Eliot Miranda uploaded a new version of Cog to project VM Maker:
http://source.squeak.org/VMMaker/Cog-eem.417.mcz
==================== Summary ====================
Name: Cog-eem.417
Author: eem
Time: 28 October 2020, 10:59:05.398054 am
UUID: 34d31321-fc48-4fa5-a5f6-26d56a703a64
Ancestors: Cog-eem.416
And rename the opffsetBy: primitives suitably.
