Little Go Description
Little Go is a free and open source iOS application that lets you play the game of Go on the iPhone or iPad. You can play against another human (on the same device), or against the computer. The computer player is powered by the open source software library Fuego (http://fuego.sf.net/). The minimum requirement for running this version of Little Go is iOS 9.0.

Features:
- Board sizes between 7x7 and 19x19 (start a new game to change the board size)
- Let the computer player suggest a move or immediately play the move for you
- Calculate the score at any time during the game (area scoring is the default, territory scoring can be selected at the start of a new game)
- Adjust the computer's playing strength and resign behaviour by selecting from a number of presets, or by fine-tuning advanced settings
- Play even games, or games with 2-9 handicap stones (fixed stone placement)
- Select from 5 pre-defined rulesets when you start a new game, or adjust game rules to your preference (komi, ko rule, area/territory scoring system, number of passes to end game, resume play by alternating/non-alternating play, four passes end game)
- Place arbitrary black and white stones for initial board setup before a game starts
- View board positions for moves played earlier during the game (no support for game variations, though)
- Discard moves (aka "undo")
- Display move numbers and coordinate labels
- Zoom & scroll board
- Create and edit board and move annotations (e.g. good/bad move, good position for black/white, etc.) and add textual notes to a position
- Mark intersections on the board with symbols, markers and labels, and draw arrows or lines on the board
- Display player influence (aka territory statistics) for an estimate who owns an area
- Computer vs. computer game for entertainment
- Save & load games to/from the archive
- Use iTunes file sharing to transfer saved games to/from your iOS device
- Import/export game files from/to other apps on your device (e.g. Mail, DropBox)
- In-app user manual (text-only)
- Submit bug report email from inside the app (yes, this *is* a feature :-))
- For the technically inclined: Watch what happens behind the scenes when Little Go and Fuego talk to each other over the Go Text Protocol (GTP)

Your contribution in any form (coding, UI design, testing, bug reports, creating an app video preview, website design) is welcome - please contact me or visit the support website to find out more.

A note about the project state: Several years of development have gone into Little Go since its inception in January 2011. The app now has a feature set that is, I believe, quite nice :-) for a free program. My main focus therefore lies on fixing any remaining bugs (of which I am sure there are plenty) and keeping the app running under future versions of iOS.

Little Go 1.7.1 Update
2022-09-23
This is the Little Go bugfix release 1.7.1. It contains two fixes for bugs that caused the app to crash (#397 and #398).

The previous release was the Little Go feature release 1.7.0. An overview of the changes follows, for more details read the in-game Changelog.

Features
--------
- The app now supports reading and writing of all SGF node annotation and move annotation properties (#339). The app also displays these properties' values and lets you edit them. This means that you can now add a valuation to a move (e.g. good/bad move) and/or to the entire board position (e.g. good position for black/white), designate a board position to be a "hotspot" (e.g. it contains a game-deciding move), annotate a board position with an estimated score, and finally you can add textual notes to a board position. Annotation data is displayed by, and can be edited via, an all-new annotation view.
- The app now supports reading and writing of all SGF markup properties (#349). Except for the DD property (dim parts of the board), the app also displays these properties' values and lets you edit them. This means that you can now mark intersections on the board with 5 different symbols (circle, square, triangle, "X" mark, "selected" symbol), place single-character letter markers or single-digit number markers, place a free-form label text, and finally you can draw arrows or plain lines on the board. The app has an all-new markup editing mode for this (accessible via menu icon) that includes drag & drop support to move around existing markup.
- In the Settings screen there are now a number of user preferences that affect how markup is drawn and that let you tweak some aspects of the markup editing process.

Improvements and changes
------------------------
- The general user interface (UI) of Little Go now looks and behaves the same on all device types (#371). This unification of UI layouts became necessary because the effort to support different layouts proved to be too much. Also the unification provided the opportunity to get rid of many behind-the-scenes hacks. The main changes are: 1) Smaller iPhone devices which only support the Portrait orientation UI layout, now display board positions and the navigation buttons differently than before. 2) Larger iPhone devices now display a tab bar when in Landscape orientation (alas, reducing the size of the board). 3) iPad devices now always show board positions when in Portrait orientation, and when in Landscape orientation they display board positions and navigation buttons differently than before.
- Changed the icon of the "More Game Actions" button (#377). The previous icon was a "curved arrow" symbol, which seemed to confuse many users so that they couldn't find important actions, such as "New game". The new icon is the established "hamburger menu" icon, which should now more clearly indicate that the button pops up a menu with actions to select from.
- Button boxes and the board position list now support Dark mode by switching to a dark background color (#378 and #379). Thanks to Peter Waldispühl for reporting this.
- For more improvements/changes see the Changelog.

