XuanXuanGo 7.6 (8.51M)

XuanXuanGo7.6 update (949K)

1 Significant improvements of score estimator. Now XuanXuanGo can recognize "Semedori", or "forced capture". New version can also recognize weak points. All red-marked points in following figure can only be recognized by XuanXuanGo 7.6, these points cannot form territory and must be fixed. If the board status is as following, after you press "Score Estimator" button, for some reason, the left 4 white stones are not judged as dead, but XuanXuanGo let user manually change the stone's status, so you just need to click the 4 white stones to mark them as dead. These 4 stones are causing "Semedori"

2. Better color mode for entire program, it looks better
3. Added Ctrl-Up/Ctrl-Down short-cut key to go prev/next step while reading a game record
4. IGS: added friend functions
5. IGS: added viewing of saved games, it's useful if you lose network connection while playing a game and reconnect on it
6. IGS: add sending and viewing offline messages
7. Auto check if update available on official XuanXuanGo site
8. Bug fixes, the program is more stable

About IGS' friend function
If you play games on IGS for a period of time, you may interest in some players on it. You can add them as friend(or put them in black list, too). The server will notify you when they logon or play games. You don't need to be agreed by the players you want to add as friends.

I think no new functions need to be add for IGS after XuanXuanGo 7.6

New features or improvements in XuanXuanGo 4.0

3. Improved the game tab area.
4. The icons of toolbar buttons will show in corresponding dropdown menus.
5. Put some toolbar buttons into dropdown-style buttons to save toolbar space for the future versions.

System improvements:
1. Optimized starting process so that the program will start faster. The program window will restore to the size and position when it quits last time.
2. Added "Open Containing Folder" for game files.
3. When double-click game files in a Windows folder, instead of firing up a new instance of the program, the running instance will open the files.
4. For life-and-death editing, 'Pass' moves are used as wildcard moves for unexpected move. In the old version, only one move after 'Pass' move will be used to response, while in new version, the program will use unlimited number of moves after 'Pass' move to response.
5. Removed bugs found.

Game reading and editing enhancements:
1. Added 2 move properties:
a. Hide previous move numbers with exception. Let's assume that you are at move 30, if you set "Hide previous move" for it in the Move Properties dialog, move number 1 - 29 will not be shown; if you set the hiding exception as 2, only move number 1 - 27 will be hidden. Hiding previous move number will enhance the game's readability.
b. Show coordination for a certain move. When we navigate to the move, the game coordination will be shown, no matter if "Show Coordination" global option is opened or not.

2. Added 3 global options
a. Show Move Number for newly opened game files.
b. Show Coordination for newly opened game files.
