* BUGFIX: [vmauth](https://docs.victoriametrics.com/vmauth.html): suppress [proxy protocol](https://www.haproxy.org/download/2.3/doc/proxy-protocol.txt) parsing errors in case of `EOF`. Usually, the error is caused by health checks and is not a sign of an actual error.
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix displaying errors for each query. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3987).
* BUGFIX: [vmbackup](https://docs.victoriametrics.com/vmbackup.html): fix snapshot not being deleted in case of error during backup. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2055).
* BUGFIX: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation.html): suppress `series after dedup` error message in logs when `-remoteWrite.streamAggr.dedupInterval` command-line flag is set at [vmagent](https://docs.victoriametrics.com/vmgent.html) or when `-streamAggr.dedupInterval` command-line flag is set at [single-node VictoriaMetrics](https://docs.victoriametrics.com/).
* BUGFIX: allow using dashes and dots in environment variables names referred in config files via `%{ENV-VAR.SYNTAX}`. See [these docs](https://docs.victoriametrics.com/#environment-variables) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3999).
* BUGFIX: return back query performance scalability on hosts with big number of CPU cores. The scalability has been reduced in [v1.86.0](https://docs.victoriametrics.com/CHANGELOG.html#v1860). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3966).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly convert [VictoriaMetrics historgram buckets](https://valyala.medium.com/improving-histogram-usability-for-prometheus-and-grafana-bc7e5df0e350) to Prometheus histogram buckets when VictoriaMetrics histogram contain zero buckets. Previously these buckets were ignored, and this could lead to missing Prometheus histogram buckets after the conversion. Thanks to @zklapow for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4021).
