**As** a user
**I want to** see at least one high-level reason of why notification has been sent
**so that** I can evaluate the importance of a notification.

**Acceptance criteria**

* The author is shown as a link with the name (instead of the avatar).
* The reason of the notification is shown in an abbreviated form
* The full list of what to render on every changed is Begin of the insertionbelow in the &quot;Update Strings&quot; sectionsEnd of the insertion Begin of the deletion to be provided by <mention class="mention" data-id="72513" data-type="user" data-text="@Parimal Satyal">@Parimal Satyal</mention>End of the deletion
* Preliminary ideas:
* The preview is structured like:
* **Status** changed from New to **Closed** 1 hour ago by [Niels Lindenthal](https://community.openproject.org/www.openproject.org) and 2 other updates.
* For long texts and comments the diff is not shown.
* **Comment** added 1 hour ago by [Niels Lindenthal](https://community.openproject.org/www.openproject.org) and 2 other updates.
* **Description** changed 1 hour ago by [Niels Lindenthal](https://community.openproject.org/www.openproject.org) and 2 other updates.
* **Subject** changed 1 hour ago by [Niels Lindenthal](https://community.openproject.org/www.openproject.org) and 2 other updates.
* The sorting is Begin of the insertiondone, withinEnd of the insertion Begin of the deletion done by the following priorities:
* WithinEnd of the deletion an aggregated journal Begin of the insertionentry,End of the insertion Begin of the deletion entryEnd of the deletion by the following priority: Begin of the insertion

* The list of reasons to display is a closed set of events that the user has chosen to be notified about in their user settings. For any work package item in Notification Center, the list of reasons must ignore the reasons from the above priority list that do not interest the user.End of the insertion
* Begin of the insertionThis means a lower-priority reason might actually be displayed instead of a higher priority one, if the user did not choose to be notified of that higher priority event. _Eg. if the user is has enabled notifications for &quot;all date changes&quot; and the work package has since also had a status change, the reason for notification remains the change of date. This is because the list of reasons is limited (for that work package, depending on settings) to the list of subscribed reasons for being notified._
* End of the insertion If the Begin of the insertionwork package is watched, all events are reasons for notification, so the entire list should be considered.
* These settings must take project-level settings into accountl; _eg. a work package in project A might have a different set of reasons forEnd of the insertion notification Begin of the insertionas project B._
* If the notificationEnd of the insertion row aggregates multiple notifications, the change highest up in above&#39;s priority list is Begin of the insertionchosen. 
* End of the insertion Begin of the deletion chosen.End of the deletion If two notification changes are tie for the same priority, the youngest one is Begin of the insertionused. 
* End of the insertion Begin of the deletion used.End of the deletion The notification within the aggregated row from which the change is highlighted determine the user name and timestamp of the notification.
Begin of the insertion_E.g.End of the insertion Begin of the deletion E.g.End of the deletion in a notification row that aggregates a version being changed one hour ago by user A and a comment with a mention two hours ago by user B, the change will display a comment with a mention was done two hours ago by user Begin of the insertionB._End of the insertion Begin of the deletion B.End of the deletion
* The importance of journal changes is also applied to the Begin of the insertionaggreggated list of changes in theEnd of the insertion activity Begin of the insertiontab. 
_Eg.End of the insertion Begin of the deletion tab. e.g.End of the deletion &quot;Assigned to&quot; is always rendered before &quot;Parent Begin of the insertionchanged&quot;_

**Update Strings**

_Notes_

* Brevity is prioritised so additional information is only provided where judged critical
* {time} is expressed relatively, as in &quot;3 hours ago&quot;
* {user} is expressed as a link
* The **parts in bold** are meant to really be in bold 
* I&#39;ve not included the &quot;and {n} other updates&quot; in these examples, but they would be present where relevant
* We need to produce a similar list for other languages (what is the localisation process?)
