**Update note:** this release changes data format for [/api/v1/export/native](https://docs.victoriametrics.com/#how-to-export-data-in-native-format) in incompatible way, so it cannot be imported into older version of VictoriaMetrics via [/api/v1/import/native](https://docs.victoriametrics.com/#how-to-import-data-in-native-format).
* FEATURE: check the correctess of raw sample timestamps stored on disk when reading them. This reduces the probability of possible silent corruption of the data stored on disk. This should help [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2998) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3011).
* FEATURE: set the `start` arg to `end - 5 minutes` if isn't passed explicitly to [/api/v1/labels](https://docs.victoriametrics.com/url-examples.html#apiv1labels) and [/api/v1/label/.../values](https://docs.victoriametrics.com/url-examples.html#apiv1labelvalues). See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3052).
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): add `vm-native-step-interval` command line flag for `vm-native` mode. New option allows splitting the import process into chunks by time interval. This helps migrating data sets with high churn rate and provides better control over the process. See [feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2733).
* 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).
* BUGFIX: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): properly calculate query results at `vmselect`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3067). The issue has been introduced in [v1.81.0](https://docs.victoriametrics.com/CHANGELOG.html#v1810).
* BUGFIX: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): log clear error when multiple identical `-storageNode` command-line flags are passed to `vmselect` or to `vminsert`. Previously these components were crashed with cryptic panic `metric ... is already registered` in this case. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3076).
