Send message on mail if user-picker field was changed.

[Serj Shcherbakov]

Hi!
Can somebody share experience?

Any scripts/listeners?

I need to send custom mail every time when custom field is changed.
How i can make it? 

Thanks.

Each change on a JIRA issue triggers an "IssueUpdatedEvent" on which you can create "Event Listeners" to do something you need (like here, sending a custom email).
