 * FEATURE: allow specifying TLS cipher suites for incoming https requests via `-tlsCipherSuites` command-line flag. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2404).
 * FEATURE: allow specifying TLS cipher suites for mTLS connections between cluster components via `-cluster.tlsCipherSuites` command-line flag. See [these docs](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#mtls-protection).
 * FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): shown an empty graph on the selected time range when there is no data on it. Previously `No data to show` placeholder was shown instead of the graph in this case. This prevented from zooming and scrolling of such a graph.
+* FEATURE: expose `vm_indexdb_items_added_total` and `vm_indexdb_items_added_size_bytes_total` counters at `/metrics` page, which can be used for monitoring the rate for addition of new entries in `indexdb` (aka `inverted index`) alongside the total size in bytes for the added entries. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2471).
 
 * BUGFIX: [vmctl](https://docs.victoriametrics.com/vmctl.html): return non-zero exit code on error. This allows handling `vmctl` errors in shell scripts. Previously `vmctl` was returning 0 exit code on error. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2322).
 * BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly show `scrape_timeout` and `scrape_interval` options at `http://vmagent:8429/config` page. Previously these options weren't displayed even if they were set in `-promscrape.config`.
