Why don't I find warning tab not there on Project -> Releases page on Jira Server 7.10?

[vivekgupta_hsc]

I have Jira server 7.10.0. I have linked it with Bitbucket server. I don't find warning tab not there on Project -> Releases page. Is it not supported in Jira server?

Am I missing any configuration or Is warning setting need to enabled (if yes then how)?
