LUY 7.3.0

November 2021

LUY 7.3.0 is a major release and includes the following new features and improvements:

1. New features 

1.1 Global filter

Instead of the former "personal global filter", now a "global filter" allows filtering all of a user's data in LUY according to individual filter criteria. This may help to reduce the amount of data displayed and loaded in LUY and allow for better focus. A global filter applies to all pages, e.g., diagrams, lists, surveys, single element view. 

  • One or multiple global filters can be created, viewed, edited, shared and deleted via a new global filter page in the administration.

  • Global filters can be (de)activated via a global filter icon in the header menu.

  • While a global filter is activated by a user, the corresponding data elements will be hidden for that user in LUY. Other users without an activated global filter will still see all these data elements.

  • There are now two functional permissions for the usage of the global filter:

    1. Use global filters: Users with this permission can (de)activate existing global filters for their individual LUY account. Only users with this permission will see the global filter icon in the header menu.  

    2. Configure global filters: Users with this permission can configure, edit, share and delete one or multiple global filters via a separate page in the administration. Only users with this permission will see the global filter page in the administration.

  • Sharing allows to provide configured global filters to particular users, user groups or roles, so that they can easily select and (de)activate a global filter without the need to configure it on their own. This possibility permits LUY admins or experts to support more inexperienced users in their reduction of data complexity and with a better focus on relevant data.  

  • Any former "personal global filter" (LUY version <7.3.0) will be automatically migrated to a global filter and activated if the "personal global filter" was activated before. 

For more details, see Global filter in the user guide.

1.2 Meta model administration

A new meta model administration facilitates the overview and editing of all building block types, self-relations and relations of your LUY meta model configuration. 

  • A list of all building block types (first tab of the meta model administration) facilitates the overview and selection of all building block types that are (de)activated for the meta model.

  • By unselecting ("hiding") a building block type, the building block type list and any building blocks of its type are no longer accessible for any user and cannot be used for any relation or diagram/report configuration in LUY.

  • For each building block type and relation, now a singular name can be defined in addition to the plural name. The singular name will be used in multiple places across LUY, e.g., in the configuration menu of diagrams, diagram legend or meta model list. 

As the singular name cannot be empty, the plural names defined in your previous version of LUY will be set for the new "singular" fields of building block types and relations by default. Some manual action will be required if you wish to define the correct singular form for building block types and relations.

  • The functional permission "edit meta model" is required to see and access the meta model administration.

  • Each building block type can be edited (second tab of the meta model administration), to review and modify the singular and plural names, persistent names, abbreviations, descriptions and translations of the type, its possible relations and self-relations.

  • An edited meta model administration will be applied globally after saving all changes.

For more details, see Meta model in the user guide.

2. Improvements

2.1 Diagram configuration

The diagram configuration has been adapted for a more consistent and intuitive usage 

  • The two formerly separated dropdowns for the selection of a building block type/relation/self-relation and of an attribute type are now combined in one dropdown. Building block types, relations, self-relations and attributes are listed below each other. 

  • In the diagram tool area, a new configuration button opens an identical configuration menu to the one available when creating a new diagram, in order to facilitate diagram editing. The button replaces the former dropdown selection.

  • For the configuration of most diagrams, you can now freely select from the required fields (e.g., content, columns and rows for the landscape diagram) in an individual order; other options will automatically adapt by showing all remaining possibilities. Previously, you had to follow the order of the fields from top to bottom. 

For more details, see the information about each diagram in the user guide.

2.1 Diagram legend

The new look & feel of the diagram legend facilitates the interpretation of diagram configurations, ensuring that a visualization will be understood at one glance by the creators as well as any diagram consumers. 

  • The report name and description provide important context about the diagram.

  • The new formatting of the legend shifts the focus to the configurations applied (e.g., filters, sorting, coloring) and data hierarchies.

  • In case a partial limit has been set to restrict the data displayed in the diagram for performance improvements with big data, a hint in the legend will inform diagram consumers that not all existing elements are currently being displayed.

  • The export includes the new diagram legend design.

For more details, see the information about each diagram in the user guide.

2.2 Notifications

For a better overview of incoming notifications on changes to data by other users, you can now clean up the notifications dropdown with a few clicks and keep only those notifications in “read notifications” that are relevant to you.

  • You may manually dismiss single notifications using the delete icon “x” or delete all notifications at once via a “clear all” button.

  • All read notifications will be auto-deleted after 30 days, and unread notifications will be auto-deleted after 90 days.  

  • Deleting notifications improves the overview of notifications, speeds up loading times and improves scrolling the notification dropdown menu.

For more details, see notifications in the user guide.

2.3 Hierarchy level aggregation

We have made some adjustments to the aggregation of hierarchical elements in the landscape and cluster diagram. 

  • Some corrections for displaying aggregated elements have been made.

    The slider handle in the row editors of the cluster diagram, and in the display menu of the landscape diagram has been slightly adjusted.

  • In the cluster diagram, aggregated attribute values can be sorted (ascending/descending) and filtered (by row attribute filter).

  • Default system attributes of a building block (e.g., id, position, hierarchy level) are not aggregated since they are always assigned to a specific building block and cannot be "inherited" by another.

  • The colors of relation attribute values are not aggregated, i.e., not inherited from/to an aggregated relation. Relation attributes always show their own assigned color. 

Some of your saved Cluster or Landscape diagram configurations with an activated hierarchy level aggregation might have slightly changed to correctly show the aggregated elements. 

Please note that the position of an element will change according to the aggregation to a higher/lower hierarchy level, but the color of the element will not change in the same way. 

2.4 Some more highlights

  • Reports that users are not entitled to open are shown as semi-transparent entries in the user’s list of all reports
    For users that do not have at least a "read" permission on all building block types used in a report, this report will be shown as a semi-transparent entry in their list of all reports, in order to visualize that those users cannot open the report.

  •  Report permission changes during editing
    When another user has shared a report with you and changes your permission for the shared report or deletes the report while you are working on it, an info message will inform you about the changes and ask you to reload the report.

  • "Select all" button for building block types and relations on the attribute edit page
    You can now select all building block types or relations for an attribute at once on the attribute edit page.

  • Highlight one information system and its directly related information flows and information systems in the information flow diagram
    By clicking on one information system (node), all information flows (edges) and information systems directly related to this information system will be highlighted. The highlighted view can be exported, too.

3. Fixed bugs

  • Fixed an issue when copying a building block with a responsibility attribute assigned.

  • Fixed an issue where no plugin API logs were written in some scripts.

  • Fixed an issue that displayed an incorrect error message for missing permissions.

  • Fixed an issue that in some cases, a relation column could not be added to lists in the query console.

4. Important information

  • An automatic session timeout after five minutes of inactivity has been applied as a default. This ensures continuous performance across various usage and security scenarios of LUY. 

  • Please note that when using the user authentication LDAP or iTurm, re-authentication with the user's credentials is required if the browser is closed and only reopened after the session timeout expired.

  • As of this version, the "Beta" feature diagram builder is no longer available in LUY.

  • As of this version, Java 8 is no longer supported.

  • This is the last full version of LUY supporting the Microsoft Edge Legacy browser. As of version 7.4.0, only Google Chrome, Microsoft Edge (=Chromium-based) and Mozilla Firefox will be supported in their respective stable release versions.

  • This is the last full version of LUY supporting the current custom dashboard.
