change of URL structure

[danlaquarium]

Hi,

My entire container broke when you modified the directory structure by adding /refs/tags in the URL to fetch the v1.2.2-r1.tar.gz file.

If you could send a general advisory, I would really appreciate it lol :D Also you may name one file as master or stable, so that we may always rely on this official version for production environments.

Thanks for your awesome work and keep up the updates. I really appreciate the work you did.
