A lot of you have been asking for us here, and we delivered.
For now you can get Wesnoth 1.10 for Windows. We hope to have Linux support very soon. There are also plans to put the development (beta) versions of Wesnoth on Desura.
This also means that you now have a method to download patches for Wesnoth; no more downloading the entire 300mb game every time there is a new release.
