* FEATURE: reduce memory usage by up to 30% on production workloads.
* FEATURE: log http request path plus all the query args on errors during request processing. Previously only http request path was logged without query args, so it could be hard debugging such errors.
* FEATURE: export `vmselect_request_duration_seconds` and `vminsert_request_duration_seconds` [VictoriaMetrics histograms](https://valyala.medium.com/improving-histogram-usability-for-prometheus-and-grafana-bc7e5df0e350) at `/metrics` page. These histograms can be used for determining latency distribution for the served requests.
* FEATURE: vmselect: embed [vmui](https://github.com/VictoriaMetrics/vmui) into a single-node VictoriaMetrics and into `vmselect` component of cluster version. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1413). The web interface is available at `/ui` page.
* FEATURE: vmselect: embed [vmui](https://github.com/VictoriaMetrics/vmui) into a single-node VictoriaMetrics and into `vmselect` component of cluster version. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1413). The web interface is available at the following paths:
* `/ui/` for a single-node VictoriaMetrics
* `/select/<accountID>/prometheus/ui/` for `vmselect` at cluster version of VictoriaMetrics
* BUGFIX: vmagent: remove `{ %space %}` typo in `/targets` output. The typo has been introduced in v1.62.0. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1408).
* BUGFIX: vmagent: fix CSS styles on `/targets` page. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1422).
