There is no stable 64-bit release for 68.12.3 or any higher version!

It's taking insufferably long time to come with the version that is already outdated before it comes out. I'm not a developer, so I can only imagine what a tedious and hard work it is! I suggest that you will set up a donations link - I will be more than happy to donate developers of MyPal because you are my heroes, and I really value your work!
