@ -17,6 +17,7 @@ The following tip changes can be tested by building VictoriaMetrics components f
FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add support for `alert_relabel_configs` option at `-notifier.config`. This option allows configuring relabeling rules for alerts before sending them to configured notifiers. See [these docs](https://docs.victoriametrics.com/vmalert.html#notifier-configuration-file) for details.
BUGFIX: properly propagate limits at `-search.max*` command-line flags from `vminsert` to `vmstorage`. The limits are `-search.maxUniqueTimeseries`, `-search.maxSeries`, `-search.maxFederateSeries`, `-search.maxExportSeries`, `-search.maxGraphiteSeries` and `-search.maxTSDBStatusSeries`. They weren't propagated to `vmstorage` because of the bug. These limits were introduced in [v1.76.0](https://docs.victoriametrics.com/CHANGELOG.html#v1760).
BUGFIX: fix goroutine leak and possible deadlock when importing invalid data via [native binary format](https://docs.victoriametrics.com/#how-to-import-data-in-native-format). See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2423).
BUGFIX: [Graphite Render API](https://docs.victoriametrics.com/#graphite-render-api-usage): properly calculate [hitCount](https://graphite.readthedocs.io/en/latest/functions.html#graphite.render.functions.hitcount) function. Previously it could return empty results if there were no original samples in some parts of the selected time range.
BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): allow overriding built-in function names inside [WITH templates](https://play.victoriametrics.com/promql/expand-with-exprs). For example, `WITH (sum(a,b) = a + b + 1) sum(x,y)` now expands into `x + y + 1`. Previously such a query would fail with `cannot use reserved name` error. See [this bugreport](https://github.com/VictoriaMetrics/metricsql/issues/5).
