-which removed some undocumented features related to pull requests.
-
-. With Bitbucket Server 7.x, Jenkins Pipeline jobs can no longer perform a lightweight checkout of the `Jenkinsfile` if you are using the merge strategy for builds.
-.. This is due to Bitbucket Server 7.x no longer storing the merge commit for PRs to `refs/pull-requests/*/merge` which was a prerequisite for lightweight checkout.
-.. Bitbucket Server Pipeline jobs will automatically fall back to heavyweight checkout.

-has explained their reasons for making this change] and has made it clear they will not be re-adding this behavior.
-. For Jenkins Pipeline jobs to function for pull requests on Bitbucket Data Center 8.x and above, you need to enable "Call Changes api" option in the plugin configuration.
-.. Since Bitbucket Server 7.x no longer automatically creates the required refs for pull requests. Calls to this new API are required to trigger ref creation.
