Little Go 0.12.0 released

Posted on: Sun, 15 Sep 2013 22:18 By: patrick

Little Go 0.12.0 has been released to the App Store a couple of days ago. Since I plan to slow down my development activities on the project soon, the overall focus of the release was on improving the usability of Little Go, and less on adding cool new features.

The GitHub issue tracker has a list of all issues that I worked on for 0.12.0, and here is an excerpt of the changelog for the most notable changes:

  • It is now possible to configure the computer player with a threshold how quickly it will resign a game (#133). For instance, it is now possible to tell the computer player to never resign so that the game can be played out to the very end. This also allows beginners to play with a large handicap on a small board (up until now the computer player would always resign immediately when faced with an overwhelming handicap).
  • When an old board position is viewed, the intersection where the next stone will be placed is now marked with the letter "A" (#101). This can be disabled in the "Board position" settings.
  • Changes to the active profile are now immediately applied to the GTP engine (#123). For instance, it is now possible to change the playing strength or the resign behaviour of the computer player without starting a new game.
  • The user interface for changing the dangerous "Max. memory" profile setting is now vastly improved (#153). The maximum value that can be selected for the setting is now limited to a fraction of the device's physical memory, and the amount of physical memory that the device has is also displayed.

Finally, the GTP engine is configured to no longer recognize positional superko (#171). This is a temporary solution to bring the GTP engine's rules into sync with Little Go's rules. Little Go currently does not recognize superko, so this sync'ing fixes the problem that Little Go lets the user make a superko move which is then rejected by the GTP engine. Many thanks to Brid Griffin for emailing me a bug report that helped me with diagnosing this problem! Note that Little Go will officially support superko in 1.0.
