* SECURITY: upgrade Go builder from Go1.21.6 to Go1.22.0. See [the list of issues addressed in Go1.21.7](https://github.com/golang/go/issues?q=milestone%3AGo1.21.7+label%3ACherryPickApproved),
plus [the changelog for Go1.22.0](https://go.dev/doc/go1.22).
* 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). See [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 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 flag values in short array notation. For example, `-remoteWrite.sendTimeout=',20s,'` specifies three `-remoteWrite.sendTimeout` values - the first and the last ones are default values (`30s` in this case), while the second one is `20s`.

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). See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1547).

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`. Setting 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).

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).
* FEATURE: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): add `-disableReroutingOnUnavailable` command-line flag to `vminsert`, which can be used for reducing resource usage spikes at `vmstorage` nodes during rolling restart. See [these docs](https://docs.victoriametrics.com/cluster-victoriametrics/#improving-re-routing-performance-during-restart). Thanks to @Muxa1L for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5713).
* FEATURE: add `-search.resetRollupResultCacheOnStartup` command-line flag for resetting [query cache](https://docs.victoriametrics.com/#rollup-result-cache) on startup. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/834).
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): propagate label filters across [label_set](https://docs.victoriametrics.com/MetricsQL.html#label_set) and [alias](https://docs.victoriametrics.com/MetricsQL.html#alias) functions. For example, `label_set(q1, "a", "b") + q2{c="d"}` is automatically transformed to `label_set(q1{c="d"}, "a", "b") + q2{a="b",c="d"}` now. This should improve performance for such queries. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1827#issuecomment-1654095358).
