Code view could be enabled from the Issues tab on release or version details screen.

If the Code view enabled the user can’t configure columns anymore. The columns set is predefined.
In the code changes column the user can see:
Number of branches which are created for a particular Jira issue
Quantity of commits
Amount of pull requests and their statuses
In case more than one page of issues lists are available, sorting by Code change column will only work for the current page and will not take data from other pages, in contrast to sorting by any other column in the table.
Such limitation is dictated by technical aspects of code changes data fetching.
After a click at branches, commits or pull requests a user can see a screen with detailed information about each entity:
User can navigate from the details screen to the repository to check the details like changes in the code, code review, etc
Information about builds and environment will not be available in the current version of the release management.
