When using [cluster version of VictoriaMetrics](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html), these command-line flags (including `-search.maxUniqueTimeseries`) must be passed to `vmselect` instead of `vmstorage`.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html) and [vmauth](https://docs.victoriametrics.com/vmauth.html): reduce the probability of `TLS handshake error from XX.XX.XX.XX: EOF` errors when `-remoteWrite.url` points to HTTPS url at `vmauth`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1699).
* BUGFIX: return `Content-Type: text/html` response header when requesting `/` HTTP path at VictoriaMetrics components. Previously `text/plain` response header was returned, which could lead to broken page formatting. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2323).
