
* Configuration defines for CTRL_C_SENDS_EOF,
SIGNAL_HANDLER_CAN_DO_IO and INT64TYPE_NO_SUFFIX_BUT_CAST have been
added to makefiles.

Changes:
* The compiler has been improved to generate overflow checking code
by default. The generation of overflow checking code can be
switched off with the option -so.
* The exception OVERFLOW_ERROR has been introduced. It is raised by
the interpreter and by compiled programs when an integer overflow
occurs.
* A paragraph about integer overflow and the installation of Seed7
has been added to the FAQ.
* The chapter about exceptions in the manual has been improved.
* The program chkovf.sd7, which checks the recogition of integer
overflows, has been added.
* Checks for +, -, *, rem, mod, <<, +:=, -:=, *:=, succ, pred, incr
and decr have been added to chkint.sd7.
* Checks for the lpad operator have been added to chkstr.sd7.
* The compiler option -r has been replace by the option -sr.
* The program calc7.sd7 has been improved to report MEMORY_ERROR and
OVERFLOW_ERROR.
* The library make.s7i has been improved such that make7.sd7 accepts
echo (and echo.) statements without parameters.
* The function eof has been defined for the type tlsFile in tls.s7i.
* The function gets in tls.s7i has been improved.
* The function getHttp in gethttp.s7i has been improved to avoid an
endless loop when eof has been reached.
* The function memcpy_from_strelem has been added to striutl.c. This
function uses loop unrolling inspired by Duff's device and a trick
with a binary or (|=) to check for allowed values.
* The functions filWrite, socWrite and bstParse have been changed
to use memcpy_from_strelem. The reduction in runtime has been
measured with gcc and valgrind. The runtime of filWrite, socWrite
and bstParse has been reduced to 53%, 61% and 56% respectively.
* Documentation comments have been added to integer.s7i, bin32.s7i,
intlib.c and striutl.c.
* The compiler has been improved to generate overflow checking code
for *, <<, >>, *:=, <<:= and >>:= .
* The generation of overflow checking code for the operators rem and
mod has been improved.
* Checks for overflow, division by zero, numeric error and index out
of bounds in compiled programs now use the macros ovfChk, divChk,
numChk and idxChk. This macros inform the C compiler about the
unlikeliness of an exception.
* The function fltIPow has been improved to avoid a signed integer
overflow, when the exponent is the most negative integer.
* The primitive actions INT_ULSHIFT and INT_ULSHIFT_ASSIGN have been
added and supported in interpreter and compiler.
* A version of the function uint_rand, which uses 128-bit integers,
has been added to int_rtl.c.
* The function raise_error3 in runerr.c has been renamed to
interprRaiseError.
* The configuration values INT128TYPE, UINT128TYPE and MACRO_DEFS
have been added to cc_conf.s7i. The configuration value
SIGILL_ON_OVERFLOW has been replaced with OVERFLOW_SIGNAL.
* The functions constValueIsEqual, checkRangeFromZero,
process_const_int_lshift, process_const_int_lshift_assign,
process_const_int_rshift_assign, process_const_int_mult,
process_const_int_mult_assign, process_const_int_ulshift_assign,
process_const_int_ulshift and process_const_int_urshift_assign
have been added to int_act.s7i.
* The function intExpr in chkbig.sd7, chkexc.sd7, chkint.sd7 and
chkstr.sd7 has been changed to make sure that the C compiler
cannot evaluate it at compile time.
* The runtime of the functions str_lpad, strLpad and strLpadTemp has
been improved.

Changes:
* The interpreter has been improved to recognize integer overflow.
Now the exception NUMERIC_ERROR is raised, when a program triggers
an integer overflow. The checks for overflow are done in software,
but the overhead is small. With overflow checks the interpreter
needs 0.5% (zero point five percent) more run-time to execute the
program chkint.sd7 (verified with gcc and valgrind).
* A chapter about the Seed7 Structured Syntax Description (S7SSD)
has been added to the manual.
* The for-until-loops in bitset.s7i and bitsetof.s7i have been
improved such that the for-variable has the correct value, when it
is used in the until-condition.
* The function replaceN has been added to string.s7i. This function
does replacements until no occurance of the target string is left.
This function is used by toStdPath to replace multiple occurances
of a character by one occurance (replace("/a///b////c", "//", "/")
returns "/a/b/c").
* The program calc.sd7 has been renamed to calc7.sd7.
* The program calc7.sd7 has been changed to accept the commands
'quit' and 'exit'. This commands can be used to exit the program.
The possibility to leave the program with an empty input line has
been removed.
* The program calc7.sd7 has been improved to write the name of the
exception, when it has been raised.
* The compiler has been improved to allow the generation of overflow
checking code. Overflow checking code can be generated for the
operators +, -, **, +:= and -:= and the functions abs, succ, pred,
incr and decr. Until the rest of the functions is implemented and
enough tests have been added to chkint.sd7 the functionality is
switched off.
* The template FOR_UNTIL_DECLS has been added to forloop.s7i. This
template defines for-loops with a condition.
* The function abs has been moved from the library math.s7i to the
library float.s7i.
* Checks for addition, subtraction, multiplication, power and abs
have been added to chkint.sd7.
* In the compiler the statements to write the C prototypes have been
moved from s7c.sd7 to functions in the files comp/xxx_act.s7i
(xxx is the abbreviation for the corresponding primitive type).
* The functions getReference getParameterAsReference have been added
to comp/expr_util.s7i.
* The function isit_bool from objutl.c has been replaced by the macro
isit_bool (defined in objutl.h). This improves the speed of the
interpreter.
* The function set_card has been improved to call setCard, which
computes the cardinality of a set much quicker.

Changes:
* The makefile mk_freebsd.mk has been changed to work with the new
version of chkccomp.c. Thanks go to Pietro Cerutti for pointing out
the problem.
* The self extracting Seed7 package for windows has been improved to
use gcc version 4.8.1 instead of 4.5.0.
* The new function removeTree, which removes a directory tree, has
been introduced in osfiles.s7i. The function removeAnyFile, which
has been used for the same purpose, is deprecated. Deprecated
functions will be removed in a future version.
* Checks for hash tables with character keys have been added to
chkhsh.sd7.
* The test program "chkcmd.sd7" has been added. This program checks
functions that copy, move and remove files. Note that windows has
race conditions when files are copied, moved and removed quickly in
succession. This bug of windows cannot be fixed in a runtime
library.
* The function temp_name_in_dir has been added to striutl.c.
* The typedef of socketType in common.h has been changed such that
socketType is always int.
* Functions in soc_rtl.c, pol_sel.c and pol_unx.c have been changed
to use the type os_socketType.
* Tracing statements in hsh_rtl.c, cmd_rtl.c, drw_win.c and drw_x11.c
have been changed to use the FMT_ strings from common.h. This way
the tracing is more portable.
* Under Windows the functions cmdRemoveFile and cmdRemoveTree now
rename a file before it is removed. When the renaming fails the
directory is left intact. This avoids half removed directory trees
under Windows, when a process has the current working directory
somewhere in the directory that is to be removed. The renaming also
lowers the probability of race conditions under Windows, but they
still can happen.
* The function checkMoveDirectory has been added to chkccomp.c.
* The target make7 has been added to the makefiles. With 'make make7'
an executable of the make7 program is generated and placed in
seed7/bin.

