For example, `label_del(some_metric{job="foo"}, "instance") + other_metric{pod="bar"}` is now transformed to `label_del(some_metric{job="foo",pod="bar"}, "instance") + other_metric{job="foo",pod="bar"}`. This should reduce the amounts of time series processed during query execution. * FEATURE: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): expose `vm_last_partition_parts` [metrics](https://docs.victoriametrics.com/#monitoring), which show the number of [parts in the latest partition](https://docs.victoriametrics.com/#storage). These metrics may help debugging query performance slowdown related to the increased number of parts in the last partition, since usually all the ingested data is written to the last partition and all the queries are performed over the recently ingested data, e.g. the last partition. +* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add support for `client_id` option into [kuma_sd_configs](https://docs.victoriametrics.com/sd_configs/#kuma_sd_configs) in the same way as Prometheus does. See [this pull request](https://github.com/prometheus/prometheus/pull/13278). * FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): support client-side TLS configuration for [InfluxDB](https://docs.victoriametrics.com/vmctl/#migrating-data-from-influxdb-1x). See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5748). Thanks to @khushijain21 for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5783). * FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): support client-side TLS configuration for [Remote Read protocol](https://docs.victoriametrics.com/vmctl/#migrating-data-by-remote-read-protocol). See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5748). Thanks to @khushijain21 for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5798). * FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): preserve [`WITH` templates](https://play.victoriametrics.com/select/accounting/1/6a716b0f-38bc-4856-90ce-448fd713e3fe/expand-with-exprs) when clicking the `prettify query` button at the right side of query input field.
