* BUGFIX: reduce the probability of `duplicate time series` errors when querying Kubernetes metrics.
* BUGFIX: properly calculate `histogram_quantile()` over time series with only a single non-zero bucket with `{le="+Inf"}`. Previously `NaN` was returned, now the value for the last bucket before `{le="+Inf"}` is returned like Prometheus does.
* BUGFIX: vmselect: do not cache partial query results on timeout when receiving data from `vmstorage` nodes. See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1085
* BUGFIX: properly handle `stale NFS file handle` error.