* The compiler has been refactored. Code has been moved from s7c.sd7
to several compiler libraries. The compiler libraries are licensed
with the GPL and can be found in seed7/lib/comp. The refactored
compiler is the first compiler of the 3.0 series.
* The chapter in the manual about the foreign function interface has
been improved.
* Checks for parse and str have been added to chkflt.sd7 and
chkint.sd7.
* In chkccomp.c code has been moved from main() to the new functions
numericSizes and numericProperties.
* Usages of the macro logError have been added to cmd_rtl.c and
cmd_unx.c.
* The stack size defined in mk_mingc.mak, mk_mingw.mak, mk_msys.mak
and mk_nmake.mak has been changed from 4194304 to 8388608.
* The function cstri_buf_to_stri has been added to striutl.c.
* The generation of float literals in the compiler has been improved
to avoid that precision is lost.
* Interpreter and compiler have been improved to support the actions
BLN_EQ and BLN_NE.

Changes:
* Errors in con_wat.c and drw-dos.c have been fixed (thanks to
"Rugxulo" for the help to fix them).
* The function str in duration.s7i has been improved to work for
negative durations.
* The library tar.s7i has been improved to work with the old file
format that does not use the magic value "ustar".
* The function bigToInt16 has been added to big_rtl.c and big_gmp.c.
* The macros with format strings in common.h have been renamed.
Now the macros have shorter names (starting with FMT_ and F_).
The macros define formats for various integer sizes. This formats
are independend from the actual C compiler and C runtime library.
* The function bigLog10 in big_rtl.c has been improved to work
correctly when BIGDIGIT_SIZE is small.
* The program chkccomp.c has been improved to define
LOCALTIME_WORKS_SIGNED, when localtime can process negative times.
* The program chkccomp.c has been improved to write the define
directives to the file specified with the first parameter.
* The function intParse in int_rtl.c has been improved to accept the
most negative number.
* The function timSetLocalTZ in tim_rtl.c has been changed to avoid
raising an exception when LOCALTIME_WORKS_SIGNED is not defined and
the time is before 1970-01-01. In this case the daylight saving
time flag is set to FALSE.

and bigrat.s7i. It rounds halfway cases away from zero.
* The function str has been improved in the libraries rational.s7i
and bigrat.s7i. Now the function converts to a string with a
decimal representation (e.g.: "1.25"). When repeating decimals are
recognizend they are enclosed in parentheses.
* The operator digits has been improved in the libraries rational.s7i
and bigrat.s7i. Now the operator rounds halfway cases away from
zero.
* Documentation comments have been improved in bigint.s7i, float.s7i,
rational.s7i, bigrat.s7i, char.s7i, big_gmp.c and fltlib.c.

Changes:
* The chapter in the manual about the foreign function interface has
been improved.
* A paragraph about regular expressions and lexical scanner functions
has been added to the FAQ.
* The handling of the actions CHR_CLIT and INT_STRI in the compiler
has been improved. The string buffers for chrCLitToBuffer and
intStrToBuffer use the correct alignment now.
* In big_rtl.c the functions bigParseBasedPow2 and bigParseBased2To36
have been added and bigParseBased has been changed to call them.
This improves the conversion of a string to a bigInteger, when the
base is a power of two. Valgrind measurements of the function
bigParseBased in chkbig.sd7 show a speed improvement with a factor
of 239.
* The macros memcpy_to_strelem and memset_to_strelem (defined in
striutl.h) have been turned into functions (defined in striutl.c).
* The unrolling in memcpy_to_strelem and memset_to_strelem has been
changed from 8 times to 32 times. This improves the performance
for big data amounts by 16% (Measured with valgrind and gcc).
* Usages of the macros memcpy_to_strelem and memset_to_strelem in
bst_rtl.c, fil_rtl.c, soc_rtl.c and str_rtl.c have been turned into
usages of the corresponding functions.
* Calls of cstri_expand, ustri_expand, cstri_expand2 and
ustri_expand2 in analyze.c, chr_rtl.c, flt_rtl.c, infile.c,
str_rtl.c and striutl.c have been turned into calls of
memcpy_to_strelem.
* The functions (macros) cstri_expand, ustri_expand, cstri_expand2
and ustri_expand2 have been removed from striutl.c and striutl.h.
* The functions doCompileAndLink, compileAndLinkWithOptionsOk,
compileAndLinkOk, appendToFile and detemineDatabaseDefines have
been added to chkccomp.c. The function compilationOkay has been
replaced by compileAndLinkOk.

* The chapters in the manual about primitive actions and the foreign
function interface have been improved.
* The names of the C types used in interpreter and runtime library
have been refactored to use camel case.
* The elements in the unions valueUnion (in data.h) and rtlValueUnion
(in data_rtl.h and s7c.sd7) have been refactored to use names with
camel case.
* The library bigint.s7i has been changed to define the operators
radix and RADIX with the actions BIG_radix and BIG_RADIX. This
results in a significant performance improvement when large numbers
are converted.
* Interpreter and compiler have been improved to support the actions
BIG_radix and BIG_RADIX.
* Testcases for the operators radix and RADIX have been added to
chkbig.sd7.
* The compiler has been improved to do an optimization for the action
INT_MDIV when the divisor is known at compile time. When the
dividend is known to be positive or zero it is casted to an
unsigned integer and the quotient is casted back to a signed
integer. Dividing an unsigned integer by a constant is known to be
faster than dividing a signed integer.
* The functions bigRadix, bigRadixPow2, bigRadix2To36 and
uBigDivideByDigit have been added to big_rtl.c
* The function bigRadix has been added to big_gmp.c.
* The functions stri_to_cstri8_buf and cstri8_buf_to_stri have been
added to striutl.c.
* In traceutl.c the function mapTraceFlags has been improved to work
correctly when the parameter trace_level defines several options.
* The function printTraceOptions has been added to traceutl.c.
* In arr_rtl.c the definition of getArgv has been improved to use
less #ifdef directives in the function body.

Changes:
* The documentation file doc/install.txt has been improved to describe
the command 'make install'.
* The chapter about the foreign function interface in the manual has
been improved.
* In striutl.h the macros os_stri_alloc and os_stri_free have been
improved to use a stack like allocation. Allocations done with
os_stri_alloc must be freed with os_stri_free in the reverse order
of their creation. The new macros reduce the runtime of
stri_to_os_stri and cp_to_os_path to 66% of the old time. This
reduces the time used by operating system calls. E.g.: The CPU time
used by the program sydir7 is reduced to 83% of the old time.
* The targets 'install' and 'uninstall' have been added to makefile,
mk_linux.mak, mk_osx.mak, mk_clang.mak, mk_cygw.mak, mk_mingw.mak,
mk_msys.mak, mk_nmake.mak, mk_msvc.mak, mk_bcc32.mak and
mk_bccv5.mak.
* The program setwpath.c has been added. This program sets the search
path (PATH variable) under Windows.
* The obsolete target 'hi' has been removed from the makefiles.
* The functions initEmulatedCwd, cmdSetenv (both in cmd_rtl.c),
setEmulatedCwd (in striutl.c) and freeArgVector (in cmd_unx.c) have
been adjusted to work with the stack like allocation of
os_stri_alloc and os_stri_free.
* The functions heapAllocOsStri and heapFreeOsStri have been added to
striutl.c.
* Usages of MAX_SYMLINK_PATH_LENGTH in cmd_rtl.c have been replaced
with MAX_OS_STRI_LEN.

Changes:
* The function setSockOpt and the constant SO_REUSEADDR have been
added to sockbase.s7i. Many thanks go to Domingo Alvarez Duarte
for pointing out that this functionality was missing.
* The function openInetListener in listener.s7i has been improved
to succeed when the socket is reused (it calls setSockOpt with
SO_REUSEADDR now).
* The functions opendir and wopendir in dir_win.c and the function
opendir in dir_dos.c have been improved to check for the maximum
path length supported by Windows and DOS.
* The functions act_string and act_okay have been removed from
actutl.c.
* The function exec_action in exec.c has been improved to use
get_primact instead of act_okay. This results in a significant
performance improvement in the case when WITH_ACTION_CHECK is
defined and the option -tc is used.
* The function str1Split has been removed from strlib.c.
* Documentation comments have been added to arr_rtl.c, arrutl.c,
cmd_unx.c, cmd_win.c, dir_dos.c, dir_rtl.c, dir_win.c, kbd_inf.c,
kbd_poll.c, scanner.c and ut8_rtl.c.
* Interpreter and compiler have been improved to support the action
SOC_SET_OPT_BOOL.

Changes:
* A new numeric escape sequence for string literals has been
introduced. A backslash followed by an integer literal and a
semicolon is interpreted as character with the specified ordinal
number. E.g.: "abc\128;def". With the old numeric escape sequence
this would be "abc\128\def". Terminating the escape sequence
with ; instead of \ improves the readability, especially when
escape sequences follow each other. Instead of "\8\\12\\7\8\9\\\"
it is now possible to write "\8;\12;\7;8\9;\\" The old escape
sequence is still supported, but it is deprecated and should not
be used. Future versions will warn about the deprecated escape
sequence.
* The conversion functions 'bytes' and 'bytes2Int' in bytedata.s7c
have been improved to support all combinations of signedness and
endianess.
* The functions bStriBe and bStriLe have been removed from
bstring.s7i. The function 'bytes' in bytedata.s7c can be used as
replacement.
* Checks for lowestSetBit and UNSIGNED conversions with the
functions 'bytes' and 'bytes2Int' have been added to chkint.sd7.
* Checks for UNSIGNED conversions with the functions 'bytes' and
'bytes2BigInt' have been added to chkbig.sd7.
* Checks for the function rand have been added to chkset.sd7.
* The parser has been improved to write error messages when the
source file contains unexpected UTF-8 continuation bytes, solitary
UTF-8 start bytes, extended control codes from the C1 set or an
UTF-16 byte order mark.
* In tar.s7i the functions getoct, putspc and putoct have been
improved. The computation of the size of padding data has also
been improved.
* The compiler has been improved to optimize string initialisations
with the function strZero. StrZero creates a string of arbitrary
length with '\0;' (zero) bytes.
* The compiler has been improved to optimize integer exponentiation
(action INT_POW). Now the multiplication pattern is determined at
compile time and the number of multiplications is reduced.
* The performance of the function setCard in set_rtl.c has been
improved by a factor of 2.5.
* The performance of the function setRand in set_rtl.c has been
improved by a factor of 2.3.
* Loop unrolling inspired by Duff's device has been introduced in
striutl.h. The unrolling is used for tight loops which copy byte
data to Seed7 strings in fil_rtl.c, soc_rtl.c and bst_rtl.c. The
performance improvement has been verified with gcc and valgrind.
* The example program err.sd7, which checks compile time error
messages, has been improved.
* The old way to store the data of constant bigIntegers has been
removed from compiler and runtime library.
* The buffers used in intRadix and intRadixPow2 (file int_rtl.c) have
been enlarged to fit for the most negative number with a base of 2.
* In itflib.c the functions itf_cpy and itf_cpy2 have been fixed to
work correctly, when the destination is converted from a struct to
an interface.
* In traceutl.c the tracing of characters has been improved in the
functions prot_char, prot_os_stri, prot_stri_unquoted and
prot_bstri.
* In ut8_rtl.c the function ut8Getc has been improved to use smarter
checks for ranges of characters.
* The deprecated variant of the function str, which has a second
parameter to specify a numeric base, has been removed. The
operators radix and RADIX can be used instead.
* Interpreter and compiler have been improved to support the new
actions INT_BYTES_BE, INT_BYTES_LE, INT_BYTES_BE_2_INT and
INT_BYTES_LE_2_INT. The functions intBytesBe, int_bytesBe,
intBytesLe, int_bytesLe, intBytesBe2Int, int_bytesBe2Int,
intBytesLe2Int and int_bytesLe2Int have been added.
* Support for the actions BIG_CLIT, INT_TO_BSTRI_BE, INT_TO_BSTRI_LE,
INT_BYTES_BE_2_UINT and INT_BYTES_LE_2_UINT has been removed from
interpreter and compiler. The functions bigImport, bigCLit,
big_clit, intToBStriBe, int_toBStriBe, intToBStriLe, int_toBStriLe,
intBytesBe2UInt, int_bytes_be_2_uint, intBytesLe2UInt and
int_bytes_le_2_uint have been removed.

Changes:
* The manual chapter describing the foreign function interface has
been improved.
* The handling of Unicode in the console has been improved. Cursor
positioning and writing Unicode strings to the desired position
works now also under Linux.
* A strict checking of all strings, that are passed to C functions,
has been introduced. Zero bytes and non Unicode characters in the
original string raise the exception RANGE_ERROR now.
* The performance of several loops in the runtime library has been
improved. Now the loops use indices instead of pointer increments
and they work downward towards an index of zero. This allows C
compilers to do more optimizations (verified with gcc and
valgrind).
* The enumeration types signedness and endianess have been added to
bytedata.s7c.
* The conversion functions bytes, bytes2Int and bytes2BigInt have
been added to bytedata.s7c. The new function allow conversions
to and from signed and unsigned byte strings with big- and
little-endian byte order. This functions replace the less flexible
functions bytesLe2Int, bytesBe2Int, bytesLe and bytesBe.
* The functions bStriBe, bStriLe, bStriBe2BigInt and bStriLe2BigInt
have been moved from bytedata.s7c to bstring.s7i.
* The performance of the functions int16AsTwoBytesLe,
int32AsFourBytesLe, int64AsEightBytesLe int16AsTwoBytesBe,
int32AsFourBytesBe and int64AsEightBytesBe has been improved.
* Documentation comments have been added or improved in cc_conf.s7i,
bytedata.s7i, environment.s7i, sockbase.s7i, actutl.c, big_rtl.c,
big_gmp.c, biglib.c cmd_rtl.c, con_inf.c, con_win.c, con_wat.c,
int_rtl.c, intlib.c, soc_rtl.c, striutl.c and syvarutl.c.
* The program chk_all.sd7 has been improved to check several
compiler options and to allow that the output of interpreted and
compiled compiler differs. The difference of the generated C code
is okay, when the execution of the compiled programs results in
the same output.
* The compiler (s7c) has been improved to do more optimizations for
the action BIG_REM (operator rem).
* The compiler has been improved to count inserted and suppressed
range checks.
* Interpreter, compiler and runtime library have been improved to
allow bstrings with slices. This is used by the compiler to
reduce the memory used for constant bstrings.
* The compiler has been improved to store the data of constant
bigIntegers in bstrings.
* Checks for div, rem, mdiv and mod have been added to chkbig.sd7.
* Checks for float division by zero have been added to chkexc.sd7.
* Checks for float parse have been added to chkflt.sd7.
* In con_inf.c, con_win.c and con_wat.c the function conText has
been replaced by conWrite. ConWrite takes an UTF-32 string and
writes it to the console. If stdout is redirected an UTF-8 string
is written to the destination file.
* The function gen_act_ptr_table has been added to actutl.c. This
function creates act_ptr_table and removes double entries from it.
* The functions intBytesBe2UInt and intBytesLe2UInt have been added
to int_rtl.c.
* Interpreter and compiler have been improved to support the new
actions INT_BYTES_BE_2_UINT and INT_BYTES_LE_2_UINT.
* Checks for the function sigaction() and for integer division and
remainder have been added to chkccomp.c.
* The configuration values ALLOW_BSTRITYPE_SLICES,
CHECK_INT_REM_BY_ZERO and CHECK_INT_REM_ZERO_BY_ZERO have been
added to cc_conf.s7i, chkccomp.c, cmd_rtl.c and s7c.sd7.
* Several versions of timAwait in tim_unx.c have been improved to
restart calls of poll(), ppoll() and select().
* A check for the character '=' in the environment variable name has
been added to the function cmdSetenv (in cmd_rtl.c).
* In striutl.c the functions stri_compress, stri_export_utf8 and
cp_to_cstri8 have been improved and renamed to conv_to_cstri
conv_to_cstri8 and stri_to_cstri8 respectively. Interpreter and
runtime library have been improved to use the new function names.
* The function stri_to_cstri and the macro free_cstri8 have been
added to striutl.c.
* The functions conv_to_cstri, conv_to_cstri8, stri_to_cstri8 and
stri_to_bstri have been improved to use an err_info parameter.

Changes:
* The library tdes.s7i with TDES (Triple DES respectively 3DES)
cipher support has been added.
* The library tls.s7i has been improved to allow encoding with TDES
(3DES) and to accept the handshake message CertificateRequest.
* The function drwGetImage has been added to drw_dos.c (thanks to
"Rugxulo" for pointing out, that it was missing).
* Checks for mdiv and mod have been added to chkbig.sd7.
* The compiler (s7c) has been improved to do more optimizations for
the action BIG_MOD (operator mod). Now the functions bigLowerBits
and bigLowerBitsTemp are used when the divisor is a power of two.
* The compiler has been improved to optimize if-statements, when the
condition is constant.
* The compiler has been improved to optimize the action BIG_MDIV
(operator mdiv) correctly, when the divisor is a negated power of
two (e.g. n div -8). The generated code now corresponds to the
Seed7 expression -dividend >> log(-divisor).
* New functions to open files have been introduced in various
libraries. The new functions are openUtf8, openUtf16, openEcho,
openLine, openTee, openMore, openUpper, openLower, openReverse,
openWindow and openField. The new functions have been added as
replacement for the functions open_utf8, open_utf16, open_echo,
open_line, open_tee, open_more, open_upper, open_lower,
open_reverse, open_window and open_field. The old functions are
still supported, but they are deprecated and should not be used.
Deprecated functions will be removed in a future version.
* The example programs have been changed to use the new functions
to open files.
* Documentation comments have been added or improved in cipher.s7i,
clib_file.s7i, external_file.s7i, shell.s7i, utf8.s7i, utf16.s7i,
unicode.s7i, bytedata.s7i, big_gmp.c, biglib.c, big_rtl.c,
cmdlib.c, cmd_rtl.c, fillib.c, fil_rtl.c, intlib.c, int_rtl.c,
strlib.c, str_rtl.c and entutl.c.
* The functions bigLowerBits and bigLowerBitsTemp have been added
to big_rtl.c and big_gmp.c.
* The free list management in big_rtl.c and big_gmp.c has been
improved to allow the configuration of a maximum free list length.
* The function bigMultAssign1 has been added to big_rtl.c. This
function is used by bigMultAssign when the factor is just one
bigdigit.
* The function bigLog2BaseLShift has been renamed to
bigLog2BaseIPow in big_rtl.c, big_gmp.c and s7c.sd7.
* The function getValue for boolean values has been added to
progs.s7i. Interpreter, compiler and runtime library have been
improved to support it.
* the management of types in the runtime library has been improved.
Now they are attached to the corresponding program. This way they
can be freed by prgDestr().

