This feature needs to be documented, so here is the documentation

GitLab has model-level support for the idea of one merge request
"blocking" another from being merged - the second MR can only be merged
once the first one has, itself, been merged. We also show any existing
blocks in the merge request widget.

This commit adds support for adding and removing these blocks when
creating or editing a merge request.

This pagination is not used anywhere so there is no reason
to keep it. It seems the usage of offset_id was probably
removed in 90c60138

The merge train could not automatically merge CE into EE due to a
changelog file being removed in CE while it was modified in EE. To
resolve this, we removed the changelog file from EE as well.
