Headings changed in commit 0c26733f:

  "Compatibility with GitLab versions"
  -> Had been renamed to "GitLab Runner versions".

  "Requirements"
  -> Had been removed. Similar content can now be found behind the links
     at "Features" and "Install GitLab Runner", so this redundant
     section has been removed.

  "Using GitLab Runner"
  -> Had been removed, contained two links to "commands" and
     "best practice".

Headings changed in commit 200f63c2:

  "Advanced Configuration"
  -> Had been put into a separate file and the section had later been
     removed from index.md.