* The new library unicode.s7i, with functions to convert between
Unicode encodings, has been added.
* The functions utf16beToStri, utf16leToStri, utf7ToStri and
replaceUtf16SurrogatePairs have been improved and moved from
charsets.s7i to unicode.s7i. The functions striToUtf8 and
utf8ToStri have been moved from string.s7i to unicode.s7i. The
functions striToUtf16be and striToUtf16le have been added to
unicode.s7i.
* The actions FLT_MINUS, INT_MINUS and BIG_MINUS have been renamed
to FLT_NEGATE, INT_NEGATE and BIG_NEGATE respectively.

HTTP.
* The operator symbols ~ and ><:= have been added to syntax.s7i.
* Checks for -, mdiv, << and >> have been added to chkbig.sd7.
* The compiler (s7c) has been improved to do more optimizations for
the actions BIG_DIV, BIG_LSHIFT, BIG_RSHIFT, BIG_MDIV, BIG_MULT,
BIG_NEGATE and CHR_CLIT.
* The function charLiteral has been added to the compiler.
* The compiler has been improved to avoid the generation of long
lines for bigInteger literals.
* The function bigMinus has been renamed bigNegate and the function
bigNegateTemp has been added to big_gmp.c and big_rtl.c.

Changes:
* The new library pic_util.s7i has been added. It contains utility
functions for pictures. A picture is a simple way to describe
graphic images as readable text. A picture is an array of strings,
where every character describes the color of a pixel.
* The programs castle.sd7, mahjong.sd7, pairs.sd7, panic.sd7,
shisen.sd7, sokoban.sd7 and sudoku7.sd7 have been adjusted to use
pic_util.s7i.
* The pictures in pic16.s7i and pic32.s7i have been adjusted to be
useable by pic_util.s7i.
* The pictures cancel_pic, folder_pic and reset_pic have been added
to pic16.s7i and pic32.s7i.
* A function to convert a pixmap image to BMP format has been added
to draw.s7i.
* The function getPixelColor has been added to draw.s7i.
* In the example programs all usages of the function clear without
parameters have been replaced with clear(black). The function
clear without parameters is deprecated.
* Interpreter and compiler have been improved to support the actions
DRW_GETIMAGE and DRW_GETIMAGEPIXEL.
* The performance of the function strCLit in str_rtl.c has been
improved by a factor of 10.
* The function init_bstri_constants in s7c.sd7 has been improved to
use the function c_literal instead of cCharLiteral. This way it
cannot happen that a sequence like ??( is interpreted as trigraph
sequence. As a side effect the performance has been improved also.
* The function init_win_constants in s7c.sd7 has been improved to
call getImage instead of getPixel. This improves the performance
dramatically.
* The functions prc_return and prc_return2 in prclib.c have been
improved to avoid using block_body when it is NULL.
* Spelling errors in chlog.txt, faq.htm, faq.txt, install.txt,
manual.htm, manual.txt, problems.txt read_me.txt, src/read_me.txt,
flistutl.c, flistutl.h, heaputl.c, heaputl.h and striutl.c have
been fixed.
* The function drwGetImage has been added to drw_x11.c and
drw_win.c.
* The function drwGetImagePixel has been added to drw_rtl.c.

Changes:
* Compiler and runtime library have been improved to work on Sparc
64-bit machines under OpenBSD. Thanks go to Brian Callahan, for
his support and for providing access to his Sparc 64-bit machine.
* The FAQ explanation concerning portability has been improved.
* The new library cc_conf.s7i has been added. This library manages
configuration values for C compiler and runtime.
* The compiler has been improved to use the library cc_conf.s7i.
* The chapter about the defines used in version.h has been improved
in src/read_me.txt.
* The type rtlGenerictype has been renamed to generictype in the
files of the runtime library. Now compiler and runtime library
both use the name generictype.
* The function checkForLimitedStringLiteralLength, a check for
trigraph sequences and checks for the presence of getrlimit()
and siglongjmp() have been added to chkccomp.c.
* The function setupStack has been added to cmd_rtl.c. This function
tries to raise the stack limit to STACK_SIZE.
* Usages of USE_SIGSETJMP have been renamed to HAS_SIGSETJMP.
* The table key_code has been improved in kbd_inf.c and kbd_poll.c.
Now the erase char of the terminal interface (VERASE) is always
returned as backspace (KEY_BS respectively '\8\'). This improves
the behavior under Cygwin.
* The function utf8_init has been changed in kbd_inf.c and
kbd_poll.c to assume UTF-8 mode when no locale environment
variable is set.
* The function msgDigest in msgdigest.s7i has been changed to use
in-parameters.
* The function configValue has been moved from osfiles.s7i to
cc_conf.s7i.
* The macro REALLOC_STRI_SIZE_SMALLER has been added to heaputl.h.
Several usages of REALLOC_STRI_SIZE_OK in the runtime library have
been changed to usages of REALLOC_STRI_SIZE_SMALLER.
* The compiler has been improved to initialize boolean and
enumeration elements of structs with the values value.boolvalue
respectively value.enumvalue. This is necessary to work correctly
on big-endian systems.
* Interpreter and compiler have been improved to support the actions
ACT_EQ and ACT_NE.

and for providing access to his PowerPC Macintosh under OpenBSD.
* The list of source files and the chapter about the defines used in
version.h have been improved in src/read_me.txt.
* The library tls.s7i has been improved to avoid raising an
exception, when the remote side closes the socket.
* The program chkccomp.c has been improved to write defines for
CHECK_INT_DIV_BY_ZERO, INT_DIV_BY_ZERO_SIGNALS and
DO_SIGFPE_WITH_DIV_BY_ZERO to version.h.

