Stable version 1.1.19 has been released.
The download page includes a JAR file you can directly run ("practice mode") to test out the new version without starting a server.
Version 1.1.19 contains these features and fixes:
New game option for house rule: Roll no 7s until a city is built
Trading port/harbor graphics updated
Reset board during initial placement: Pick randomly-selected robots, instead of keeping same robots
Check client password when "New game" is clicked, not later after filling out game options
For servers using an optional user database, new config options about creating or requiring accounts
For more details, please see the release notes.
Update 12/3: The full and source .tar.gz downloads have been updated to remove clutter files from OSX.
