What's new?
  • Dropped support for old GNU/Linux distributions.
  • All processor architectures are supported again.
  • Added detection for all draw conditions:
  • threefold repetition
  • insufficient material
  • fifty-move rule
  • stalemate was already detected
  • Added undo and redo.
  • Added options to change piece colors.
  • Added an option to make knights face sideways.
  • Added support for the XBoard protocol commands "?", "undo" and "remove".
  • Now changed settings are applied instantly even when the engine is thinking.
  • Now the status labels indicate if the game has ended and the reason, if any.
  • Now the engine can use results from partial searches.
  • Significantly improved engine performance.
  • Improved exit time when the engine is thinking.
  • Added repaints to fix some cases where nothing seems to happen until you move the mouse.
  • In XBoard mode, now Project Invincible stops thinking when it receives the command "new", "force", "white", "black" or "result".
  • Improved responsiveness in XBoard mode when a process with higher priority has high CPU usage.
  • When the engine finds that it can be mated no matter what, now it makes the move that leads to the slowest mate. Previously it made a random legal move.
  • Improved startup time in XBoard mode.
  • In XBoard mode, now Project Invincible rejects clearly invalid positions.
  • Fixed a deadlock when changing the number of threads when the engine is thinking.
  • Fixed: the process didn't terminate if you attempted to exit the game when the game showed a dialog that asked something.
  • Fixed an use-after-free on exit if a dialog that asks something has been shown.
  • Fixed theoretical race conditions.
  • Fixed minor memory leaks.
  • Windows: fixed crash on exit with QeffectsGL.
  • Unix: fixed an error message on exit with the closed source "fglrx" AMD graphics drivers.
  • Unix: improved performance by enabling more compiler optimizations.
  • Unix: made the binary smaller by stripping information that you don't need to run Project Invincible.
  • Unix: when Project Invincible is installed, now it stores its settings in $XDG_CONFIG_HOME or $HOME/.config as required by the XDG Base Directory Specification.
  • Minor changes.

@Magibon: version 2.00 has mouse controls. :)

i like the simplistic design, and small footprint.
i love the chess pieces and how you're able to move the board's perspective.

only downside, and it's quite important for me:
- can't use the mouse to move the pieces :(

being forced to use the keyboard to move the pieces takes away from the experience.

As for the AI, it's perfect.
It's not too strong, where every move you make backfires.
This feels natural, where you're not thinking: "ahh man.. of course.. it's a computer".

What sold me is "Stealth" :)

keeper... but i hope the dev. adds the option to use the mouse in future releases.