Changes:
20131013:
- Libraries for TLS (Transport Layer Security), SSL (Secure Sockets
Layer) and HTTPS (HyperText Transfer Protocol Secure) support have
been added. The new libraries are: arc4.s7i, asn1.s7i, cipher.s7i,
gethttps.s7i, hmac.s7i, pkcs1.s7i, tls.s7i and x509cert.s7i.
- Comparison operators for < (proper subset) and > (proper superset)
have been added to hashsetof.s7i.
- The type digestAlgorithm and the functions msgDigest, blockSize
and digestSize have been added to msgdigest.s7i.
- The function hex has been added to bytedata.s7i.

socket.s7i, atom.c, entutl.c, soclib.c, soc_rtl.c and striutl.c.
- The padding in the message digest functions of msgdigest.s7i has
been corrected. Now the functions pad nothing instead of 64 bytes,
when the message length is 55 (mod 64).
- The function getHttp in gethttp.s7i has been improved to use
a case-insensitive comparison for HTTP header field names.
- In exec.c the functions eval_arg_list and dump_arg_list have been
improved to avoid reading from freed memory. This occured in very
rare cases.
- The functions find_action (in actutl.c), fltParse (in flt_rtl.c),

have been improved to use the macros MAX_STRI_EXPORT_LEN and
max_utf8_size.
- Interpreter and runtime library have been improved to ignore the
signal SIGPIPE. Writing to a broken pipe or socket raises the
exception FILE_ERROR instead.

to return either SYS_TRUE_OBJECT or SYS_FALSE_OBJECT.
- The program chkccomp.c has been improved to determine the
alignment used by malloc and whether an access to unaligned memory
succeeds.
- Usages of ALLOC_CHUNK in flistutl.h have been improved to allocate
aligned memory the same way as malloc returns aligned memory.
- The program chkccomp.c has been improved to define the macro
'inline', when the C compiler does not support the keyword inline.
- Occurances of 'INLINE' have been replaced with 'inline' in the
files analyze.c, atom.c, big_gmp.c, big_rtl.c, chr_rtl.c, exec.c,
findid.c, infile.c, int_rtl.c, numlit.c, parser.c, rfl_data.c,

- The functions bStriLe, bytesLe, bStriBe and bytesBe have been
added to bytedata.s7i. This functions convert an integer to a
sequence of bytes.

action STR_PUSH. This action is used when a character is appended
to a string (with the operator &:= ).
- The function sendGet has been added to gethttp.s7i.
- The functions str_yy_mm_dd and str_hh_mm_ss have been added to
time.s7i.

compiler. This function is used to simplify the processing
of various statements.
- The functions that process the statement actions BIG_GROW,
BIG_LSHIFT_ASSIGN, BIG_MULT_ASSIGN, BIG_RSHIFT_ASSIGN,
BIG_SHRINK, BLN_CPY, CHR_CPY, CHR_GROW, CHR_SHRINK, ENU_CPY,

Changes:
* A wordfile for Ultraedit and a syntax definition file for Textpad
has been added. Many thanks to Renato Lenzi for providing it. This
files can be found also on his great italian page about Seed7.
* A compilation problem with DJGPP in fil_rtl.c has been fixed
(thanks to "Rugxulo" for pointing it out).
* The keyboard read function getc(KEYBOARD) has been improved to
accept all Unicode characters also under Linux/Unix/BSD. Up do now
the function did only accept Latin-1 characters.
* The keyboard read function getc(KEYBOARD) has been improved to
accept usages of the mouse wheel also under Windows.
* Checks for correct UTF-8 encoding of the program source have been
added. Overlong UTF-8 encodings, UTF-16 surrogate characters and
missing UTF-8 continuation bytes result in a compile time error.

messages, has been improved.
* The FAQ explanations concerning Unicode and automatic casts have
been improved.
* Documentation comments have been added to gzip.s7i and make.s7i.

write the character, if it is printable.
* The example programs pairs.sd7, panic.sd7, tetg.sd7, sokoban.sd7,
sudoku7.sd7, mandelbr.sd7 and wator.sd7 have been changed to use
proportional Seed7 pixmap fonts.
* Tests for the functions lower and upper with cyrillic letters have
been added to chkstr.sd7.
* The libraries console.s7i, pixmap_file.s7i, graph_file.s7i,
file.s7i, editline.s7i, echo.s7i, null_file.s7i, external_file.s7i,
strifile.s7i, stritext.s7i, tee.s7i, window.s7i, reverse.s7i,
lower.s7i and upper.s7i, have been improved to work with
proportional fonts. Proportional font support uses the functions
moveLeft, erase, backSpace, cursorOn and cursorOff.
* The vector font cronos16 has been improved to look more similar to
the font cronos27.
* The bitmap fonts stdFont10, stdFont12, stdFont14, stdFont16,
stdFont18, stdFont20 and stdFont24 have been improved.
* The vector fonts vecFont10 and vecFont18 have been adjusted to look
like the corresponding bitmap fonts.
* The fonts stdFont8, stdFont9 and cronos27 have been improved to use
less spacing between the characters.
* In graph_file.s7i the logic of a writeln after a setPosXY has been
changed. Now the writeln moves one line downward relative to the
position given with setPosXY.
* A description of the subrange operator, which gets an array slice
from a position with maximum length, has been added to the manual.
* A table to map keysym values to Unicode and the function
mapKeysymToUnicode, which does a binary search in this table, have
been added to gkb_x11.c.
* The function gkbGetc in gkb_x11.c has been improved to work without
recursion, to use mapKeysymToUnicode and to recognize cursor keys
in combination with ALT, NUMLOCK and SHIFT.

improved to use the default Unicode case mapping. In other words:
conversions to lower respectively upper case works for all Unicode
characters, which have a case mapping. Characters without case
mapping are left unchanged. The mapping is independend from the
locale. Individual character case mappings cannot be reversed,
because some characters have multiple characters that map to them.
* In the library deflate.s7i the performance of the deflate
compression has been improved by a factor between 5 and 10.
* The performance of the functions str_cmp, str_range and str_substr
in strlib.c has been improved.

strRange, strSubstrSlice and strSubstr in str_rtl.c has been
improved.
* Tests for the string functions compare, lower and upper and for the
index operations head, tail, range and substring have been added to
chkstr.sd7.
* The definition of the macro arrayMaxPos in common.h has been
improved and usages of the macro have been added to arrlib.c and
arr_rtl.c.
* The compiler has been improved to support the actions HSH_IDX2 and
HSH_UPDATE.
* The compiler has been improved to inline code for the actions
STR_HASHCODE, STR_RANGE and STR_SUBSTR.
* The function intStrToBuffer has been added to int_rtl.c. This
function allows conversions from integer to string, without
memory allocation.
* The compiler has been improved to take advantage of the function
intStrToBuffer.
* The functions getGenericValue, getGenericValueToResultExpr,
getTempVariable, beginCastGeneric, endCastGeneric,
beginCastGenericToResultExpr and endCastGenericToResultExpr have
been added to the compiler.
* The functions hsh_idx2 and hsh_update have been added to hshlib.c.
* The functions hshIdxAddr2 and hshUpdate have been added to
hsh_rtl.c
* The macro hashCode has been defined in str_rtl.h and used in
str_rtl.c (function strHashCode) and strlib.c (function
str_hashcode).
* The program chkccomp.c was improved to write a definition of the
macro INLINE to version.h
* The deprecated function 'read_dir' has been removed from the
library "osfiles.s7i". The replacement of 'read_dir' is 'readDir'.

