Add changed content to notification when ticket is updated

Hello again :) !

I would like to include changed content into notification. When ticket is updated, users gets email with information that his ticket is updated, but I am not able to iclude what was added/removed/changed, etc...

Is there a way to add only changed content to the notification template so requester can see right in the notification what was changed ?

I know that requester can go to the history tab for particular ticket, but putting this into notification would be realy great.

It was the first thing that user asked me when we tested our notification from helpdesk - "I know that my ticket is updated, but what was changed" ?

Thanks in advance for advice!

Lukasz.
