Hi all
I have been using ConTeXt (X86 64bits) on my mac mini Apple Silicon M1
and it works well using Rosetta translation for the M1. I recently
installed the ARM 64bits version (separately from the X86 64bits
version) which I assume does not require translation using Rosetta.
However I had a error with the lmt_shade command in the ARM 64bits
ConTeXt verson but not in with the X86 64bits version of ConTeXt. The
MWE is shown below. This is actually taken from the LuaMetaFun manual. I
also noticed that some figures are missing in the manual (Chapter 7,
Shade) which is part of the ARM 64bit tree but not in the manual in the
X86 64bits tree.
Best Wishes
