How to check the version of GitLab?

Question

How to check which version of GitLab is installed on the server?

I am about version specified in GitLab changelog:
https://gitlab.com/gitlab-org/gitlab-foss/b

Answer 1

I have Version: 12.2.0-ee and I tried the URL via (https://yourgitlab/help ) but I have not got this information. In the other hand I got this with gitlab-rake with success into the command line:

sudo gitlab-rake gitlab:env:info

... GitLab information Version: 12.2.0-ee ...
