# Merge requests versions

> Will be [introduced][ce-5467] in GitLab 8.12.

Every time you push to a branch that is tied to a merge request, a new version
of merge request diff is created. When you visit a merge request that contains
more than one pushes, you can select and compare the versions of those merge
request diffs.

By default, the latest version of changes is shown. However, you
can select an older one from version dropdown.

You can also compare the merge request version with older one to see what is
changed since then.

Please note that comments are disabled while viewing outdated merge versions
or comparing to versions other than base.

>**Note:**
Merge request versions are based on push not on commit. So, if you pushed 5
commits in a single push, it will be a single option in the dropdown. If you
pushed 5 times, that will count for 5 options.
