Freeciv-3.0 supports also second kind of installer build environment, referred as installer_cross or Crosser-based installers. The benefit of this installer environment compared to official msys2 one is that it's much easier for us to do snapshot builds with it. So easy, that we automatically get nightly builds here: http://files.freeciv.org/packages/windo ... htly/S3_0/
If you want all the latest bugfixes, these nightly installers are the ones to use. The biggest known issue with installer_cross installers at the moment is that Native Language Support does not work for Qt-client.
Crosser used by freeciv was yesterday update to version 2.1. Assuming everything works, the new builds coming out this night will contain the updated environment (dependency dlls etc).
