You can find the downloads for binaries and preconfigured installer packages of Winboard atthe Winboard Forum,where you can also report problems, get help from other WinBoard users or discuss feature requests.Windows builds of development versions or installers for special configurationscan be found at HGM's web page.
Development for Winboard, reporting bugs and any other requests canalso be done at the same places as for XBoard (see below).
Downloading XBoard
Stable version (4.9.0)
Sources of the current stable version are available from the main GNUdownload server(HTTPS, HTTP, FTP) and itsmirrors; pleaseuse a mirror if possible.

For information about development, please seethe XBoard projectpage at savannah.gnu.org.
We regularly do so-called 'developer releases', which includethe newest and the latest we are working on.If you want to help us test, or just want to use thenew features, you might prefer to use those over the stable version.
At the Open Build Server we provide packages that can be installed in parallelto the normal xboard version. To do this the programs are renamed toxboardnext (latest from the v4.9.x branch in Git) and xboardgit (latestversion from the master branch in Git). Packages are available for:Debian 6.0, Fedora 17/18, RedHat RHEL 6,openSUSE 12.1/12.2/12.3/Tumbleweed/Factory, CentOS 6, Arch,Ubuntu 10.04/12.04/12.10.

Windows builds of development versions can often be found at HGM's web page.
Furthermore we provide development versions (tagged commits in Git):
a snapshot of the master branch: master-20140119;
no developer release at the moment.
How to build the development version
Git version
The Gitrepository is on Savannah. All branches can be viewed on its webinterface, which also provides tarballs of all tagged versions. Thesetarballs are different from the ones that you can download from the GNU server, and you willneed to run ./autogen.sh on them as described below.
If you want to get a copy of the repository, you can clone it using the following command:
For more information on how to use Git, please visit the Git home page.
After cloning the Git repository or downloading and unpacking a snapshottarball from the Git repository,run ./autogen.sh, ./configure, and then makeand make install.
Tarballs from the download server
Unpack the tarball and do ./configure followed bymake and make install.

Archive
You can also find an archive of old versions on the FTP server.
Documentation
The official manual page for XBoard is available online,as is documentation for most GNU software.This discusses every feature XBoard has in detail.You may also find this information on your local system byrunning info xboard or man xboard, or bylooking at /usr/doc/xboard/,/usr/local/doc/xboard/, or similar directories on your system.
There now also exists an XBoard UserGuide, which only presents the main features in a more pedestrian way.This would be an excellent starting point if you are a novice XBoard user.If you have prior experience with XBoard, but just want to know what newfeatures have been added since the version you were used to,the pages in the What's New section wouldbe the place to go.
A description of the Chess Engine CommunicationProtocol used by XBoard to communicate with Chess Engines is also available.
Screenshots
These are screenshots taken from version 4.4.0 (click to enlarge).
Help needed
It would be great if people would like to help in the developing processWe can use all kinds of help, from people who just use the software and havea feature request (send them to developer mailing list), to people who canupdate/check the documentation and especially people who test developmentversions (send problems to the developer mailing list).Have a look at the following list in case you are interested:
Admin
A new project admin is needed. The person would manage the Savannahpages, membership to Savannah/Git access, do releases, and manage the emaillist, etc. The job could also be split among several people.
Translators
We added support for different languages to XBoard and need people totranslate it. The translation is handled by the translationproject. You can check on the current statusand how to join the translation project.
Testers
We are always looking for people who are willing to test the latest newfeatures and give us feedback or new ideas. If you are interested, pleasesend an email to our list at <[email protected]> or just tryout the program and reports bugs either to the email list or to the bugtracker (see below for links).
GTK developer needed
We are also working on merging Winboard and XBoard back into one versionusing a cross platform GTK-front end. This will help us clean up the codeand make things like internationalization easier. We made some progress, ifyou know want to help out there are still lots of things waiting to be done.Email the mailing list for moreinformation. There is already some unmerged code to port to GTK3.
Update the help files
The help files for Xboard and Winboard could be merged into one document.
Update the webpage
The content of the webpage could be updated with screenshots fromthe latest version. We also have a new tutorial that could beintegrated.
Links
