XBoard is a graphical user interface for chess in all its major forms, including international chess, xiangqi (Chinese chess) and shogi (Japanese chess), in addition to many minor variants such as Losers Chess, Crazyhouse, Chess960 and Capabanca Chess. It displays a chessboard on the screen, accepts moves made with the mouse, and loads and saves games in Portable Game Notation (PGN). It serves as a front-end for many different chess services, including:

+ +Development for Winboard, reporting bugs and any other requests can +also be done at the same places as for XBoard (see below).
+ +Starting from 4.5.0 we will summarize the latest changes at these webpages. You can also find information about the next upcoming release here. +Have a look, try it out (download links below) and let us know what you think.
+ +We can always need more people to help out with XBoard/Winboard. Have a look at the following list in case you are interested:
+ +We are always looking for people who are willing to test the latest new features and give us feedback or new ideas. If you are interested, please send an email to our list at <xboard-devel@gnu.org> or just try out the program and reports bugs either to the email list or to the bug-tracker (see below for links).
+ +We are also working on merging Winboard and XBoard back into one version using a cross platform GTK-front end. This will help us clean up the code and make things like internationalization easier. Progress is slow though, so if you know want to help out there are lots of things waiting to be done. Email the mailing list for more information.
+ +A sort of match mode where one engine automatically does a number of 'games', +(using a position file filled with EPDs as starting positions), +except that each 'game' lasts only for one move, and the 'result' is then computed +by XBoard depending on if this move was the correct solution specified in the EPD.
+ +Implement a slave mode where XBoard forks itself, connecting a pipe between +what normally would be the ICS socket of the child, and a new output channel +of the parent, so that the parent can forward board and move lists belonging to +a specific game to the slave dedicated to display it.
+ +A tricky issue, because in the current code initializing the engine is intertwined +with initializing XBoard. And the whole idea is to be able to switch engine without +losing your current settings or indeed your current game. So it will require some +good thought about which options need to be reset (like -fd, for sure), and which +should be kept.
+ +Currently XBoard supports only two-player matches. If run-time changing of the +engine becomes possible, it wold be nice if people could also perform automatic +round-robins or gauntlets between a group of engines.
+ +Currently XBoard just displays what the engine prints for PV in its thinking output +literally. Which often means long algebraic. It would be nice if the user can choose +the display format, so it can be SAN or even some other format (e.g. descriptive +notation or some specific Xangqi or Shogi format), possibly through invoking an +external processor.
+ +The documentation could need some updates. In our effort to merge +Winboard and XBoard back together, we also want to merge the RTF file +back into the XBoard texinfo file. This will take some effort though, +since the two versions still differ in several areas and this would +need to be highlighted. The benefit would be though that we could +prepare a much better and up to date Windows documentation. +

+ +It would be great if people would like to help in the developing process. We can use all kinds of help, from people who just use the software and have a feature request (send them to developer mailing list), to people who can update/check the documentation and especially people who test development versions (send problems to the developer mailing list).
+ +At the moment we have three developer versions:
+After cloning the git-repository, do ./autogen.sh, ./configure and then a make.
+ +Unpack the tar ball and do ./configure followed by make.
