 ==== Enhancements
 * Makes {elastic-defend} malware scan queue operate more efficiently by not blocking scan requests when an oplock for the file being scanned cannot be acquired.
 * To help identify which parts of `elastic-endpoint.exe` are using a significant amount of CPU, {elastic-defend} on Windows can now include CPU profiling data in diagnostics. To request CPU profiling data via the command line, refer to the {fleet-guide}/elastic-agent-cmd-options.html#_options[Agent command reference]. To request CPU profiling data via Kibana, check the **Collect additional CPU metrics** box when requesting {agent} diagnostics.  
+* Shortens the time it takes for {elastic-defend} to recover from a DEGRADED status caused by Elastic Agent communication issues.
+* Allows {elastic-defend} to automatically recover in some situations when it loses connectivity with {agent}.
