Howdy All,

Happy Canada Day and Happy Independence Day (this week) for those
countries that observe that holiday.

Until today I hadn't had the time to finish off the new MS Windows
installer, but I did manage to get that task done.

Download from:

http://www.gnubg.org/media/windows/gnubg-1_01_000-20130701-setup.exe

It is recommended (but not required) that you install into a new
directory or uninstall the older release.

The Installer changes:
- Installer will only install on Windows 2000 SP4 or higher
- Installer no longer needs to run as an elevated user privilege (Power
User or Admin). If running as a standard user it will install itself
into the application directory in the users home directory
- If you wish to install as Admin (On Vista or newer OSes), download the
setup and in MS Windows file explorer right mouse click on the setup and
use "Run as Administrator". You will need to do this if you wish to
install to \Program Files (x86).
- After accepting the license a new page has been added on systems where
your processor may support SIMD instructions (for improved performance).
If your using an antiquated processor with no SIMD support (SSE2 and
AVX) the option page will not be available and will default to the
universal i386 executables (no SIMD support).
- AVX support is listed as EXPERIMENTAL, and at present will not be the
default for systems with AVX CPU and OS Support.
- The supported SIMD instructions of your OS and CPU is displayed at the
bottom of this new options page.
- If you have an AVX processor you also need to be running MS Windows 7
SP1 or higher for this option to be available.
- If installing into a directory with an existing install, you are asked
if you wish to run the uninstaller (if present) in the installation
directory
- At the end of the installation process a command window will appear
while the Python modules are compiled. This is normal.
- If installing into a directory with an older installation without
doing a proper uninstall, the new installer will delete specific files
from older installations that may interfere with proper installation of
the new version.
- The Uninstall process has been fixed to properly search for the users
.gnubg preferences directory.


The ChangeLog is attached for the changes since the 1.00.000 release.
The primary changes from the user perspective are:

- For MS-Windows the minimum required OS is MS Windows 2000 SP4.
- Experimental AVX (SIMD instructions) for the neural net code has been
added by Philippe Michel, and I created the infrastructure to support it
for the build process.
- Python has been upgraded to 2.7.5.
- The Python environment is a complete set of libraries including TK.
- Support for Python IDLE (Python Integrated Development environment).
For those who wish to use this feature, load the GUI, turn on the
"command" panel (View/Panels>/Command). Enter a > (greater than sign)
and hit enter in the command box in the bottom right of the GNUBG main
window.
- Readline support (command completion, and history) is available for
those who install on MS Windows XP SP2 and above while running
gnubg-cli.exe (Command line interface) version.
- GNUBG Python scripts have been moved to the scripts/ sub-directory. If
you wish to change the command line interpreter or the GUI processing it
has been moved to functions in scripts/gnubg.py
- When GNUBG is loaded it will attempt to load (if it exists)
scripts/gnubg_user.py . You can place your own user defined functions
into that file to have them automatically loaded. This file won't be
deleted during an uninstall.
- MySQL support in MS Windows was fixed (had been broken for quite
sometime). Postgres support never worked on MS Windows so has been
removed for that platform.
- Database options allows hostname:portnumber to be specified for MySQL
(And Postgres on platforms where it is supported)
- The No SSE version of gnubg.exe and gnubg-cli.exe have a maximum
support for 4 threads to save on memory for older systems with limited
resources.
- New functionality to support a new GNUBG Python Module 'hint'
function. This produces hint information (limited to move hints, but not
cubes) and returns a hint dictionary.
- Board preferences are saved when clicking OK on the Board preferences
option screen.
- Alternate Language support was broken in 1.00.000, and has now been fixed.
- Other minor bug fixes reported by users and developers.

Other notes On *nix/BSD platforms:
- With IPython installed, IPython will be the default command line
interpreter.
- MySQL and Postgres player database support has been fixed.
- autoconf --enable-sse has been renamed --enable-simd . Also supports
type avx . SIMD support is on by default.
--enable-simd=TYPE/--disable-simd are used to override it.
- autoconf --enable-cputest has been cleaned up
- autoconf processing better detects the CPU SIMD capabilities of the
build environment.

If you encounter problems with the new installer please contact me. Many
issues were resolved with the help of various computers/OSes. Thanks for
the testing by Ian Shaw and Philippe Michel.

If things look okay I will use this release and installer for the
official 1.00 announcement on the GNUBG webpages.

