Release Notes

Bug fix version of NyARToolkit/2.3.0

-NyARIdMarker problem -- NyARToolkit selects a different target marker when a few marker in a captured image.
-"new" keyword in main loop -- "new" keyword in main loop was deleted .
-The remainder of debug code. -- In NyARPickUp_O3, unnecessary debug code was deleted.
-Ticket:#17015,#16937

NyARToolkit/2.3.0のバグフィクス版です。

・NyARIdMarker認識で、複数のマーカ存在時に表示マーカの選択ミスが起こる問題の修正。
・認識ループ内に残っていたnewの削除
・ARマーカ認識のコードにデバック用のコードが混入していた問題への対処
・対象チケット:#17015,#16937
