Note that WinBoard 4.5 has been superceded by WinBoard 4.6 as stable version.WinBoard / XBoard 4.5.3
WinBoard 4.5 is the follow-up line of WinBoard 4.4, which ended with version 4.4.4. A special version is available for visually impaired people, for working with the JAWS screen reader, but for now the old 4.5.2 is the latest JAWS version available. (See the post below or click here
to get there.) WinBoard 4.5.3 is a bugfix release, i.e. apart from fixing bugs that were discovered, it is the same as 4.5.2.
WinBoard 4.5 contains many new features compared to version 4.4.x. WinBoard 4.5 can be downloaded as an installer package from here. This installer contains all essential support programs, such as Polyglot and PSWBTM, pre-installed and ready to run. In this respect it is similar to the WinBoard 4.3 Gold Pack. It contains two demo engines, a native WinBoard engine (Fairy-Max 4.8) and a UCI engine (Fruit 2.1). The 4.5.3 installer also contains adapters for running Xiangqi UCI and UCCI engines, and Shogi USI engines, and optional engines for these and other Chess variants.
There also exist various experimental WinBoard versions. The 4.5-TM version is what probably will become the next stable version, which we are preparing for a release as 4.6.0. Compared to 4.5 it contains many enhancements
, including a built-in tournament managers, on-the-fly engine loading, and the posibility to search a loaded PGN file for a specific position.Download WinBoard 4.5.3 installer

This installer also contains optional sections for using WinBoard as a Xiangqi (Chinese Chess) GUI, and engines for Shogi (Japanese Chess), and for general Chess Variant afficionados. For more information about the Xiangqi capabilities of WinBoard, look here
. The variants section provides engines for in total more than 20 widely different Chess Variants (most of them through the Fairy-Max and Pulsar engines), ranging from Chess960 and Gothic Chess to Crazyhouse, Losers and Atomic. For the exact rules of these games, see http://www.chessvariants.org
The source code for WinBord 4.5.3 and previous versions can be obtained from the GNU website
. Use the tar ball that is tagged 4.5.3 (xboard-4.5.3.tar.gz). Most unzippers should understand this format (e.g. 7Zip).What is New?
An eleborate description of the new features can be found on the GNU web pages
. Special mention deserve the fact that every user now has his own settings (winboard.ini) file, the ability to walk variation trees and engine PV, and ICS improvements like a seek graph and a dual-board display for bughouse.
The differences between 4.5.3 and 4.5.2 are tiny. A complete overview of all bugfixes
can be found on the GNU website. In the package there now is an (optional) Dutch language file
. Note that the UCI support built in this WinBoard version can only be fully exploited with Michel van den Bergh's recent Polyglot versions (which are of course included in the 4.5.3 installer pack). These can be obtained as source, Windows and Linux binaries from:Polyglot downloadsXBoard 4.5.3
Version 4.5.3 also includes a new XBoard. This of course supports all the new back-end features. The 4.5.x series also implements several command-line options that were already avaiable in WinBoard, but (for no good reason) not in XBoard. XBoard 4.5.x has persistent settings, like WinBoard, and an evaluation-graph window. XBoard 4.5.3 will be available from Debian and Ubuntu repositories. A Debian package should also be available from the GNU XBoard home page. People using other Unix / Linux distributions can install from souce. The sources are kept at the GNU XBoard home page.WinBoard / XBoard source codeXBoard 4.5.2 new Board Options menu dialog
