You can create one with:
```
bin/changelog -m %<mr_iid>s "%<mr_title>s"
```
2019-12-04 20:38:33 +05:30
If you want to create a changelog entry for GitLab EE, run the following instead:
```
bin/changelog --ee -m %<mr_iid>s "%<mr_title>s"
```
Note: Merge requests with %<labels>s do not trigger this check.
