+* 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).

+**It isn't recommended to use VictoriaMetrics cluster v1.81.1 because of [the bug](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3067), which may result in incorrect query results. Upgrade to [v1.81.2](https://docs.victoriametrics.com/CHANGELOG.html#v1812) instead.**

 * FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): evaluate `q1`, ..., `qN` in parallel when calculating `union(q1, .., qN)`. Previously [union](https://docs.victoriametrics.com/MetricsQL.html#union) args were evaluated sequentially. This could result in lower than expected performance.
 
 * BUGFIX: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): fix potential panic at `vmselect` under high load, which has been introduced in [v1.81.0](https://docs.victoriametrics.com/CHANGELOG.html#v1810). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3058).
