 - [#4552](https://github.com/thanos-io/thanos/pull/4552) Compact: Adds `thanos_compact_downsample_duration_seconds` histogram.
 - [#4594](https://github.com/thanos-io/thanos/pull/4594) reloader: Expose metrics in config reloader to give info on the last operation.

If your downstream URL is localhost or 127.0.0.1 then it is strongly recommended to bump `max_idle_conns_per_host` to at least 100 so that `query-frontend` could properly use HTTP keep-alive connections and thus reduce the latency of `query-frontend` by about 20%.
