Hey, thanks for working on this. I have two thing that I am not sure about:

• The Makefile references https://hub.docker.com/r/juicedata/golang-cross when using make snapshot/make release. Where can I find the source code and pipeline for it and will it also be updated to 1.20?

• Is there a reason not to go to 1.21, which is the latest stable version?

[davies]

We prefer old stable (1.20) rather than the latest stable.

The image for release could be updated later.

When Go 1.22 is released in February the 1.21 will become the new oldstable.
