* BUGFIX: align behavior of the queries `a or on (labels) b`, `a and on (labels) b` and `a unless on (labels) b` where `b` has multiple time series with the given `labels` to Prometheus behavior. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1643).
* BUGFIX: vmagent: fix `openstack_sd_config` service discovery when both `domain_name` and `project_id` config options are set. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1655).
* BUGFIX: return proper values (zeroes) from [stddev_over_time](https://docs.victoriametrics.com/MetricsQL.html#stddev_over_time) and [stdvar_over_time](https://docs.victoriametrics.com/MetricsQL.html#stdvar_over_time) functions when the lookbehind window in square brackets contains only a single sample. Previously the sample value was incorrectly returned in this case.
* BUGFIX: vminsert: fix uneven distribution of time series among storage nodes in [multi-level cluster setup](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#multi-level-cluster-setup). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1672).
