Obcerv Overview 1.4.0
Released: 7 February 2023
New features and enhancements
These are the new features and enhancements of this release:
| Issue key | Release description |
|---|---|
| HASO-612 | When clicking Severity Chips, switching between views now only modifies its own group. |
| HASO-615 | When clicking on the group title, opacity has been removed from elements (Enable/Disable on the top bar and on group section chips, and Expand/Collapse on the top bar and on the accordion) while saveUserConfig is saving. |
| HASO-623 | In table view, the Last Observed label has been changed to Inactive Since. |
Issues fixed
These are the issues we have fixed in this release:
| Issue key | Release description |
|---|---|
| HASO-484 | Switching views between Summary to Tiles and vice versa and Table to Summary and vice versa now works correctly. |
| HASO-509 | Clicking an item in the tree view while data is being loaded no longer displays the No metrics available message. |
| HASO-553 | When the metric table is loading, an indicator is now displayed instead of the There are no metrics available message. |
| HASO-561 | If there is not enough space, the group tool bar information now wraps to another line and shows an ellipsis to indicate longer strings. |
| HASO-562 | When a classification is displayed in view mode and the Edit button is clicked, the classification now goes into edit mode. |
| HASO-570 | On Summary tiles, you can now see quantities of up to 5 figures without ellipses, while the total uses up the free space. |
| HASO-582 | The API call for the filter no longer fires when there are only blank spaces. |
| HASO-587 | False errors have been removed from the web console for when an API request is cancelled if it is no longer needed. |

| HASO-597 | Breadcrumbs now fit into their designated space. |
| HASO-598 | Responsiveness has been improved so that the button to expand the group does not overlap with other elements at smaller screen resolutions. |
| HASO-608 | When you repeatedly click the Enable/Disable actions on chips and Expand/Collapse on the accordion, another API request is sent without waiting for the previous one to finish. This error has been resolved by disabling the components once a request has been made to avoid multiple API calls. |
| HASO-610 | Time window has been added to the API call so that the first level in the tree view now excludes inactive entities. |
| HASO-621 | Each timeline bucket is now assigned a unique key in order to avoid duplicate elements being rendered on the UI. |

Resolved known issues
This section provides the list of known issues that have been resolved in this release.
| Issue key | Release description |
