+## Load Testing
+
+* Live Error Reporting
+    * When using a custom time period, changing the values in the From/To fields using the keyboard had no effect. Now the change takes effect when the date/time input field loses focus.
+    * Fixed a problem that caused the histogram to flicker every five seconds while a load test was running.
+* Minor UI improvements.
+* Currently available XLT execution environments:
+    * XLT 8.x → [8.4.0]({{< relref "/xlt/release-notes/8_4_x" >}})
+
+
+## Monitoring
+
+* On the Scenario Execution History page, using the keyboard to change the values in the From/To fields at the top had no effect. Now the change takes effect when the date/time input field loses focus.
+* Minor usability improvements.
