go.sum is missing from the repository

[williamh]

Hi,

The go.sum file is needed when using go modules because it makes sure users build your program with the same modules you used. See this link for the rationale.

https://github.com/golang/go/wiki/Modules#how-to-prepare-for-a-release

Here are the steps to fix this. I can submit a pr if you want, but I thought it better to describe the steps in this situation.

1. revert 4407ba1
2. run go mod tidy
3. commit go.sum to the repository.

Can you please make a new release with this fix as soon as possible?

Thanks for your time,

William
