## tip
## [v1.81.1](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.81.1)
Released at 02-09-2022
* 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).
