 * FEATURE: vmagent: optimize [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling) performance for common cases.
 * FEATURE: add `increase_pure(m[d])` function to MetricsQL. It works the same as `increase(m[d])` except of various edge cases. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/962) for details.
 * FEATURE: increase accuracy for `buckets_limit(limit, buckets)` results for small `limit` values. See [MetricsQL docs](https://docs.victoriametrics.com/MetricsQL.html) for details.
-* FEATURE: vmagent: initial support for Windows build with `CGO_ENABLED=0 GOOS=windows go build -mod=vendor ./app/vmagent`. See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/70) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1036).