Bugfixes
--------
- Board position zero (representing the start of the game) sometimes did not display handicap and komi. This is now fixed (#374).
- Various speculative fixes for potential app crashes. See the Changelog for details.

Regressions
-----------
- A bug was introduced in version 1.6.0 that would cause Ko detection to fail after the app was suspended and was forced to restart by the operating system (a relatively common occurrence). This is now fixed (#372). Because Little Go has struggled with Ko detection many times in the past, this regression was particularly painful.

Technical changes

1.6.0 2021-02-27
This is the Little Go feature release 1.6.0. An overview of the changes follows, for more details read the in-game Changelog


Features
--------
- Added an SGF parser (#112). Among other things you can now see if an SGF file in the archive contains more than just one game (#338). A number of user preferences give you some control over how SGF files are processed (#337).
- Added a new user preference "Discard my last move" to the "Board position" settings screen (#99).
- Added a new entry to the "More game actions" menu that lets you play a rematch without showing the "New game" screen first (#313).
- Added a new user preference that lets you choose what kind of computer assistance you would like to receive. With this you can now tell the computer to only make a suggestion how to play instead of immediately making a move on your behalf (#28).

Improvements and changes
------------------------
- The buttons that let the user navigate between board positions have now more space between them (#346), making it less likely that the user taps the wrong button. Thanks to Dan Hassin for both reporting the issue and implementing the fix.
- Improved error handling when loading a game from the archive.
- When a game is saved to the archive the current player names are now written to the SGF data (#237).
- The user interface has been adapted to newer iOS devices with a sensor notch, rounded corners and/or a Home indicator instead of a Home button (#336).
- The app now supports Dark Mode (#345). A new, darker wooden background for the board still needs to be found (#360).
- When Little Go is newly installed from the App Store the default computer player is now weaker (#358). This should give more users a positive first app experience. Users who want a challenge can still increase the difficulty by switching to a stronger computer player. A side effect of this change is that the default computer player no longer uses the "Pondering" setting, which means that the iOS device's battery should now be used up a lot less.
- Added another predefined computer player that has "Pondering" disabled. Users who already have the app installed need to select "Reset to defaults" in the "Players" settings screen to see the new player.
- The app's user interface no longer exposes GTP engine profiles as a separate entity, instead the user interface now only displays players (#211).

Bugfixes
--------
- The app no longer crashes when a game with many moves (500 or more) is archived or unarchived (#357).
- The app no longer crashes when a game is loaded while an ended game with non-alternating dispute resolution is present (#361).
- Speculative fix for a potential app crash when an SGF file is imported (#362).
- The information which player resigned is no longer lost when the user switches to an earlier board position (#341).
- On iPhone devices with larger displays, when the device is rotated while the activity indicator is displayed in the status view the activity indicator is now still displayed after the rotation (#343).

Regressions
-----------
- All iPhones: When board setup mode was added in version 1.5.0 a bug was introduced that made it possible for board position lists to show erroneous information when moves were discarded and then replayed, or when games were restarted with different characteristics. This bug has now been fixed (#359).
- iPhone devices with smaller displays: When iOS 13 or newer was installed on these devices the current board position view stopped responding to taps. This bug has now been fixed (#344).

Technical changes

1.5.1 2011-12-23
This is the Little Go bugfix release 1.5.1. It contains a fix for a bug that causes the app to crash during launch on iOS 9.x and below (#332). Thanks to Li Chen Ke and Dennis for reporting the issue. The previous release was the Little Go feature release 1.5.0. It contains the following changes: Features -------- - Added a board setup mode (#276). When you start a new game, instead of beginning to play you can now switch to board setup mode. In this mode you can place black or white stones in any order and combination to set up the initial board before you begin to play moves. In addition to placing stones, you can select the side which is to play the first move. Read the "Board setup" section in the in-game manual for a detailed feature description. Bugfixes -------- - Fix for a memory leak in UnarchiveGameCommand (#331) Technical changes ----------------- - Added an initial set of a few automated UI tests (#134)
