 ### Synthetic Monitoring

 - If an Instana application was deleted, the links to that application from Synthetic tests were retained, and the Synthetic tests with such links could not be updated. Now if an Instana application is deleted, the links in the Synthetic tests that are associated with that application are automatically removed.
 - The `An unexpected error occurred` error message was displayed in the **Locations** tab if no Synthetic PoPs were deployed. Now the `No data available` message is displayed in the **Locations** tab if no Synthetic PoPs are deployed.
 - In the **Results** tab for a Synthetic test, you were not able to filter Synthetic results from the deleted locations. Now you can filter Synthetic test results from the deleted locations. In the **Results** tab for a Synthetic test, you can select the name of the deleted location by using the Location filter to see the results from the deleted location within the selected time range.
+- If a location was deleted without uninstalling the PoP, the existing tests were still running in the PoP, and the test results were sent to the backend. The issue is fixed now. If the location is deleted, the tests are cleared in the PoP, and no new test results are sent to the backend.
+- If a REST API returned a response with the header `content-encoding: utf-8`, the API script that tested this API failed with the error message `Not able to decode utf-8`. The issue is fixed now.

+### Unbounded Analytics
+
+In the Unbounded Analytics page, if a tag filter value was blank, the value suggestions of other tag filters couldn't be loaded.
+
+The issue is fixed now. Even though a tag filter value is blank, you can still see the value suggestions for other tag filters.

+### KPI Card Layout
 
+The layout of the KPI Cards on the Application and Service Summary pages is adjusted to match other screens when the window size is reduced.
