**As** a user watching the activity
**I want to** see only an indication of custom fields of type long text 
**so that** the activity is cleaner when doing many changes in those custom fields.

**Acceptance criteria**

In the activity tab:

* Display updates to long text custom fields in the same format as description updates (diff view):

* Created

* **{Long text field name}** set ([Details](https://community.openproject.org/#))

* Updated:

* **{Long text field name}** changed ([Details](https://community.openproject.org/#)) Begin of the insertion

* Clicking on the "Details" link will take the user to the diff view also used for e.g work package description and project status explanation

* Applies to all customized objects currently displaying history/activity:

* WorkPackages

* Project 


End of the insertion Begin of the deletion


End of the deletion **Visuals**

_"Remarks" is a custom field:_

<img class="image_resized op-uc-image op-uc-image_inline" style="width:408px;" src="/api/v3/attachments/105632/content">
