 * FEATURE: vmagent: reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics. See more information about `series_limit` [here](https://docs.victoriametrics.com/vmagent.html#cardinality-limiter).
 * FEATURE: vminsert: disable rerouting by default when a few of `vmstorage` nodes start accepting data at lower speed than the rest of `vmstorage` nodes. This should improve VictoriaMetrics cluster stability during rolling restarts and during spikes in [time series churn rate](https://docs.victoriametrics.com/FAQ.html#what-is-high-churn-rate). The rerouting can be enabled by passing `-disableRerouting=false` command-line flag to `vminsert`.
 * FEATURE: vmauth: do not put invalid auth tokens into log by default due to security reasons. The logging can be returned back by passing `-logInvalidAuthTokens` command-line flag to `vmauth`. Requests with invalid auth tokens are counted at `vmagent_http_request_errors_total{reason="invalid_auth_token"}` metric exposed by `vmauth` at `/metrics` page.
+* 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.
 
 * 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 .
