Widelands Build 20 Released

The Widelands Development Team is proud to announce the immediate availability of Widelands Build 20.

Build 20 features a new tribe – the Frisians – as well as four new campaign scenarios and a new “Barracks” building for recruiting soldiers. Also, the AI has been rewritten to use a genetic algorithm. The user interface comes with new features that make it easier to use, like map zoom, dropdown menus, a new ships list, and improved keyboard navigation. Build 20 also continues the behind the scenes cleanup, polish and modernization that was started with Build 19.

Widelands is distributed for Windows (64-bit) and Mac OS X >= 10.7 (Intel, 64-bit) and in source code. We no longer ship binary Linux packages because of the poor compatibility between Linux distributions. Instead, we try to make compiling for Linux users as easy as possible. Also, most distributions will pick up Build 20 into their repositories very quickly. Both binary and source packages are available from our Download page.

If you like what you see, have a look around this site. You may also want to check the forums and our IRC channel, #widelands on Freenode, to arrange multiplayer games with other players.

We especially welcome every helping hand: help us find bugs, translate the game, add new scenarios or features! If you want to get even more involved in the further development of Widelands, you can meet us on the forum or subscribe to Releases are also announced to

wow ... no: double wow ... no: triple wow .... no: ....


This is really a great release. Thanks to all the developers!!!



Another nice new feature is the ingame-clock in the top left corner.

My other favourite new features might be: - hosting online matches right away - without port-forwarding - seeing which wares are on their way - the auto-speed command - improvements to production-sides' logic (including forester) - replays of collectors-matches and online-collectors-matches without crashes


Looks like those comments need support for lists and editing face-wink.png


Great! I can say only "wow" as kaputtnik!

Also great work with this summary, GunChleoc. That is very useful (much better than standard changelog).


Ladies & gentlemen who worked on Widelands, a few hours or (for some) many many days: congratulations! You should be proud of this fine release. Interesting things are already in the works toward build 21...


Awesome! Thanks for all the hard work!!!


Congratulations! What a fantastic release. Thanks for all your hard work!


Für mich ist die neue Version untauglich, da die Tastaturkürzel "," und "." (zum nächsten/vorherigen Bildschirm springen) gestrichen wurden. Das sind für mich die wichtigsten Tastatürkürzel überhaupt - wie könnt ihr begeisterten Build 20-User so zufrieden sein???

Frisen: häßliche Träger, langweilige und sehr identisch aussehende Gebäude die auch noch viel zu groß sind, häßliche Grenzmarkierungen usw.

Bin ich hier der einzig völlig enttäuschte User?

For me, the new version is disabled because the keyboard shortcuts "," and "." (to the next / previous screen jump) have been deleted. These are the most important keyboard shortcuts for me at all - how can your enthusiastic Build 20-user be so happy ??? Frisians: Ugly carriers, boring and very identical-looking buildings that are too big, ugly landmarks, etc. Am I the only completely disappointed user here?


I'm also wondering why "." and "," are removed and suggest to reinstall that. It doesn't bother me because I've not used that that often, but a feature without disadvantages should not be removed...


You say it is impossible to load old gamesaves from build 19. Is there no posiibility to convert the save files or something else?


I don't know, but I would probably know it. So this would still have to be arranged. By the way, this is probably no good place for quick feedback anymore... Just saying.