* The files encoding.s7i, gethttp.s7i, scanfile.s7i, scanstri.s7i,
xml_ent.s7i and bas7.sd7 have been changed to use the new function
integer instead of toInt (toInt was an undocumented internal
function).
* Checks for the function integer have been added to chkint.sd7.
* Checks for the function bigInteger have been added to chkbig.sd7.
* The operator sci has been added to to the library complex.s7i. This
operater converts a complex to a string in scientific notation.
* The compiler (s7c) has been improved to support the actions
BIG_PARSE_BASED, TYP_CMP, ENU_CPY, ENU_CREATE and GEN_DESTR.
* The memory management in the interpreter has been improved. Now it
is possible that a destructor is called and the object memory is
not freed. This is used to free the memory of struct objects only,
when the usage_count reaches zero.
* The UNUSED flag was defined in data.h and used to monitor if the
object memory can be freed.
* The compiler has been improved to call the destructor for local
interface objects (In process_local_declaration process_destr_call
is called for INTERFACEOBJECT objects).
* The compiler has been improved to initialize set constants, that
are part of a data structure (In walk_const_list SETOBJECT objects
are added to set_const_table).
* The runtime library has been improved to use the action GEN_DESTR
instead of PRC_NOOP as destructor for integer and other simple
data types.

Changes:
- The FAQ explanations concerning, 'in' parameters and different
behavior of val and ref parameters, have been improved.
- The keyboard read function getc(KEYBOARD) has been improved to
support more function keys and to accept Unicode characters also
under Windows.
- The program calc.sd7 has been improved to accept and display
Unicode characters.
- The automatic memory management has been improved to work also
for the files managed by pollData.
- The function openEditLineLatin1 has been added to editline.s7i.
Only Latin-1 characters are accepted and written to ''outFile''.
Unicode characters beyond ISO Latin-1 (ISO-8859-1) are ignored.
- In file.s7i the function writeln(file, string) has been defined as
DYNAMIC (virtual) function. This allows that the implementation
function writeln(socket, string) sends string and '\n' together.
- The definition of keys in keybd.s7i have been changed such that
function keys are outside the range of Unicode characters.
- The new library keydescr.s7i, which defines a hash table with
descriptive text for function keys, has been added.
- The implementation function writeln(null_file, string) has been
added to null_file.s7i. This function is used by many derived
types.
- An implementation function of writeln(socket, string) has been
added to socket.s7i. This function sends string and '\n' together.
- Definitions of writeln (without string parameter) have been removed
from external_file.s7i, socket.s7i and utf8.s7i.
- The example programs bas7.sd7, gkbd.sd7 and kbd.sd7 have been
changed to use the hash keyDescription (defined in keydescr.s7i).
- Tests for string assignment and string append (operator &:= ) have
been added to chkstr.sd7.
- The function bigStr in big_rtl.c has been improved to realloc the
string to the correct size.
- The function determineEnvironDefines in chkccomp.c has been
improved.
- The function itf_destr in itflib.c has been improved to cooperate
with the function close_stack (defined in name.c).
- The function kbdKeyPressed in kbd_inf.c has been improved to never
wait for input (calls of tcsetattr() were fixed, see below).
- In pol_unx.c and pol_sel.c the functions addCheck, removeCheck,
polCpy, polCreate, polDestr and polClear have been improved to use
the function pointers incrUsageCount and decrUsageCount from
fileObjectOps.
- The function initPollOperations has been added to pol_unx.c,
pol_sel.c and pol_dos.c.
- In str_rtl.c the functions strAppend and strCopy have been changed
to use SLICE_OVERLAPPING instead of GET_SLICE_ORIGIN.
- In str_rtl.c the functions strHeadSlice, strRangeSlice,
strSubstrSlice and strTailSlice have been improved to avoid
(mis)using the string capacity. Now the capacity of a slice is set
to zero. Before the origin of a slice was stored in the capacity.
- The function print_real_value in traceutl.c has been improved to
print interface values with more detail.
- Support for additional function keys has been added to kbd_inf.c,
kbd_poll.c, cap_def.h, trm_cap.c and trm_inf.c.
- The files kbd_inf.c and kbd_poll.c have been improved to use read()
instead of fread().
- The files kbd_inf.c and kbd_poll.c have been improved to take a
weakness of tcsetattr() into account. The function tcsetattr() may
return success, although not all changes could be carried out.
Now the calls of tcsetattr() are done via the new functions
term_descr_equal, tcset_term_descr and tcset_vmin_vtime.
- The compiler has been improved to create and use cpy_... functions
for the interface assignment (action ITF_CPY).
- The free list management for strings has been improved to allow
different maximum list lengths for strings with different capacity.
- Definitions of databasetype and sqlstmttype have been added to
common.h. This are the first steps towards database support.
Feature safe: yes

