* FEATURE: allow splitting long `regex` in relabeling filters into an array of shorter regexps, which can be put into multiple lines for better readability and maintainability. See [these docs](https://docs.victoriametrics.com/vmagent.html#relabeling) for more details.
|
||||
* FEATURE: optimize performance for queries with regexp filters on metric name like `{__name__=~"metric1|...|metricN"}`. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1610) from @faceair.
|
||||
* FEATURE: vmui: use Prometheus-compatible query args, so `vmui` could be accessed from graph editor in Grafana. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1619). Thanks to @Loori-R.
|
||||
* FEATURE: vmselect: automatically add missing port to `-storageNode` hostnames. For example, `-storageNode=vmstorage1,vmstorage2` is automatically translated to `-storageNode=vmstorage1:8401,vmstorage2:8401`. This simplifies [manual setup of VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#cluster-setup).

* FEATURE: vminsert: automatically add missing port to `-storageNode` hostnames.

This simplifies [manual setup of VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#cluster-setup).
|

|
||||
* BUGFIX: properly handle queries with multiple filters matching empty labels such as `metric{label1=~"foo|",label2="bar|"}`. This filter must match the following series: `metric`, `metric{label1="foo"}`, `metric{label2="bar"}` and `metric{label1="foo",label2="bar"}`. Previously it was matching only `metric{label1="foo",label2="bar"}`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1601).
|
||||
* BUGFIX: vmselect: reset connection timeouts after each request to `vmstorage`. This should prevent from `cannot read data in 0.000 seconds: unexpected EOF` warning in logs. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1562). Thanks to @mxlxm .

A minimal cluster must contain the following nodes:

1. Start new `vmstorage` node with the same `-retentionPeriod` as existing nodes in the cluster.

Whether to treat dots as is in regexp label filters used in queries.
