*******************************************************************************
Octave 2.09 Build 03:
**********************
* mkfifo is now supported.

* The documentation is now also available in OS/2's INF format. You can
view them using gnuview as Octave's external info viewer.
* Compiler updated (EMXFIX03).
* Bug in logm (wrong result for a complex scalar argument) fixed.
* Minor changes in the sources and makefiles.
* Workaround for the bug in the fortran routine DGELSS added (in CMatrix.cc).
* Patch included:
* idx-vector.cc (IDX_VEC_REP::sort): New function.
* idx-vector.h (idx_vector::sort): Ditto.
* Array2-idx.h (Array2<T>::maybe_delete_elements): Use it before
trying to delete elements specified by the index vectors.
Octave 2.09 Build 02:
**********************
* Bug in cruft4.def fixed, which caused Octave to crash, when trying to
compute eig(A), with a complex matrix A.
Octave 2.09 Build 01:
**********************
* New Version 2.0.9.
Octave 2.08 Build 01:

* Patches included:
input.cc (octave_read):
Don't forget to free input buffer if it exists and has zero length.
(gnu_readline):
Free buf if fgets returns 0.
parse.y:
Parse error will not abort Octave, when forced_interactive "-i"
Array2-idx.h (Array2<T>::maybe_delete_elements):
Prevent out-of-bounds indexing of the index array.
Array-idx.h (Array<T>::maybe_delete_elements): Likewise.
idx-vector.cc (IDX_VEC_REP::is_colon_equiv):
Make it work when the vector is not sorted.
Octave 2.05 Build 03:
**********************
* lex.l patched:
help will work with text mode files, even if the help text is not at the
beginning of the file.
* Lisp files modified:
hilit19 will not be loaded, when running emacs in normal text mode.
* parse.y patch included:
Using formal parameters for functions, the names of which are already
being used by builtin functions, will not produce errors. For example:
function y=f(type), y=type; end;
* variables.cc patched: <CR>s are not copied into the help text.
* The full name of the executable can be specified in .emacs.
* inst-octave.cmd and updt-octave.cmd patched.
* lex.l patched: Octave reads script and function files with lines like:
x = x + ...
3;
Octave 2.05 Build 02:
**********************
* New internal system routine (also used in procbuf):
All / in the executable are replaced by \ when using cmd.exe or 4os2.exe
as shell and all \ are replaced by / when using a UNIX shell.
* make-octfile.cmd patched: The dynamic loading of function will
under OS/2 2.xx.
* nextpow2.m patched: nextpow2(1000) returns 10.
* inst-octave.cmd patched: scripts.fat will be renamed to scripts on FAT.
* The files in the subdirectory doc are FAT compatible.
* Octave reads script and function files with lines like:
M = [1 2
3 4]
Octave 2.05 Build 01:
**********************
* New version: Octave 2.0.5
* help will work with text (<CR>>LF>) files.
* No endfunction is needed at the end of a function file.
* Octave uses noncontinous multiple heaps. So the heap size is no longer
fixed to 32 MB.
* Image viewer and GNUPlot can be used at the same time again.
The environment variable OCTAVE_IMAGE_VIEWER is supported again.
* (require 'hilit19) added in lisp files.
* octave-mode.el modified: switch/case/otherwise/endswitch statement included.
Octave 2.02 Build 02:
**********************
* Bug in usleep fixed. plot works again.
* erf(x) and erfc(x) are supported. Bug in erfinv.m is fixed.
* gamma(2000) no longer aborts Octave.
* Bugfixes in the installationsscript. Corrected README.OS2
* Default value of IMAGEPATH now points to ../scripts/image.
* Patch included (oct-stream.cc):
scanf reads correctly when using %f or %e.
Octave 2.02 Build 01:
**********************
* POPEN2.M modified: The script now uses the new function spawn to start
the child process.
* The environment variable OCTAVE_IMAGE_VIEWER is no longer supported. Modify
the script file IMAGE.M, if you want to use another image viewer.
* Function added: child_purge_temp_file. It removes the temporary file
when the specified child process dies (used in IMAGE.M).
* The pipe function returns the file handles and not the Octave's file ids.
Use fdopen to open the handles!
* Functions added: dup, close, fdopen.
* Function added: spawn.
* Octave reads OS/2 BMP (version 1.0) Windows BMP, PNM (P1 - P6) and
Octave's IMG format. It writes OS/2 BMP (version 1.0) Windows BMP,
PNM (P5, P6), Postscript and Octave's IMG format. LOADIMAGE.M and
SAVEIMAGE.M are modified (the original version are in the archive
image.zip).