Thanks

    * eval.h, rollout.c, gnubgmodule.c:  Store the JSD that a 
    rollout alternative was stopped on into the rollout context

    dbprovider.c gnubg.c gnubgmodule.c gnubgmodule.h: Allow a
    user Python startup script (gnubg_user.py) to be loaded
    at startup AFTER gnubg.py. No error is thrown if the file
    doesn't exist. gnubg_user.py is not meant to be imported,
    but loaded as a textfile into the main name space just like
    gnubg.py .

2013-06-29  Michael Petch  <[email protected]>

    * backgammon.h, gnubg.c, gnubgmodule.c: Added preliminary 
    support for Python module function 'hint'. Work in progress
    The function interface and the dictionary returned may change.
    Added module functions mwc2eq_stderr and eq2mwc_stderr.

    Inefficient memory use for eval and rollout contexts should be 
    cleaned up. Rollout contexts should include all the cube and 
    chequer play sub contexts. The hint dictionary needs to be
    documented.

2013-06-25  Michael Petch  <[email protected]>

    * backgammon.h, gnubg.c, play.c: hint_move has been modified to 
    support external callbacks. Part of future Python integration.

2013-06-25  Michael Petch  <[email protected]>

    * eval.c, lib/neuralnet.c: If SIMD instructions are compiled in
    and they are not supported by the processor, output an error 
    message and then terminate immediately.

2013-06-22  Michael Petch  <[email protected]>

    * INSTALL, configure.ac, eval.c, gnubg.c, gnubg.spec, 
      po/POTFILES.in
    Rename file sse.h to simd.h. Rename USE_SSE_VECTORIZE to 
    USE_SIMD_INSTRUCTIONS, rename SSE_Supported to SIMD_Supported,
    rename DISABLE_SSE_TEST to DISABLE_SIMD_TEST,
    rename SSE_CFLAGS to SIMD_CFLAGS

    Make sse/simd usage more consistent, ./configure option
    --enable-sse/--disable-sse is now --enable-simd/--disable-simd

2013-06-20  Michael Petch  <[email protected]>

    * +m4/ax_check_compile_flag.m4, +m4/ax_ext.m4 
    +m4/ax_gcc_x86_avx_xgetbv.m4 +m4/ax_gcc_x86_cpuid.m4,
    configure.ac: Added better autoconf support to determine 
    whether the processor supports certain SIMD instruction sets
    like SSE,SSE2,AVX etc.

    --enable-simd behaves a bit different. --enable-simd with no
    parameters is the same as --enable-simd=yes . The behavior of
    --enable-simd=yes has been changed to find the latest supported
    SIMD instruction set used by the build machines CPU. Priority
    is given in this order (highest first): SSE2, SSE, AVX, None.
    Since AVX is still experimental it is not given priority over
    SSE2 during build time autodetection.

2013-06-19  Michael Petch  <[email protected]>

    * +output.c +output.h, gnubg.c, backgammon.h, lib/Makefile.am
    lib/neuralnet.c: Moved the output functions from gnubg.c to
    their own files.

2013-06-19  Michael Petch  <[email protected]>

        * gnubg.c, eval.c, lib/neuralnet.c, lib/neuralnet.h,
        configure.ac: Add support for plm's new AVX instruction
        additions. Separate the cputest from the --enable-simd
        configure option. Created a new option --disable-cputest. 

    Supports cputest functionality on GCC builds with either
    64-bit or 32-Bit OSes on Intel processors. Code will work
    with builds that use -fpic option.

2013-06-18  Michael Petch  <[email protected]>

        * gnubg.c: When using the -r flag to start GNUBG (start without 
        reading the gnubgautorc file), the gnugbautorc file will be
        overwritten with defaults if running with the GUI. Reported
        by plm, see: https://savannah.gnu.org/bugs/?38497#postcomment

2013-06-17  Michael Petch  <[email protected]>

        * gtkgame.c: Fix language bug that prevented the GUI from properly
        refreshing the screen when a new Language was chosen

        * Makefile.am: Win32 builds have a localedir of ./locale relative
        to the executables directory. A bug had newer windows builds 
        seeking locale files in the default locations which was incorrect,
        and consquently language translation didn't occur.

