 * BUGFIX: `vmselect`: improve performance and memory usage during query processing on machines with big number of CPU cores. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5087).
 * BUGFIX: dashboards: fix vminsert/vmstorage/vmselect metrics filtering when dashboard is used to display data from many sub-clusters with unique job names. Before, only one specific job could have been accounted for component-specific panels, instead of all available jobs for the component.
 * BUGFIX: dashboards: respect `job` and `instance` filters for `alerts` annotation in cluster and single-node dashboards.
+* BUGFIX: dashboards: update description for RSS and anonymous memory panels to be consistent for single-node, cluster and vmagent dashboards.
 * BUGFIX: dashboards/vmalert: apply `desc` sorting in tooltips for vmalert dashboard in order to improve visibility of the outliers on graph.
 * BUGFIX: dashboards/vmalert: properly apply time series filter for panel `No data errors`. Before, the panel didn't respect `job` or `instance` filters.
 * BUGFIX: dashboards/vmalert: fix panel `Errors rate to Alertmanager` not showing any data due to wrong label filters.
