* FEATURE: all VictoriaMetrics components: add support for TLS client certificate verification at `-httpListenAddr` (aka [mTLS](https://en.wikipedia.org/wiki/Mutual_authentication)). See [these docs](https://docs.victoriametrics.com/#mtls-protection) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5458).
* FEATURE: all VictoriaMetrics components: add support for accepting http requests over multiple distinct TCP addresses. This can be done by starting VictoriaMetrics component with multiple `-httpListenAddr` command-line flags. For example, `./victoria-metrics -httpListenAddr=some-host:12345 -httpListenAddr=localhost:8428` starts VictoriaMetrics, which accepts incoming http requests at both `some-host:12345` and `localhost:8428`. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1470).
* FEATURE: all VictoriaMetrics components: add support for empty command-line flag values in short array notation. For example, `-remoteWrite.sendTimeout=',20s,'` specifies three `-remoteWrite.sendTimeout` values - the first one and the last one have default values (`30s` in this case), while the second one is set to `20s`.
* FEATURE: all VictoriaMetrics components: do not close connections to `-httpListenAddr` every 2 minutes. This behavior didn't help spreading load among multiple backend servers behind load-balancing TCP proxy. Instead, it could lead to hard-to-debug issues like [this one](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1636997037). If you still need periodically closing client connections because of some reason, then pass the desired timeout to `-http.connTimeout` command-line flag.
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): add support for [mTLS](https://en.wikipedia.org/wiki/Mutual_authentication)-based request routing to different backends depending on the subject of the TLS certificate provided by the client. See [these docs](https://docs.victoriametrics.com/vmauth.html#mtls-based-request-routing) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1547).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html) and [single-node VictoriaMetrics](https://docs.victoriametrics.com): add support for data ingestion via [DataDog lambda extension](https://docs.datadoghq.com/serverless/libraries_integrations/extension/) aka `/api/beta/sketches` endpoint. See [these docs](https://docs.victoriametrics.com/#how-to-send-data-from-datadog-agent) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3091). Thanks to @AndrewChubatiuk for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5584).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `-remoteWrite.tlsHandshakeTimeout` command-line flag for tuning the timeout needed for establishing TLS connections to `-remoteWrite.url`. Bigger tls handshake timeouts should reduce the probability of `http: TLS handshake error from ...: EOF` errors at the remote storage side under high load. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1699).
