"key" json parameters removed

[maxdd]

Is there a reason why the "key" json field has been removed from the api?

 for wl in worklogs:
        if wl['author']['accountId'] == tempo_user:
              issue_key = wl['issue']['key']

Is it possible to restore it back?

In the mean time my solution is to pass through jira

issue_key = jira.issue(wl['issue']['id']).key
