* FEATURE: add `-search.maxSamplesPerSeries` command-line flag for limiting the number of raw samples a single query can process per each time series. This option can protect from out of memory errors when a query processes tens of millions of raw samples per series. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1067).
* FEATURE: add `-search.maxSamplesPerQuery` command-line flag for limiting the number of raw samples a single query can process across all the time series. This option can protect from heavy queries, which select too big number of raw samples. Thanks to @jiangxinlingdu for [the initial pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1478).
* BUGFIX: vmbackup: automatically set default `us-east1` S3 region if it is missing. This should simplify using S3-compatible services such as MinIO for backups. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1449).
* BUGFIX: vmselect: return dummy response at `/rules` page in the same way as for `/api/v1/rules` page. The `/rules` page is requested by Grafana 8. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1493) for details.
* BUGFIX: vmbackup: automatically set default `us-east-1` S3 region if it is missing. This should simplify using S3-compatible services such as MinIO for backups. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1449).
* BUGFIX: vmselect: prevent from possible deadlock when multiple `target` query args are passed to [Graphite Render API](https://docs.victoriametrics.com/#graphite-render-api-usage).
* BUGFIX: return series with `a op b` labels and `N` values for `(a op b) default N` if `(a op b)` returns series with all NaN values. Previously such series were removed.
