Project 'gitlab-org/prometheus-client-mmap' was moved to 'gitlab-org/ruby/gems/prometheus-client-mmap'. Please update any links and bookmarks that may still have the old path.
Taint checking has been deprecated starting Ruby 2.7: https://bugs.ruby-lang.org/issues/16131. It is well described, for example, here: https://blog.saeloun.com/2020/02/18/ruby-2-7-access-and-setting-of-safe-warned-will-become-global-variable.html
As a result, we receive warnings in our CI when running Ruby 3 builds, e.g.: https://gitlab.com/gitlab-org/gitlab/-/jobs/1524901589#L409
