Giataly and gitlab-ce images have different versioning systems

I found that on the we have the gitlab-ce/ee images with tags like: 13.12.2-ce.0, 13.12.1-ce.0 and so on… But for gitlay I found only 13-12-stable tag and nothing else here: Is the an official repository? How can I get the gitaly 13.12.1 release?
Thank you.
