q5go 2.1.3

This is a minor update. The two most visible changes are an added autoplay feature for viewing SGF files, and more support for KataGo's ruleset feature.

q5go 2.1.2

This is a bugfix release to fix an issue when saving SGF files in locales where a comma is used instead of a decimal point.

q5go 2.1.1

This is a minor update to version 2.1 to also allow the maximum board size in AI vs AI play.

q5go 2.1

This is primarily a relatively small bugfix release. These are the major user-visible changes in 2.1:

• A number of crashes in odd situations were fixed (such as analyzing games with komi values like 650, or handling invalid server messages).
• It is now possible to copy/paste positions in Edit mode.
• The batch analysis dialog has a new button to enqueue an entire directory of SGF files.
• Engine games now allow board sizes up to 52.

q5go 2.0

These are the major user-visible changes in 2.0:

• Pattern search is now available, similar to Kombilo. Use the settings dialog to create a suitable database. Unfortunately existing Kombilo databases can't be used for this because of 32/64 bit compatibility issues.
• Database load times are reduced, and threading was added so that the user interface remains responsive.
• Multiple online games can now be observed in a single window with clickable previews to switch between them. The old mode of one game per window is still available.
• There is a new "Tip of the day" dialog on startup, which displays features that are maybe not easily discoverable. It can be disabled.
• There are several new high resolution wood textures for the board to choose from.
• When playing engines that are capable of analysis, the evaluation is now collected during the game and can be displayed live.
• Engine configuration now allows engines to be unrestricted in board size and komi, catching up with improvements in KataGo over Leela Zero.
• Some GTP bugs were fixed, which may improve compatibility with certain engines.
• Window titles can now be overriden in the settings, which should help with streaming setups.
• Performance improvements for the screen updates should now make it feasible to turn off quiet mode when online, which allows the server to send live player and game updates.
• There is a new option to highlight the user's own chat messages in a different color.

q5go 1.1.1

Version 1.1.1 is mostly a bug-fix release to properly suppert saving and loading large board sizes. But there are also a few additions:

• There is now a tool to manage and remove the information added by engine analysis from a given SGF file.
• It is now possible to save all variations in a file into separate files.
• It is possible to choose a path for autosaving online games.

q5go 1.1

These are the major user-visible changes in 1.1:

• Performance improvements when loading and editing very large SGF files.
• q5go can now detect when an observed game on IGS is adjourned and restarted and follow it in the same window. This requires the server to be set to non-quiet mode.
• When playing an engine, there is now a "Play again" button.
• In an online match with Canadian time, time warnings can now be enabled for remaining average time, not just remaining total time.
• In an online match, remaining seconds in low time situations can now be shown on the opponent's last placed stone.
• Added a "Go terminology" SGF to the tutorials.
• The greeter window now has a hint to choose "Play online" for a full set of menus.
• The program is more helpful when detecting a broken SGF written by Jago.
• Added more helpful error messages when editing servers in the preferences.
• Score evaluations are now shown in the board window when analysis is on.
• Added a feature to visualize connected stones by drawing thick lines between them. May be helpful for beginners.
• GTP support was extended to support board sizes > 25, for KataGo.

q5go 1.0

These are the major user-visible changes in 1.0:

• A greeter dialog was added, similar to the ones used by cgoban or gGo.
• There is now a "Learn Go" button that brings up beginner tutorials in a slideshow view.
• Engine configuration in the preferences is a little more friendly.
• Edit mode works differently. Depending on the situation, an edited position can be appended to or inserted before the current node, or replace a previous edit.
• The board window now has menu items for undo/redo.
• When playing on IGS, the comments box now allows chatting even after a match has completed, making it unnecessary to find the opponent's talk tab.
• Corrected a bug when parsing nmatch preferences on IGS.

q5go 0.9

These are the major user-visible changes in 0.9:

• Support for KataGo analysis. The evaluation graph can be switched between score and win rate.
• A new option to start a game against an engine game from the current board position.
• A new AI vs AI play mode. The number of games to be played is configurable, and an opening book can be used.
• It is now possible to hide/show the analysis markup of the board rather than having it displayed at all times.
• The variant game dialog now supports removing intersections from the board, allowing new variations of the game.
• Several bug fixes related to scoring mode when playing games on IGS.
• There are now a few presets for the stone visual appearance to make it quicker and easier to arrive at a nice look. The darkness of the shadows can now also be configured.
• Sounds should be a little more reliable, the samples used for stones were too short to be played on some systems.

q5go 0.8.1

This is a minor update for compatibility with the latest release of Leela Zero (0.17).
