0.9.2: Bugfix release

Summary

Version 0.9.2 is a bugfix release. It was published on the App Store on January 04 2013. It contains only the changes listed below.

Bugfixes

• Fix for crash if Play tab is not visible and low memory conditions occur (issue #86)
• Fix for crash if an error occurs while loading an archived game, e.g. because the game contains an illegal move (issue #88)
• Fix for crash when Little Go thinks that a move made by the computer player is illegal. Note that the root cause of the problem has not yet been identified, but at least the app no longer crashes when the condition occurs. Instead you will be asked to submit a bug report (please do!), the game in progress is automatically saved to the archive and a new game is started to bring the app back into a stable state. This temporary solution will remain in place until I can track down and fix the actual bug (issue #90).
• Fix for memory leak that occurs when the Game Info view has been selected on the Play tab, but the Play tab is not visible and low memory conditions occur (issue #87)
• Fix for memory leak when a bug report is sent (issue #91)
• Fix for GUI update errors on Play tab after an error occurs while loading a game (issue #89)

0.9.1: Bugfix release

Summary

Version 0.9.1 is a bugfix release. It was published on the App Store on December 15 2012. It contains only the single change listed below.

Note that starting with this version the project's bugtracker is now hosted on GitHub

Bugfixes

• Another bug in the Ko detection logic is now fixed (#2). For instance the following sequence: Black A2, White B2, Black pass, White C1, Black pass, White A1. If Black now tries to capture on B1, this was erroneously thought to be illegal due to Ko.

0.9.0: Feature release

Summary

Version 0.9.0 is a feature release. It was published on the App Store on December 06 2012.

Below is a summary of changes, taken verbatim from the ChangeLog document.

Features

• 3 new settings have been added to profiles (maximum number of playout games, maximum thinking time, ponder time). These settings provide much improved control over the computer player's playing strength.
• Individual profile settings are now hidden in an "Advanced configuration" screen. The user can still tweak those settings if she wants to, but there is also a simplified "playing strength" screen where, by selecting a playing strength, the user adjusts several profile settings in a single action, without having to know the technical details behind each setting.
• The computer player can now be interrupted when it is thinking.
• The user can now choose to send a crash report if the app crashes (available when the app is launched the next time after the crash). Settings are available on the "Diagnostics" tab. Read the in-game manual for more information.
• The user can now send send a bug report email with attached diagnostics information file from within the app. The function is available on the "Diagnostics" tab. Read the in-game manual for more information.
• The Game Info view now displays the currently active profile.

Bugfixes

• Loading an .sgf file with bad content no longer crashes the app. Thanks to Andrew Hersee for reporting this bug.
• iPhone only: The Status line is now 2 lines high and no longer truncates texts. Thanks to Andrew Hersee for reporting this bug.
• Improved protection against data loss after a crash (preferences data is saved more often, and the game in progress is saved after every move). Thanks to Tripp Lilley for reporting this bug.
• It is no longer possible to enter empty profile and player names
• iPad only: The Go board is now properly resized when the interface orientation changes while the "Play" tab is not visible
• Display an error message when an illegal save game name is entered (instead of just silently not saving the game)

Technical changes

• The project's source code is now hosted on GitHub (https://github.com/herzbube/littlego/)
• The project now has a Trello board where you can see what is currently being worked on (https://trello.com/board/little-go/4fd84c295027333d460dcc32)
• An Ohloh page now provides mildly interesting source code statistics (https://www.ohloh.net/p/littlego)

0.8.1: Bugfix release

Summary

Version 0.8.1 is a bugfix release. It was published on the App Store on June 21 2012.

Below is a summary of changes, taken verbatim from the ChangeLog document.

Features

• New application icon
• Added "Quick Start Guide" section to in-game help

Bugfixes

• A bug in a low-level function, which has been present in all versions of Little Go since its initial App Store release, has finally been found and exterminated. The bug caused "Undo" to not work correctly in certain situations. The error, when it manifested, did not have an immediate visible impact in the GUI, instead it caused all sorts of follow-up problems to occur (capturing stones might not work, suicide moves might be allowed, marking dead stones in scoring mode might not work correctly, and in some extreme cases it might even cause the app to crash).

0.8.0: Feature release

Summary

Version 0.8.0 is a feature release. It was published on the App Store on April 24 2012.

Below is a summary of changes, taken verbatim from the ChangeLog document.

• iPhone now supports upside-down portrait orientation
• Improved in-game help

Bugfixes

• Loading a game is now much faster
• Drawing, especially while moving a stone around the board, now uses 10-15% less CPU power, which improves battery life
• Ko is no longer erroneously detected in certain situations (e.g. black has stones on A2, B1, B3, C1, C3, white has stones on B2 and C2; black now plays on D2, white on B2; in this situation, black C2 was erroneously thought to be illegal due to Ko)
• Profiles: "Reuse subtree" is now always enabled (and cannot be disabled) when pondering is enabled; previously the two settings were independent of each other, which was a bug
• Loading archived game now works even if temporary file is still around for some reason

Technical changes

• Rewrite of Play view drawing code
• Lots of new unit tests
• Upgrade to iOS SDK 5.1
