Automation. Insert past field value into comment

[Evgeniy S_]

Dear community, hello.
Sorry if the question was, did not notice.

Please tell me how to solve the problem:
When changing the "Description" field, you need to:
- Comment on the task that the description has been changed.
- In the comments, indicate what's new has been added to the description.

I created a comment rule, but I can't display the old value of the field there, which was before the change.

The ideal option for me is to display in the comment the difference between the old description and the new one.
If this is not possible, please suggest how I can display the old value of the field in the comment.

Hi @Evgeniy S_ , 

you can use the following: 

Value before edit:  {{#changelog.description}} {{fromString}} {{/}}

Value after the edit:{{#changelog.description}} {{toString}} {{/}}

Showing a diff between the two is not a built in feature however.

Hi Evgeniy S_

You should be able to accomplish this by using the ChangeLog smart value field. Documentation here:
