How to find all JIRA issues that was merged to a specific branch?

[Piotr Soróbka]

Hi,

so we are using release branches. In a point of time, we create a release branch from master branch, and work on stabilizing the release.

I would like to know, which JIRA issues were merged to this release branch. Currently, I can see that the PR related to an issue was "Merged", but I don't know to which branch. 

Is it possible?

Hi,

To make sure what you are asking.

Do you want to find all issues merged to a branch in a specific 1 pull request?
