* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): reduce memory usage when sending stale markers for targets, which expose big number of metrics. See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3668) and [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3675) issues. * FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): reduce memory usage when sending stale markers for targets, which expose big number of metrics. See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3668) and [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3675) issues.
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): allow limiting the number of concurrent requests sent to `vmauth` via `-maxConcurrentRequests` command-line flag. This allows controlling memory usage of `vmauth` and the resource usage of backends behind `vmauth`. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3346). Thanks to @dmitryk-dk for [the initial implementation](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3486). * FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): allow limiting the number of concurrent requests sent to `vmauth` via `-maxConcurrentRequests` command-line flag.

* FEATURE: allow using VictoriaMetrics components behind proxies, which communicate with the backend via [proxy protocol](https://www.haproxy.org/download/2.3/doc/proxy-protocol.txt). See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3335). For example, [vmauth](https://docs.victoriametrics.com/vmauth.html) accepts proxy protocol connections when it starts with `-httpListenAddr.useProxyProtocol` command-line flag. * FEATURE: allow using VictoriaMetrics components behind proxies, which communicate with the backend via [proxy protocol](https://www.haproxy.org/download/2.3/doc/proxy-protocol.txt).

* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `__meta_kubernetes_pod_container_id` meta-label to the targets discovered via [kubernetes_sd_configs](https://docs.victoriametrics.com/sd_configs.html#kubernetes_sd_configs). This label has been added in Prometheus starting from `v2.42.0`. See [this feature request](https://github.com/prometheus/prometheus/issues/11843).
* FEATURE: add `-internStringMaxLen` command-line flag, which can be used for fine-tuning RAM vs CPU usage in certain workloads. For example, if the stored time series contain long labels, then it may be useful reducing the `-internStringMaxLen` in order to reduce memory usage at the cost of increased CPU usage. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3692). * FEATURE: add `-internStringMaxLen` command-line flag, which can be used for fine-tuning RAM vs CPU usage in certain workloads.

* BUGFIX: fix a bug, which could prevent background merges for the previous partitions until restart if the storage didn't have enough disk space for final deduplication and down-sampling. * BUGFIX: fix a bug, which could prevent background merges for the previous partitions until restart if the storage didn't have enough disk space for final deduplication and down-sampling.
