Why is the Macintosh version of Igor Pro 8 64-bit only? Will there be a 32-bit version?

Apple has announced that High Sierra (macOS 10.13) will be the "last macOS release to support 32-bit apps without compromise". Because of this, and the fact that the vast majority of our Igor Pro 7 Macintosh users are already using the 64-bit Igor application, we have dropped the 32-bit Macintosh application for Igor Pro 8. Unless you are using a 32-bit only XOP on Macintosh this change should not affect you.

On Windows, the Igor Pro 8 installer installs both 32-bit and 64-bit applications.
