Hi! We recently started using the Readium cli and ts-toolkit in Storyteller, and it's been working very nicely!

One issue we have seen users reporting is that they cannot run the readium cli on older devices, throwing this error

This program can only be run on AMD64 processors with v3 microarchitecture support.

This seems to be due to v3 being the lowest support version set here

My question: is this a strict requirement for readium to operate? If it would be at all possible to use v2 instead, many more of our users would be able to continue to self-host.

From my very limited testing (serving both media files and manifests) I don't notice any particular difference between a version compiled with GOAMD64=v2 and GOAMD64=v3, but that does not mean one doesn't exist of course.