* New version: Octave 2.0.2
* Bug fixes in dlfcn.lib.
Octave 2.01 Build 01:
**********************
* Dynamik Linking is now supported! See hello.cc and make_int.cc for
example. A small bug in make_int.cc fixed.
* Bug in xor.m fixed.
* Bug in the installation script fixed: The script will not replace the first
"\DLL" in LIBPATH, if Octave is installed for the first time on a system.
* The installation script is renamed to inst-octave.cmd.
* New version 2.0.1.
* All C++ Code is now placed in DLLs.
* GNUPLOT is started as normal VIO, so gshow will work. Also because of other
changes in the code, CTRL-C works even when GNUPLOT is started.
* Minor changes in the sources.
Octave 2.00 Build 01:
**********************
* New version: Octave 2.0.
* Script and function files are loaded correctly even if they contain an
End-of-file character. This character will be interpreted as a newline
character.
* saveimage saves images in bmp, gif and ps files.
*******************************************************************************
** Changes since the Version 1.1.1 of Octave for OS/2 **
*******************************************************************************
Octave 1.94 Build 01:
**********************
* New version 1.94 (pre-2.0). Keep in mind:
***************************************************************************
** Octave 1.94 is a test release! **
** If you have any problems, please report them, so that they can be **
** fixed in version 2.0 **
***************************************************************************
* New command line flag '-I'. It forces interactive behaviour, but
deactivates the pager, even if Octave is in interactive mode.
* Every signal which will cause a jump to toplevel (Octave prompt), will
be handled differently if a script or function file is executed: It will
be handled as an error.
* A new installation script: This script make changes in the config.sys,
.octaverc, .emacs and dir. It unzips the scriptfiles and creates an object
on the desktop! The info-files will be copied to the correct directory
and older DLLs coming with EMX will be removed, if necessary.
Octave 1.93 Build 02:
**********************
* Script and function files are loaded correctly even if they no text file
(CR/LF).
* The sigchld_handler in sighandlers.cc is patched:
When no child in octave_child_list has created SIGCHLD, waitpid is
executed. This solves problems with displaying images when GNUPLOT is
running, and similar problems.
* Octave's system command now correctly returns the output or the pid,
depending on the number or values of the arguments.
* The image viewer is started in "async" mode.
Octave 1.93 Build 01:
**********************
* New version 1.93 (pre-2.0). Keep in mind:
***************************************************************************
** Octave 1.93 is a test release! **
** If you have any problems, please report them, so that they can be **
** fixed in version 2.0 **
***************************************************************************
* Changes in octave.el: hilit19 is used for octave-shell-mode.
Octave 1.92 Build 02:
**********************
* get_size () in oct-stream.cc patched:
fread works with a scalar as second argument.
* Function kbhit () in sysdep.cc calls flush_octave_stdout.
* sighandlers.cc and toplev.cc patched:
Ctrl-C and Ctrl-Break will work more than only once again.
Octave 1.92 Build 01:
**********************
* New version 1.92 (pre-2.0). Keep in mind:
***************************************************************************
** Octave 1.92 is a test release! **
** If you have any problems, please report them, so that they can be **
** fixed in version 2.0 **
***************************************************************************
* Minor bug fixes in octave-info.el.
* Changes in octave-mode.el: hilit19 is used for editing script files.
* New command add to the Emacs-Shell-Mode for Octave: warranty, multiplot,
close multiplot, subwindow.
* Minor changes in the the makefiles for OS/2. These changes do not
modify the binary.
Octave 1.91 Build 01:
**********************
* New version 1.91 (pre-2.0). Keep in mind:
***************************************************************************
** Octave 1.91 is a test release! **
** If you have any problems, please report them, so that they can be **
** fixed in version 2.0 **
***************************************************************************
Octave 1.90 Build 01:
**********************
* New version 1.90 (pre-2.0). Keep in mind:
***************************************************************************
** Octave 1.90 is a test release! **
** If you have any problems, please report them, so that they can be **
** fixed in version 2.0 **
***************************************************************************
* New libraries (readline, kpathsea).
* Octave uses again an internal info viewer. This ensures that it runs
correctly under the control of Emacs.
* Signal handler for SIGCHLD gepatcht.
* Octave needs the GNUPLOT 3.6 beta to display multiple plots.
