+==== Fixes
+* Fixes an issue with editing filters on the **Alerts** page ({kibana-pull}236756[#236756]).
+* Prioritizes connector `defaultModel` over stored conversation model ({kibana-pull}237947[#237947]).
+* Fixes an {elastic-defend} issue in malware protection for Linux where a deadlock could sometimes occur when containers and autofs were both active.
+* Fixes an {elastic-defend} issue on Linux by preventing unnecessary locking within malware protection to avoid invalid watchdog firings.
+* Fixes issues that could sometimes cause crashes of the {elastic-defend} user-mode process on very busy Windows systems.
+* Fixes an {elastic-defend} issue on Windows which could allow a low-privilege attacker to delete arbitrary files on the system. On versions of Windows before Windows 11 24H2, this could result in local privilege escalation.
+* Fixes an {elastic-defend} bug in Linux event collection where some long-running processes were not enriched.
