 ==== Fixes
 * Removes `null` in confirmation dialog when bulk editing index patterns for rules ({kibana-pull}236572[#236572]).
 * Fixes the URL passed to detection rule actions via the `{{context.results_link}}` placeholder ({kibana-pull}236067[#236067]).
-* Adds support in {elastic-defend} for installing eBPF probes on Linux endpoints when taskstats is compiled out of the kernel.
 * Fixes a bug in {elastic-defend} where Linux network events could have source and destination bytes swapped.
 * Removes `.process.thread.capabilities.permitted` and `.process.thread.capabilities.effective` from Linux network events in {elastic-defend}.
 * Fixes a bug in {elastic-defend} where host isolation could auto-release incorrectly. Host isolation now only releases when {elastic-endpoint} becomes orphaned. Intermittent {elastic-agent} connectivity changes no longer alter the host isolation state.