2013-06-15  Michael Petch  <[email protected]>

        * All .c and .h files: Standardized the code formatting with
         indent -kr -l120 -fc1 -sc -nut -psl . K&R style, 120 column limit
        process comment in column 1, multiline comments have an asterisk 
        at the beginning of each line, convert all tabs to spaces, and
        split the return type of a function from the function name
        (each on their own line). K&R uses 4 spaces for an indentation
        level. Update the language files.

        * script/*.py : Reformat the python files to conform to PEP8 
        standard. See http://www.python.org/dev/peps/pep-0008/#indentation

2013-06-15  Michael Petch  <[email protected]>

        * gnubgmodule.c, scripts/gnubg.py: Modify the python interpreter
        processing so that it falls back to a simple command line
        interface on older versions of Windows (Versions before WinXP SP2).
        Fix segfault related to launching the Python command line 
        interpreter

2013-06-15  Philippe Michel  <[email protected]>

        * configure.ac, lib/neuralnetsse.c, lib/sse.h, lib/inputs.c: Use
        AVX instructions when built with "configure --enable-simd=avx"

2013-06-13  Michael Petch  <[email protected]>

        * gtkprefs.c: Save board preferences when clicking "OK"
        on the board appearance configuration dialog.

2013-06-12  Michael Petch  <[email protected]>

        * dbprovider.c, dbprovider.h, gtkrelational.c, relational.c,
          scripts/database.py : Allow hostname to be specified
        in the database connection dialog box. Hostnames can be
        any valid combination of hostname:portnumber

2013-06-07  Michael Petch  <[email protected]>

        * gtkwindows.c, play.c: Fix a bug that segfaulted the "end game"
        command when built with GTK and the "-t" option is used to
        launch GNUBG.

2013-06-06  Michael Petch  <[email protected]>

        * gnubgmodule.c, gnubgmodule.h, gtkgame.c, scripts/gnubg.py: Move
        loading of the Python command line interpreter to Python functions
        in gnubg.py. The Python command line now supports IPython if
        present. IPython takes precedence over the standard Python 
        interpreter. If the standard interpreter is used, attempt to
        load command history (readline module) and then try loading
        auto completion (rlcompleter module) support if present.        

        Fix Python related ifdefs to allow compiling when built without 
        Python support.

2013-06-05  Michael Petch  <[email protected]>

        * scripts/gnubg.py: Add the scripts directory to the Python path
        so that files in the directory can be imported.

2013-06-05  Michael Petch  <[email protected]>

        * gnubgmodule.c, gtkgame.c, play.c: Modify the interactive Python 
        interpreter to support tab completion and command history. Begin
        reintroducing Python IDLE, since it functions on MS Windows and
        various linux distros. Ubuntu/Debian installation of IDLE can be 
        done via: apt-get install idle . If IDLE is not present it will
        drop back to the old method. CLI builds don't use IDLE at present.
        IDLE is not on the GUI menu but can be activated by turning on the
        "command" pane and entering '>' (greater than sign without quotes)
        as a command. IF IDLE is not presnt and usable it will do nothing.
        This is a work in progress.

2013-06-04  Michael Petch  <[email protected]>

        * gtkrelational.c: Don't allow a user to create a player database 
        that already exists.

        * dbprovider.h, dbprovider.c, scripts/database.py, gnubgmodule.c:
        Add Mysql support on Win32 platforms using pymysql (a purely
        python based database driver for mysql)

2013-06-04  Michael Petch  <[email protected]>

        * configure.ac, multithread.h: Allow a new autoconf/configure 
        parameter --with-eval-max-threads=size to allow the maximum number of
        evaluation threads to be specified. Default is 48 if not specified.

        * dbprovider.h, dbprovider.c, relational.c scripts/database.py:
        Fix bugs that prevented proper connections and database usage 
        when using the Mysql and Postgres player database providers. 
        Mysql and Postgres are unsupported on the MS Windows platform - 
        Disable them in the GUI

2013-05-31  Michael Petch  <[email protected]>

        * play.c: Under certain situations (load commands from a file 
        containing a play command within the GUI) would stop
        on an assertion. PlayCommand not properly resetting the
        notification handler. Reported by Ian Shaw

2013-05-28  Michael Petch  <[email protected]>

        * gnubg.c: Fix bugs related to python handling of
        ParseMove and FormatMove . Fix bug that would cause crash when 
        command "load commands" used unquoted filenames on Win32 platform.
        Reported by Ian Shaw
