Bugfix Release 1.2.2

There is an update 1.2.2 available, which fixes two nasty bugs. A few new features (mostly user requests) have been added, too.

ChessxX 1.2.0 "Typewriter"

A new installation 1.2.0 is available. The new version has been polished at several places: Undo/Redo, Polyglot book handling, danish and italian translation, asynchronous searching, entering moves via keyboard (thus the name).
I hope, you enjoy our latest achievements.
Note:Mac Installation is updated.

ChessX 1.1.0 "Bookmaster" released

ChessX 1.1.0 has been released. As engines now can display book information and the opening tree can use any open database as reference, the name "Bookmaster" was chosen. But there are a lot of changes and bugfixes, so please enjoy our latest release.

ChessX 1.0.0 "Beetle" released

With a lot of new features (toolbars, symbolic notation, ECO and tournament view, merging of games,...) we proudly present ChessX 1.0.0
There are optimized Windows 7 builds (64 and 32 bit) as well as version for Windows XP and (of course) Mac OS X including Mavericks.

Sourceforge reforged

Sourceforge has updated their web infrastructure, thus subversion repositories and web links need to be updated.
SVN users will get an informational notice when updating.

Updated Installers

The Windows Installer has been updated due to a missing DLL.
Also published: a tarball for Unix Users!

New Version 0.9.6 "Instructor"

Our latest release features quite a few new features like the training mode, where moves are hidden and its up to you to find the correct continuation. Ideal for tactics training. Have fun!

Why Rudolph?

Well, to honor Michal of course?! Or could there be something else? Take a quick look into version 0.9.4, the next release will not present Rudolph anymore...

ChessX 0.9.4 "Rudolph" published

Right before christmas we would like to share version 0.9.4 "Rudolph" with you. There has been some internal reworking which allows us now to serialize index data of large databases. This accelerates reloading of indexed PGN files by factor 5. We hope you enjoy this and all other new features.

Why "Brazilwood"?

Brazilwood is one of the new board themes from James Coons that comes with the latest version 0.9.2.
As of 0.9.2, I would like to name each new release after some prominent new feature, so send in your ideas or your new code and make it to the "headline".
