@ -174,8 +174,7 @@ The v1.79.x line will be supported for at least 12 months since [v1.79.0](https:
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): ignore empty series when applying [limit_offset](https://docs.victoriametrics.com/MetricsQL.html#limit_offset). It should improve queries with additional filters by value in expressions like `limit_offset(1,1, foo > 1)`.
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly calculate [quantiles_over_time](https://docs.victoriametrics.com/MetricsQL.html#quantiles_over_time) when the lookbehind window contains only a single sample. Previously an empty result was incorrectly returned in this case.
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix `RangeError: Maximum call stack size exceeded` error when the query returns too many data points at `Table` view. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3092/files).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): re-evaluate annotations per each alert evaluation. Previously, annotations were evaluated only on alert's value ch
ange. This could result in stale annotations in some cases described in [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3119).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): re-evaluate annotations per each alert evaluation. Previously, annotations were evaluated only on alert's value change. This could result in stale annotations in some cases described in [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3119).
* BUGFIX: prevent from excessive CPU usage when the storage enters [read-only mode](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#readonly-mode). The previous fix in [v1.79.3](https://docs.victoriametrics.com/CHANGELOG.html#v1793) wasn't complete.
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): change default value for command-line flag `-datasource.queryStep` from `0s` to `5m`. Param `step` is added by vmalert to every rule evaluation request sent to datasource. Before this change, `step` was equal to group's evaluation interval by default. Param `step` for instant queries defines how far VM can look back for the last written data point. The change supposed to improve reliability of the rules evaluation when evaluation interval is lower than scraping interval.
* BUGFIX: properly calculate `vm_rows_scanned_per_query` histogram exported at `/metrics` page of `vmselect` and single-node VictoriaMetrics. Previously it could return misleadingly high numbers for [rollup functions](https://docs.victoriametrics.com/MetricsQL.html#rollup-functions), which scan only a few samples on the provided lookbehind window in square brackets. For example, `increase(m[1d])` always scans only 2 rows (aka `raw samples`) per each returned time series.
