Nightly builds for Linux, Windows and MACNightly builds are built automatically every day from the files in the Simutrans repository as they are. Builds for Linux, MS-Windows and Mac are available but still a compatible pakset is required.
They
may contain changes which make your savegames unreadable by any official version, or bugs that will destroy your game, or not even run. They are for bug testing only.
