The quality of many textures has been dramatically improved, some visual components have been added to decorate the game board, and the black coins have been replaced with blue ones to make it easier to see those coins against the background. Also, the latest version benefits from some engine bug fixes, and has been compiled for 64-bit Windows instead of 32-bit. Older builds should still work with the server, so if your device doesn’t support the X86-64 architecture then you can get away with the most recent X86 build to play with other people, even though it is now outdated.
