I have been trying to install a module using `go get github.com/xxx/xxx`. It used to get installed easily previously, but the maintainers release a new release and it's not working for me anymore. I am looking to know if there is any way I can get the previous release to install? By default it is installing the master branch. Is there any flag where I can put the branch info like `go get github.com/xxx/xxx --branch=xxx`?
