Tagging a Go Package Makes It Stick Forever, Using the Proxy

Fleeting

As soon as someone downloads you golang go, it gets downloaded in https://proxy.golang.org/. Further attempts at downloading it will get it from proxy.golang.org

If you decide to move the tag, people that will use it will still have the old version, unless they specify not to use the proxy (export GOPROXY=direct).

Therefore, note to myself: NEVER RENAME A TAG IN A GO PACKAGE. That is a general wisdom, but in particular in that case it is very annoying.
