* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): accept data ingestion requests via paths starting from `/prometheus` prefix in the same way as [VictoriaMetrics does](https://docs.victoriametrics.com/#how-to-import-time-series-data). For example, `vmagent` now accepts Prometheus `remote_write` data via both `/api/v1/write` and `/prometheus/api/v1/write`. This simplifies switching between single-node VictoriaMetrics and `vmagent`.
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `external_labels` from `global` section at `-promscrape.config` after the [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling) is applied to scraped metrics. This aligns with Prometheus behaviour. Previously the `external_labels` were added to scrape targets, so they could be modified during relabeling. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3137).
* BUGFIX: [vmauth](https://docs.victoriametrics.com/vmauth.html): properly handle request paths ending with `/` such as `/vmui/`. Previously `vmui` was dropping the traling `/`, which could prevent from using `vmui` via `vmauth`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1752).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly encode query params for aws signed requests, use `%20` instead of `+` as api requires. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3171).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly parse relabel config when regex ending with escaped `$`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3131).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly calculate `rate_over_sum(m[d])` as `sum_over_time(m[d])/d`. Previously the `sum_over_time(m[d])` could be improperly divided by smaller than `d` time range. See [rate_over_sum() docs](https://docs.victoriametrics.com/MetricsQL.html#rate_over_sum) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3045).