Changes:
* Interpreter and compiler have been improved to support the option
*l. This option allows adding a directory to the include library
search path (e.g.: -l ../lib).
* The compiler (s7c) has been improved to support the option -b.
With -b the directory of the Seed7 runtime libraries can be
specified (e.g.: -b ../bin).
* The target s7c in the makefiles has been changed to take advantage
of the options -l and -b. Now packages can compile the Seed7
compiler without a post install step.
* Additional function variants of parseFile, parseStri and execute
have been added to the library progs.s7i. The new functions allow
a detailed specification of parse and execution options.
* The library gzip.s7c has been improved to decode also blocks with
fixed Huffman codes. This type of block is almost never used since
dynamic Huffman codes compress better.
* The parsing of bigInteger literals has been improved to support
literals with bases other than 10 (e.g.: 16#FEDCBA98765434210_).
* The integer and bigInteger functions str (conversion to string)
have been changed to use lower case characters for digits larger
than 9. Now str(48879, 16) returns "beef" instead of "BEEF".
* The program make7.sd7 and the library make.s7i have been improved
to support multiple targets and the option -C.
* The Seed7 compiler has been improved to generate special inline
code for the case that the C floating point division by zero does
not result in Infinity, -Infinity or NaN (not a number).
* The functions chkLiteral and chkBitLength as well as checks for
shifts with negative shift count have been added to the program
chkbig.sd7.
* The function check_division as well as has checks for the operator
/:= (in check_nan) have been added to the program chkflt.sd7.
* The function check_str in chkint.sd7 has been improved to check
the new behaviour of the function str with a give base.
* The makefile mk_clang.mak has been added to support compilation
with the clang C compiler.
* The explanations of possible compilation errors in src/read_me.txt
have been improved.
* The functions interpreterPath and callOwnProgram have been removed
from the libraries environment.s7i respectively shell.s7i. This
functions were not used in any example program.
* The support for the interpreter option -m (use less memory during
the analyzing phase) has been removed. On many systems it was a
noop anyway.
* Result variables have been renamed in various libraries and example
programs.
* The functions find_include_file, print_lib_path, append_to_lib_path
and init_lib_path have been moved from infile.c to the new file
libpath.c.
* The function gen_rtl_array has been defined in the new file
arrutl.c. The function is used in the files cmdlib.c (functions
cmd_pipe2, cmd_pty, cmd_start_process) and prglib.c (functions
prg_exec, prg_fil_parse, prg_str_parse).
* The interpreter/compiler improvements (option -l) and the new
function variants in progs.s7i have been realized with changes in
prg_comp.c, analyze.c, data.h, infile.c, infile.h, info.c, option.h
and s7.c.
* The functions prgExec, prgFilParse and prgStrParse in prg_comp.c
have been improved to support additional parse and execution
options.
* The function interpr has been renamed to interpret and moved from
exec.c to prg_comp.c.
* The function copy_args has been moved from prclib.c to prg_comp.c.
* In traceutl.c the function set_trace has been changed and the
function set_trace2 has been removed. The functions mapTraceFlags,
mapTraceFlags2 and set_protfile_name have been added.
* The functions uBigMultiplyAndAdd and bigParseBased have been added
to big_rtl.c:
* In big_gmp.c the functions bigBitLength, bigLShift, bigRShift,
bigLShiftAssign, bigRShiftAssign, bigParse, and bigToInt32 have
been improved and bigParseBased has been added.
* To support bigInteger literals with base the file numlit.c has been

Changes:
* The Seed7 interpreter was renamed. The new name of the Seed7 interpreter
is s7.
* Manual, FAQ, read_me files and several example programs were updated to
use the new name of the Seed7 interpreter (s7).
* The build process of a package can compile interpreter and compiler with
(xx and yy must be replaced with a path):
$ make S7_LIB_DIR=xx SEED7_LIBRARY=yy depend s7 s7c
* The function drwOpen in drw_win.c was improved to hide the console
window, when the program was not started from a console.
* Descriptions of the operators 'sci' and 'exp' were added to the manual.
* Documentation comments were added to clib_file.s7i.
* In pixmap_file.s7i the functions for pixmapFontFiles were improved.

function cmdStartProcess the flag wShowWindow was changed to 1.
* The file hi.c was renamed to s7.c.
* In striutl.c the function escape_command was changed to quote commands
with special characters under windows.
* In striutl.c the function cp_to_command was improved to do a quoting
under windows, even when there are no parameters.
* Parameter names were added to null_file.s7i, osfiles.s7i, time.s7i,
pixmapfont.s7i, progs.s7i, reference.s7i, seed7_05.s7i, shell.s7i,
stritext.s7i, text.s7i, rever.sd7 and snake.sd7.

20121125:
- The makefiles and the file setpaths.c were improved to accept the
macros S7_LIB_DIR (Directory with static Seed7 object libraries)
and SEED7_LIBRARY (Directory with the Seed7 include libraries).
Now the build process of a package can call make e.g. with:
make S7_LIB_DIR=/abc/seed7/bin SEED7_LIBRARY=/abc/seed7/lib depend
This way the two paths are defined in version.h. This defines them
as default paths in the interpreter executable and in the compiler.
- An explanation, what a binary Seed7 package should install, was
added to the FAQ. This can be used as guideline for Seed7 packages.
- The description of the times-operator in the manual and in
array.s7i was improved.
- A description of the function name(PROGRAM), file(PROGRAM) and
'environment' was added to the manual.
- The new library environment.s7i was added. Most of the contents of
this library was extracted from "seed7_05.sd7". The new library is
included from "seed7_05.s7i", so no change in existing programs is
necessary.
- A documentation comment for getSearchPath was added to shell.s7i.
- The functions ltrim and rtrim were added to the library string.s7i.
- Testcases for ltrim and rtrim were added to chkstr.sd7.
- The function getProgramName in arr_rtl.c was improved to do the
comparison with EXECUTABLE_FILE_EXTENSION correctly.
- The program tar7.sd7 was improved to accept also DOS paths for the
file specified with -f.
- The function homeDir was improved to work with DJGPP (either $HOME
or C:\ is used).
- The function prc_cpy in prclib.c was improved.
- The files executl.c, hshlib.c, ref_data.c, reflib.c and sctlib.c
were improved to copy the descriptor union with memcpy and to copy
the posinfo flag with SET_ANY_FLAG, when necessary.
20121104:
- The new function homeDir was added to the library osfiles.s7i.
Interpreter and compiler were improved to support homeDir.
- The libraries makedata.s7i and make.s7i were improved to support
replacement macros.
- A check for division by zero with /:= was added to chkflt.sd7.
- The compiler (comp.sd7) was improved to use definitions of
NOT_A_NUMBER, POSITIVE_INFINITY and NEGATIVE_INFINITY.
- The program chkccomp.c was improved. Now it manages the macros
likely, unlikely, UNISTD_H_PRESENT, POPEN_MISSING, os_utime_orig,
os_utime, USE_ALTERNATE_UTIME, INCLUDE_SYS_UTIME, USE_LOCALTIME_R,
USE_LOCALTIME_S, FLOAT_ZERO_DIV_ERROR, CHECK_FLOAT_DIV_BY_ZERO,
ISNAN_WITH_UNDERLINE and HOME_DIR_ENV_VAR. Additionally chkccomp.c
does not depend on the definitions of long_long_EXISTS,
long_long_SUFFIX_LL, __int64_EXISTS, __int64_SUFFIX_LL and
USE_BUILTIN_EXPECT in chkccomp.h.
- The functions flt_div and flt_div_assign in fltlib.c were improved
to work correctly when CHECK_FLOAT_DIV_BY_ZERO is defined.
- Several #defines were ommitted from the makefiles.
- Explanations of several version.h #defines were added to
read_me.txt
Feature safe: yes

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.

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.