* Since the new compiler supports multiple heaps it is no longer
necessary to fix the heap size during the installation.
* The environment variable specifies the name of the init file octave executes
on startup.
*******************************************************************************
** Changes since the Version 1.1.0 of Octave for OS/2 **
*******************************************************************************
Octave 1.1.1 Build 08:
**********************
* The cursor type will be selected in readline.
* New Compiler (emx-gcc 0.9c) and libraries used.
* The Stacksize has been increased.
* Signal handling is improved: Ctrl-Break always acts in the same way Ctrl-C
does. No signal handler for SIGTERM!
Octave 1.1.1 Build 07:
**********************
* All FPE signals are now explicity masked off. The fixes the bugs when
running Octave on systems with GAMESRVR.DLL.
Octave 1.1.1 Build 06:
**********************
* Pause now works also when running Octave under Emacs.
* The Octave's 'system' (or 'shell_cmd') is fixed. This fixes also the bug in
saveimage.
* xvos2 now uses the image viewer specified in the environment variable
OCTAVE_IMAGE_VIEWER, if set, or ib.exe if not.
Octave 1.1.1 Build 05:
**********************
* New Compiler (emx-gcc 0.9B) and libraries (stdcpp, libg++, ...)
* New info browser version 2.14
* parse.y was patched:
A parse error will not abort the parser, if octave is forced to be
interactive (-i).
* lex.l was patched:
SIGINT will not crash Octave, if octave is forced to be interactive (-i).
* info will not kill the octave process, if the terminal type is emacs.
It displays a message, so that emacs can start its own info browser.
* The routines read and write in liboctave/dMatrix.cc are patched:
The streams are set to binary mode before writing/reading and set back to
text mode after.
* Emacs-Shell-Mode for Octave including Info, temporary files, script files.
* New function in Octave: add_to_command_number.
Octave 1.1.1 Build 04:
**********************
* image uses now ib.exe (the Multimedia Viewer coming with Warp) to view
the images. This works also when GNUPLOT is running.
* GNUPLOT is now started as PM program in a different session. Now one can
use Ctrl-C to interrupt Octave, when Gnuplot is running.
* Internal Changes in Iostream:
New function _io_popen (used in the member functions of the class procbuf):
The command is now executed direct, without the command processor cmd.exe
(or ...). The way the program is started (PM, Session, ...) is specified
in the third argument of _io_popen. If this fails, the command is
executed via the command processor.
* A new signal handler (SIGINT) for parse_and_execute: The script files
are closed, if the execution is interrupted by the user. The signal works
like an error!
Octave 1.1.1 Build 03:
**********************
* The signal handler is fixed: Ctrl-C works now more than only ones.
Octave 1.1.1 Build 02:
**********************
* The function script polyreduce.m is fixed. So the functions deconv and
residue are working.
* The Fortran and C routines are now in DLLs. This reduces the size of the
executable and octave needs not so much memory at start time.
* The libraries of info, kpathsea and readline are linked using DLLs. The
stand-alone info browser (info.exe) uses also that DLLs.
* The heap is not longer fixed to 32 MB (by emx gcc). The user can select the
best heap size for his problems and his system.
* The iostream library is fixed: Octave reads binary files (load -b or
load -m).
* A few changes in the source code.
* New Version of Octave (1.1.1).
* Octave no longer hangs the WPS, if it is closed by typing quit, while
GNUPLOTPM is still running.
*******************************************************************************
** Changes since the Version 1.0 of Octave for OS/2 **
*******************************************************************************
* Octave now uses ';' as separator in paths.
* Drives are now supported in paths. So you can start octave from a
different drive and octave will find the script files.
* Drives are also supported in 'cd' and 'pwd'.
* Control-C works more than once.
* By defining USE_EXTERNAL_TEMPLATES and using emxbind -s I made the file
octave.exe much smaller.
* The temporary files created by the commands edit_history and run_history
are deleted.
* The info files are changed for FAT.
* I create a second set of script files, patched for FAT.
* Octave uses the file in the environment variable OCTAVE_INITFILE instead
of .octaverc, if the variable is set.
* New Version of Octave (Version 1.1.0)
* New Compiler (emx-gcc 0.9A) and libraries (iostream 0.66)
* I add the extproc-statement.
* Octave executes now a interactive script from a file in the command line.
* Images can be viewed using ghostscript.
* Octave uses now GNUPLOT 3.5.
