Yes, we still plan to do VFX Forth 64 for both Linux and Apple Silicon. I love my M1 box!
However, I foolishly took on a development contract that got bigger over time, but is now finished. That was the one that is reducing alt-coin mining power consumption by a factor of ten or so. At present, we are adding a few tweaks to the cross compiler by customer demand. Then there's some corporate stuff to do. After that it's ARM64 time. The first two targets are Linux and Apple Silicon. The order will depend on the quality of the debug tools and people's willingness to buy licences.
