+==== Enhancements
+* Improves the reliability of {elastic-defend}'s connection to its kernel driver. This should reduce the instances of temporary `DEGRADED` policy statuses at boot due to `connect_kernel` failures.
+* Enriches {elastic-defend} macOS network connect events with `network.direction`. Possible values are `ingress` and `egress`.

+==== Fixes
+* Fixes a bug in Session View where `args` fields in `event.process` and nested objects had string values instead of array of strings as expected ({kibana-pull}232462[#232462]).
+* Fixes a bug in {elastic-defend} where Linux endpoints would report `process.executable` as a relative, instead of absolute, path.
+* Fixes a bug where {elastic-defend} Linux network events would fail to load if IPv6 is not supported by the system.
+* Fixes a bug in {elastic-defend} where the `fqdn` feature flag was not being persisted across system or endpoint restarts.
+* Fixes a race condition in {elastic-defend} on Windows that occasionally resulted in corrupted process command lines. This could cause incorrect values for `process.command_line`, `process.args_count`, and `process.args`, leading to false positives.
+* Hides case connectors in the create case workflow based on your license ({kibana-pull}232506[#232506]).
+* Fixes inconsistencies in case activity statistics ({kibana-pull}231948[#231948]).
